Tell your doctor or pharmacist if the advice on how to cope does not help or the side effects get worse. Headaches should usually go away after the first week of taking sildenafil. Talk to your doctor if they last longer than a week or are severe. Common side effects of sildenafil happen in more than 1 in 100 people.
See "Dosage adjustments" just above for details about when a lower dose might be prescribed. Physicians should inform patients not to take VIAGRA with other PDE5 inhibitors including REVATIO or other pulmonary arterial hypertension (PAH) treatments containing sildenafil. Sildenafil is also marketed as REVATIO for the treatment of PAH. The safety and efficacy of VIAGRA with other PDE5 inhibitors, including REVATIO, have not been studied [see Warnings and Precautions (5.7)]. Physicians should warn patients that prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) have been reported infrequently since market approval of VIAGRA.
Other drugs that operate by the same mechanism include tadalafil (Cialis) and vardenafil (Levitra). Consider a starting dose of 25 mg in patients treated with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, or saquinavir) or erythromycin. Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see Drug Interactions (7.4) and Clinical Pharmacology (12.3)]. Population pharmacokinetic analysis of clinical trial data indicated a reduction in sildenafil clearance when co-administered with CYP3A4 inhibitors (such as ketoconazole, erythromycin, cimetidine). Although no increased incidence of adverse events was observed in these patients, when sildenafil is administered concomitantly with CYP3A4 inhibitors, a starting dose of 25 mg should be considered. Most, but not all, of these patients had pre-existing cardiovascular risk factors.
100 mg is the maximum dosage available for Viagra and sildenafil for a reason, and your healthcare provider is unlikely to prescribe more than that for you. There are several Viagra alternatives available if you aren’t suitable for Viagra, or want something that lasts longer than 4 hours. We look at the different erectile dysfunction treatments that you can get with a prescription and over-the-counter. Viagra 50mg is the standard starting dose for most people, and is what we recommend if you’ve never tried Viagra before. 50mg is the most popular dosage of Viagra, and is effective for most men who try it. It is worth noting that any side effects experienced from tadalafil will typically last longer because the drug remains in the bloodstream significantly longer than sildenafil.
Your clinician will want to find the lowest dose of the drug that does the job. This is to help keep the likelihood of side effects as low as possible. Your sildenafil dosage may be increased to 100mg if the lower dosage has not had the desired effect. Viagra (sildenafil) is a medication for erectile dysfunction that can help you to get and keep an erection. It works by relaxing your blood vessels and increasing the blood flow to your penis.
