Meet Viagra^®

Clinically-proven to reduce ED symptoms
Flexible dosage options
Taken on an as-needed basis for satisfying sex

Always take Viagra as instructed by your healthcare provider. It’s typically taken about one hour before you plan to have sex. After about 30 minutes, its effects will kick in, and for up to four hours, you are able to get hard if you are sexually excited. If you take Viagra after a high-fat meal, it may take longer for the medicine to start working.

Common Viagra side effects

Viagra users could potentially experience flushing, headache, nausea, dizziness, chest or arm pain, and, in rare cases, changes in vision or loss of sight. Seek emergency care immediately if you have an erection that lasts longer than four hours or it becomes painful. Do not drink alcohol to excess (more than five drinks) while taking Viagra.

Prescription products require an online consultation with a physician who will determine if a prescription is appropriate.

Why Viagra^® ?

As the original prescription ED medication, Viagra’s sexual health benefits are backed by extensive scientific research.

Viagra can be taken as-needed to help men achieve optimal erectile function. It’s good for guys who don’t want to take a pill every day.

Inhibits PDE5

Viagra works by suppressing an enzyme called phosphodiesterase type 5 (PDE5).

Boosts blood flow

When PDE5 is suppressed, blood is able to move more freely to the penis.

Gets you hard

More blood flow allows for harder, longer-lasting erections with sexual stimulation.

Frequently asked questions about Viagra

What is Viagra?

Viagra®, the branded version of sildenafil, is the first-ever prescription treatment for erectile dysfunction.

How does Viagra work?

Viagra treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.

Does Viagra make you last longer?

Viagra probably won't make you last longer in bed. No research has proven definitively that Viagra can increase how long you can have sex. If you are struggling with premature ejaculation, you may qualify for prescription sertraline or Performance Wipes from Rex MD.

How many inches does Viagra give you?

While Viagra can help you achieve an erection with sexual stimulation, it won't make your penis larger than normal.

Is Viagra available over the counter?

No. You'll need to have a prescription from your healthcare provider.

How can I get Viagra?

Rex MD makes it easy. First, go online and answer a few questions about your symptoms, lifestyle, and health history. Then, a licensed healthcare provider will review your information and prescribe ED medication, if appropriate. If approved, your medication will be delivered to your door with fast, free shipping.

Can women take Viagra?

While some research suggests this medication may benefit women with sexual dysfunction, the FDA has not approved it for use in women. In some cases, a doctor can prescribe Viagra for off-label use. Women should not take Viagra or any other prescription drug unless it's been prescribed by their doctor.

Who should not take Viagra?

Viagra is not for patients with serious heart or liver problems. It is also not for patients with low blood pressure (hypotension) and certain eye diseases. Complete your free online consultation today to see if Viagra is right for you.

What does Viagra look like?

Branded Viagra comes in a blue diamond-shaped pill. Sildenafil, the generic version of Viagra, comes in white round or oval-shaped pills.

Is Viagra safe?

Viagra is generally safe as long as you take the recommended dose and follow the instructions of your prescribing healthcare provider. Taking more than the recommended amount of Viagra increases your risk of serious side effects, such as heart problems, vision problems, or permanent damage to the penis.

Is sildenafil (generic Viagra) as effective as “name brand” Viagra?

Yes. Sildenafil works the same as Viagra, but it costs less.

How long does Viagra last?

The effects of Viagra usually last about four hours, giving you a large time frame where you can have sex with optimal erectile function.

How long does it take for Viagra to work?

The effects of Viagra typically kick in about 30 minutes after you take it. That means, you should be able to achieve an erection with sexual stimulation.
