Sildenafil is sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It is unclear if it is effective for treating sexual dysfunction in women. It is taken by mouth or by injection into a vein.
Your GoMDUS doctor or nurse practitioner will recommend the appropriate starting dose based on all the information you provide. Typically our doctors or nurse practitioners prescribe the 60mg as a starting dose, which means taking 3 of the 20mg pills at a time.
Never take more than one dose in 24 hours. Do not eat grapefruit or drink grapefruit juice on the same day you take sildenafil because it increases the chance of side effects.
Common side effects include headache, flushing, upset stomach, minor changes in vision, nasal congestion, back and muscle pain, nausea, mild dizziness, and rash. These side effects will often go away on their own, but you should seek treatment if they persist.

Different sildenafil strengths
If a GoMDUS doctor or nurse practitioner deems it appropriate, they may prescribe generic 20mg sildenafil tablets in doses of 1, 3, or 5 pills at a time, depending on the individual's needs. These doses (20mg, 60mg, and 100mg) are similar to the more costly 25mg, 50mg, and 100mg doses of sildenafil. A typical starting dose for those who have not taken these medications before is 60mg, which is equivalent to 3 of the 20mg tablets. Pfizer also offers a more expensive branded version of the 20mg pill called Revatio. The generic 20mg pills provide an affordable option for treating erectile dysfunction. Additionally, Pfizer offers Viagra-branded and generic versions of 25mg, 50mg and 100mg sildenafil pills.
FDA and sildenafil 20mg
The FDA has granted approval for the use of 25mg, 50mg, and 100mg sildenafil pills for the treatment of erectile dysfunction. However, the FDA has not approved the use of 20mg pills for this purpose, only for the treatment of pulmonary hypertension. Therefore, if you take 20mg pills to treat erectile dysfunction, you are using it in a manner that is not authorized by the FDA.
