In cases of overdose, standard supportive measures should be taken as required. Mean (95% C.I.) This dose is approximately 100 fold (rat) and 29 fold (rabbit) greater than the AUC values for unbound vardenafil and its major metabolite in humans given the MRHD of 20 mg. The most potent inhibitory activity was observed for vardenafil metabolite M1, which had a Ki of 1.4 M) toward CYP3A4, which is about 20 times higher than the M1 Cmax values after an 80 mg LEVITRA dose. The maximum decrease in blood pressure occurred between 1 and 4 hours after dosing. The findings were most evident one hour after administration, diminishing but still present 6 hours after administration. maximal change in baseline in systolic blood pressure (mmHg) following vardenafil 10 and 20 mg in healthy volunteers on daily alpha-blocker therapy. The majority of these subjects experienced reversible back pain/myalgia and/or "abnormal vision." Single doses up to 80 mg vardenafil and multiple doses up to 40 mg vardenafil administered once daily over 4 weeks . LEVITRA (20 mg) did not potentiate the hypotensive effects of alcohol during the 4-hour observation period in healthy volunteers when administered with alcohol (0.5 g/kg body weight). This protein binding is reversible and independent of total drug concentrations. This medicine is a orange, round, film-coated, tablet imprinted with "BAYER" and "20". Potentiation of the hypotensive effects of nitrates for patients with ischemic heart disease has not been evaluated, and concomitant use of LEVITRA and nitrates is contraindicated (see CLINICAL PHARMACOLOGY, Pharmacodynamics, Effects on Blood Pressure and Heart Rate When LEVITRA is Combined with Nitrates; CONTRAINDICATIONS). Treatment for erectile dysfunction should generally be used with caution by patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease) or by patients who have conditions that may predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia). g Flexible dose studies started all patients at LEVITRA 10 mg and allowed decrease in dose to 5 mg or increase in dose to 20 mg based on side effects and efficacy. The actual clinical impact of these QTc changes is unknown. maximal change from baseline in systolic blood pressure (mmH following vardenafil 5 mg in BPH patients on stable alpha-blocker therapy (Study 1). This monohydrochloride salt of vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Placebo-controlled trials suggested a dose effect in the incidence of some adverse events (headache, flushing, dyspepsia, nausea, rhinitis) over the 5 mg, 10 mg, and 20 mg doses of LEVITRA. The mean baseline EF Domain score in these trials was 11.8 (scores range from 0-30 where lower scores represent more severe disease). Note: Sexual arousal is needed for a reaction to treatment. Levitra (vardenafil hydrochloride) is an erectile dysfunction agent that works by blocking a certain enzyme (phosphodiesterase-PDE5) used to treat erectile dysfunction ( impotence ). If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 has no effect in the absence of sexual stimulation. Based on how well you respond to this dosage and any side effects you have, your doctor may either increase your dose up to the maximum of 100 mg or decrease your dose to 25 mg. You. Consequently, a starting dose of 5 mg is recommended for patients with moderate hepatic impairment, and the maximum dose should not exceed 10 mg (see PRECAUTIONS and DOSAGE AND ADMINISTRATION). Symptoms of hypotension were a cause for withdrawal in 2 subjects receiving terazosin and in 4 subjects receiving tamsulosin. Results of these studies showed that LEVITRA did not alter the total treadmill exercise time compared to placebo (10 mg LEVITRA vs. placebo: 433 109 and 426 105 seconds, respectively; 20 mg LEVITRA vs. placebo: 414 114 and 411 124 seconds, respectively). In these patients whose hypertension was controlled with nifedipine, LEVITRA 20 mg produced mean additional supine systolic/diastolic blood pressure reductions of 6/5 mm Hg compared to placebo. Stop taking Levitra and contact your physician immediately when you have: Get To Know What Possibly Could Be Causing Your Symptoms! Study 1: This study was designed to evaluate the effect of 5 mg vardenafil compared to placebo when administered to BPH patients on chronic alpha-blocker therapy in two separate cohorts: tamsulosin 0.4 mg daily (cohort 1, n=21) and terazosin 5 or 10 mg daily (cohort 2, n=21). Vardenafil has not been evaluated in patients with severe hepatic impairment (Child-Pugh C). General: In humans, vardenafil alone in doses up to 20 mg does not prolong the bleeding time. Dosage Forms & Strengths tablet, film coated (generic) 2.5mg 5mg 10mg 20mg Erectile Dysfunction 10 mg PO ~1 hour before sexual activity; may be increased to 20 mg or reduced to 5 mg,. Mean QT and QTc changes in msec (90% CI) from baseline relative to placebo at 1 hour post-dose with different methodologies to correct for the effect of heart rate. Ketoconazole (200 mg once daily) produced a 10-fold increase in vardenafil AUC and a 4-fold increase in Cmax when co-administered with LEVITRA (5 mg) in healthy volunteers. Sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis) and avanafil (Stendra) are oral medications that reverse erectile dysfunction by enhancing the effects of nitric oxide, a natural chemical your body produces that relaxes muscles in the penis. The lesser you use Levitra, the less side effects you will experience. Color: orange Shape: round Imprint: BAYER 20. Patients with congenital QT prolongation and those taking Class IA (e.g., quinidine, procainamide) or Class III (e.g.,amiodarone, sotalol) antiarrhythmic medications should avoid using LEVITRA. Renal dialysis is not expected to . Signs of a Gay Husband, Rape Victim Stories: Real Stories of Being Raped, HONcode standard for The maximum recommended dosing frequency is once per day. Recommended Storage: Store at 25C (77F); excursions permitted to 15-30C (59-86F) [see USP controlled room temperature]. maximal change from baseline in systolic blood pressure (mmHg) following vardenafil 10 and 20 mg in BPH patients on stable alpha-blocker therapy with tamsulosin 0.4 or 0.8 mg daily (Study 2). . The improvement in mean score was maintained at all doses at six months in the North American trial. There are no adequate and well-controlled trials of vardenafil in pregnant women. Vardenafil was secreted into the milk of lactating rats at concentrations approximately 10-fold greater than found in the plasma. The number of living pups born to rats exposed pre- and postnatally was reduced at 60 mg/kg/day. For men who are trying Levitra for the first time, the recommended dose is 10mg. LEVITRA is not indicated for use in women, newborns, or children. Therapeutic and supratherapeutic doses of vardenafil and the active control moxifloxacin produced similar increases in QTc interval. It is not possible to determine whether these events were related directly to the use of PDE5 inhibitors or to other factors. ED is often a symptom of another health problem or health-related factor. LEVITRA was dosed without regard to meals on an as needed basis in men with erectile dysfunction (ED), many of whom had multiple other medical conditions. Weak inhibitory effects toward other isoforms (CYP2C8, 2C9, 2C19, 2D6, 3A4) were found, but Ki values were in excess of plasma concentrations achieved following dosing. Levitra effectively works by relaxing the muscles in the walls of the blood vessels to promote flowing of blood to certain areas of the body such as penis. The majority of these subjects experienced reversible back pain/myalgia and/or "abnormal vision". Upon administration of 10 mg of LEVITRA with 800 mg TID indinavir , the Cmax and AUC of indinavir were reduced by 40% and 30%, respectively. However, fatty foods will reduce the effectiveness and efficacy of the pill; you must then avoid such like foods when using this medicine. Following multiple dosing for 31 days, similar blood pressure responses were observed on Day 31 as on Day 1. Maximum observed plasma concentrations after a single 20 mg dose in healthy volunteers are usually reached between 30 minutes and 2 hours (median 60 minutes) after oral dosing in the fasted state. If priapism is not treated immediately, penile tissue damage and permanent loss of potency may result. Renal Insufficiency: In patients with moderate (CLcr = 30-50 ml/min) to severe (CLcr 80 ml/min) (see CLINICAL PHARMACOLOGY, Pharmacokinetics in Special Populations). You may be having serious side effects. Blood Pressure Effects: LEVITRA has systemic vasodilatory properties that resulted in transient decreases in supine blood pressure in healthy volunteers (mean maximum decrease of 7 mmHg systolic and 8 mmHg diastolic) (see CLINICAL PHARMACOLOGY, Pharmacodynamics). For ketoconazole 200 mg daily, itraconazole 200 mg daily, and erythromycin, a single dose of 5 mg LEVITRA should not be exceeded in a 24-hour period. General Dose Information For most patients, the recommended starting dose of Levitra is 10 mg, taken orally, as needed, approximately 60 minutes before sexual activity. Metabolism: Vardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms. Physicians should discuss with patients the contraindication of LEVITRA with regular and/or intermittent use of organic nitrates. Patients prescribed LEVITRA who are taking alpha-blockers should be started on the lowest recommended starting dose of LEVITRA (see Drug Interactiona and DOSAGE AND ADMINISTRATION). Levitra works by increasing blood flow to the penis during sexual stimulation. The maximum recommended dosing frequency is once per day. Because the disease state of patients requiring nitrate therapy is anticipated to increase the likelihood of hypotension, the use of vardenafil by patients on nitrate therapy or on nitric oxide donors is contraindicated (see CONTRAINDICATIONS). Renal Impairment: For patients with mild (CLcr = 50-80 ml/min), moderate (CLcr = 30-50 ml/min), or severe (CLcr <30 ml/min) renal impairment, no dose adjustment is required. being able to get an erection sometimes, but not every time you want to have sex. Nitrates: Administration of LEVITRA with nitrates (either regularly and/or intermittently) and nitric oxide donors is contraindicated (see CLINICAL PHARMACOLOGY, Pharmacodynamics, Effects on Blood Pressure and Heart Rate when LEVITRA is Combined with Nitrates). A 5-mg LEVITRA dose should not be exceeded when used in combination with 200 mg once daily ketoconazole. Film-coated tablet (Levitra): 10 mg administered ~60 minutes prior to sexual activity; dosing range: 5 to 20 mg; taken as one single dose and not taken more than once daily; maximum 20 mg daily. The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs). Physicians should inform their patients that concomitant use of LEVITRA with alpha-blockers is contraindicated because co-administration can produce hypotension (e.g. Men of 65 years and more are advised to take lower dose compared to those younger than them. The patient population included men aged 40-80 years with stable exercise-induced angina documented by at least one of the following: 1) prior history of MI, CABG, PTCA, or stenting (not within 6 months); 2) positive coronary angiogram showing at least 60% narrowing of the diameter of at least one major coronary artery; or 3) a positive stress echocardiogram or stress nuclear perfusion study. Geriatrics: In a healthy volunteer study of elderly males (> 65 years) and younger males (18 - 45 years), mean Cmax and AUC were 34% and 52% higher, respectively, in the elderly males (see PRECAUTIONS, Geriatric Use and DOSAGE AND ADMINISTRATION). In the event that an erection persists longer than 4 hours, the patient should seek immediate medical assistance. Counseling of patients about protective measures necessary to guard against sexually transmitted diseases, including the Human Immunodeficiency Virus (HIV), should be considered. Pregnancy Category B: No evidence of specific potential for teratogenicity, embryotoxicity or fetotoxicity was observed in rats and rabbits that received vardenafil at up to 18 mg/kg/day during organogenesis. Your doctor - or online doctor - will make a dosage recommendation based on your medical history. Figure 1: Plasma Vardenafil Concentration (Mean SD) Curve for a Single 20 mg LEVITRA Dose. If priapism is not treated immediately, penile tissue damage and permanent loss of potency may result. * Due to the sample size, confidence intervals may not be an accurate measure for these data. For patients using stable alpha blocker therapy: Initial dosage: take 5mg of Levitra once daily. LEVITRA significantly improved the overall per-patient rate of achieving an erection sufficient for penetration (SEP2) (47% on 10 mg and 48% on 20 mg LEVITRA compared to 22% on placebo; p <0.0001). Rape stories, Every woman on earth has fantasized about some explicit sexual fantasy that she may or may not have been too ashamed to talk about. maximum dose of one LEVITRA 5 mg film-coated tablet should not be exceeded when used in combination with CYP3A4 inhibitors ketoconazole, itraconazole at a dose of 200 mg or below per day. But it is cheap to buy it whole then break it by yourself. To decrease the chance of adverse events in patients concomitantly taking ritonavir or indinavir, which are strong inhibitors of CYP3A4 metabolism, a maximum single dose of 2.5 mg LEVITRA should not be exceeded. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. It is recommended to take vardenafil 60 minutes before sex. LEVITRA demonstrated a clinically meaningful and statistically significant increase in the overall per-patient rate of maintenance of erection to successful intercourse (SEP3) (49% on 10 mg, 54% on 20 mg LEVITRA compared to 23% on placebo; p< 0.0001). Patients should be counseled that concomitant use of LEVITRA with nitrates could cause blood pressure to suddenly drop to an unsafe level, resulting in dizziness, syncope, or even heart attack or stroke. In addition to the active ingredient, vardenafil HCl, each tablet contains microcrystalline cellulose, crospovidone, colloidal silicon dioxide, magnesium stearate, hypromellose, polyethylene glycol, titanium dioxide, yellow ferric oxide, and red ferric oxide. The 80 mg dose of LEVITRA (four times the highest recommended dose) was chosen because this dose yields plasma concentrations covering those observed upon co-administration of a low-dose of LEVITRA (5 mg) and 600 mg BID of ritonavir. No single correction method is known to be more valid than the other. In those patients who are stable on alpha-blocker therapy, LEVITRA should be initiated at the lowest recommended starting dose (see DOSAGE and ADMINISTRATION). Back pain was reported in 2.0% of patients treated with LEVITRA and 1.7% of patients on placebo. Max: 1 dose/day and 20 mg/dose. Vardenafil is a PDE5 inhibitor. Two foodeffect studies were conducted which showed that high-fat meals caused a reduction in Cmax by 18%-50%. In those patients who are stable on alpha-blocker therapy, LEVITRA should be initiated at a dose of 5 mg (2.5 mg when used concomitantly with certain CYP3A4 inhibitors - see Drug Interactions). Erectile dysfunction (ED) is often a symptom . The doses of LEVITRA in these studies were 5 mg, 10 mg, and 20 mg. Two of these trials were conducted in the general ED population and two in special ED populations (one in patients with diabetes mellitus and one in post-prostatectomy patients). For most patients, the starting dose of vardenafil is 10mg once per day. These effects were not observed when LEVITRA 20 mg was taken 24 hours before the NTG. This metabolite shows a phosphodiesterase selectivity profile similar to that of vardenafil and an in vitro inhibitory potency for PDE5 28% of that of vardenafil. Ritonavir (600 mg b.i.d.) Based on the results of the pre- and postnatal study, the developmental NOAEL is less than 1 mg/kg/day. Continue with Recommended Cookies. Phosphodiesterase Type 5 (PDE5) inhibitors, including LEVITRA, and alpha-adrenergic blocking agents are both vasosdilators with blood-pressure lowering effects. Following a single oral dose of 20 mg vardenafil in healthy volunteers, a mean of 0.00018% of the administered dose was obtained in semen 1.5 hours after dosing. Three patients reported dizziness following vardenafil 20 mg. Consequently, it is recommended not to exceed a single 2.5 mg LEVITRA dose in a 72-hour period when used in combination with ritonavir (see WARNINGS and DOSAGE AND ADMINISTRATION). General: Physicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. Feeling as if you can collapse or light headed. Figure 6: Mean change from baseline in standing systolic blood pressure (mmHg) over 6 hour interval following simultaneous or 6 hr separation administration of vardenafil 10 mg, vardenafil 20 mg or placebo with terazosin (10 mg) in healthy volunteers, Figure 7: Mean change from baseline in standing systolic blood pressure (mmHg) over 6 hour interval following simultaneous or 6 hr separation administration of vardenafil 10 mg, vardenafil 20 mg or placebo with tamsulosin (0.4 mg) in healthy volunteers. Nitrates: The blood pressure lowering effects of sublingual nitrates (0.4 mg) taken 1 and 4 hours after vardenafil and increases in heart rate when taken at 1, 4 and 8 hours were potentiated by a 20 mg dose of LEVITRA in healthy middle-aged subjects. The European trial showed comparable efficacy. Maximum observed plasma concentrations after a single 20 mg dose in healthy volunteers are usually reached between 30 minutes and 2 hours (median 60 minutes) after oral dosing in the fasted. [1] [2] It is a PDE5 inhibitor. The inhibitory effect of vardenafil is more selective on PDE5 than for other known phosphodiesterases (>15-fold relative to PDE6, >130-fold relative to PDE1, >300-fold relative to PDE11, and >1,000-fold relative to PDE2, 3, 4, 7, 8, 9, and 10). Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure in patients taking a PDE5 inhibitor. In those patients already taking an optimized dose of PDE5 inhibitor, alpha-blocker therapy should be initiated at the lowest dose. The maximum dose in patients with moderate hepatic impairment should not exceed 10 mg. LEVITRA has not been evaluated in patients with severe hepatic impairment (Child-Pugh C) (see CLINICAL PHARMACOLOGY, Metabolism and Excretion, WARNINGS and PRECAUTIONS). Blocked nose is a common side effect of levitra. The recommended starting dose of vardenafil for most people is 10 mg taken about an hour before sexual activity. When it comes down to it, there is no reliable "Am I Gay test", so the only way, Sometimes a woman may have been in a heterosexual relationship for years and yet feel something is somehow "off;" and she may find herself asking, "Is my husband gay?" Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision, including permanent loss of vision, that has been reported rarely post-marketing in temporal association with the use of all PDE5 inhibitors. The maximum dose of LEVITRA for which human data are available is a single 120 mg dose administered to healthy male volunteers. You can purchase Levitra at any amount from 2.5mg to 20mg. Elderly males age 65 years and older have higher vardenafil plasma concentrations than younger males (18 - 45 years), mean Cmax and AUC were 34% and 52% higher, respectively (see CLINICAL PHARMACOLOGY, Pharmacokinetics in Special Populations, and DOSAGE AND ADMINISTRATION). Read for more information. You can increase the dose to 20mg or lower it to 5mg depending with tolerability and efficacy. First Dose: take 10mg of Levitra once per day orally or as needed, 60minutes prior to sexual intercourse. The interaction is a consequence of blocking hepatic metabolism of vardenafil by ritonavir, a highly potent CYP3A4 inhibitor, which also inhibits CYP2C9. Vardenafil has not been administered to patients with bleeding disorders or significant active peptic ulceration. * Active control (drug known to prolong QT).

Levitra may cause serious side effects including: hives, difficulty breathing, swelling of your face, lips, tongue, or throat, Based on plasma exposures in the rat developmental toxicity study, 1mg/kg/day in the pregnant rat is estimated to produce total AUC values for unbound vardenafil and its major metabolite comparable to the human AUC at the MRHD of 20 mg. Levitra 10 mg tablet. Whether it's your girlfriend or your wife, this top ten. The dose of the film-coated tablets may be increased to a maximum of 20 mg or decreased to 5 mg, depending on the effectiveness of treatment and any side effects. Congenital or Acquired QT Prolongation: In a study of the effect of LEVITRA on QT interval in 59 healthy males (see CLINICAL PHARMACOLOGY, Electrophysiology), therapeutic (10 mg) and supratherapeutic (80 mg) doses of LEVITRA and the active control moxifloxacin (400 mg) produced similar increases in QTc interval. Renal Insufficiency: In volunteers with mild renal impairment (CLcr = 50-80 ml/min), the pharmacokinetics of vardenafil were similar to those observed in a control group with normal renal function. Signs You Are Gay, Is My Husband Gay? For alpha-blockers, caution is advised when PDE5 inhibitors, including LEVITRA, are used concomitantly with alpha-blockers because of the potential for an additive effect on blood pressure. Other Drug Interactions: No pharmacokinetic interactions were observed between vardenafil and the following drugs: glyburide, warfarin, digoxin, Maalox, and ranitidine. Other interactions: LEVITRA had no effect on the pharmacodynamics of glyburide (glucose and insulin concentrations) and warfarin (prothrombin time or other pharmacodynamic parameters). Consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate pathway, PDE5 inhibitors may potentiate the hypotensive effects of nitrates. [1] It is taken by mouth. It is recommended not to exceed a single 5 mg dose of LEVITRA in a 24-hour period when used in combination with erythromycin. This study, however, was not designed to make direct statistical comparisons between the drugs or the dose levels. It is recommended not to exceed a single 2.5 mg LEVITRA dose in a 24-hour period when used in combination with indinavir (see WARNINGS and DOSAGE AND ADMINISTRATION). ChildrenUse is not recommended. The maximum dose in patients with moderate hepatic impairment should not exceed 10 mg. (2.3, 8.6) ---------------------DOSAGE FORMS AND STRENGTHS---------------------- LEVITRA tablets 10 mg, 20 mg (3) -------------------------------CONTRAINDICATIONS------------------------------ LEVITRA is formulated as orange, round, film-coated tablets with "BAYER" cross debossed on one side and "2.5", "5", "10", and "20" on the other side corresponding to 2.5 mg, 5 mg, 10 mg, and 20 mg of vardenafil, respectively. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. Indinavir (800 mg t.i.d.) Effects on Exercise Treadmill Test in Patients with Coronary Artery Disease (CAD): In two independent trials that assessed 10 mg (n=41) and 20 mg (n=39) vardenafil, respectively, vardenafil did not alter the total treadmill exercise time compared to placebo.
