Sildenafil

Sildenafil is the active ingredient in Viagra® and belongs to a class of medications called PDE5 inhibitors. During sexual arousal it enhances the natural signal that relaxes the smooth muscle in the penis, increasing blood flow so you can achieve and maintain an erection. It is prescribed by Revibe’s licensed healthcare providers as part of a personalized ED plan.

No. Sildenafil supports the body’s normal erection process but does not create an erection on its own sexual arousal is still required for it to work. It improves your ability to get and keep an erection in response to stimulation.

Sildenafil is typically taken about 30 to 60 minutes before sexual activity, and its effect on erections generally lasts around 4 to 6 hours. It is an as-needed (on-demand) medication rather than a daily one.

A high-fat meal can slow how quickly sildenafil is absorbed and delay its onset, so many men take it on a relatively empty stomach. Heavy alcohol use can worsen erectile function and increase side effects such as dizziness. Your Revibe Health provider will give guidance based on your situation.

Not every man responds to a first medication or dose, and dosing sometimes needs adjustment. Revibe offers other options—including tadalafil, custom-compounded formulations, intracavernosal injections, and testosterone therapy when low testosterone is a contributing cause. Your provider will help find the approach that works for you.

Yes. Sildenafil is the generic name for the medication sold under the brand name Viagra®; both contain the same active ingredient and work the same way. Revibe prescribes it as part of an evidence-based, individualized treatment plan.

The most common side effects are headache, facial flushing, nasal congestion, indigestion, and temporary visual changes such as increased light sensitivity or a bluish tint. These are usually mild and short-lived. Rare but serious effects include a sudden change in vision or hearing and a prolonged, painful erection.

Sildenafil must not be taken with nitrate medications (used for chest pain) because the combination can cause a severe, potentially dangerous drop in blood pressure. Caution is also needed with alpha-blockers and in men with certain heart conditions. This is why a provider reviews your health history and medications before prescribing.

An erection lasting longer than four hours (priapism) is a medical emergency that can damage penile tissue if untreated. Seek immediate medical care. This is uncommon but important to know before starting any ED medication.
