How do you get sildenafil in the United States?

4 min read · Reviewed

Medically reviewed by Dr. Priya Natarajan, MD - Clinical pharmacology, Dublin

A licensed US clinician writes sildenafil. A pharmacy fills that line. Brand Viagra and generic sildenafil both move on that path. The US tablet is not an over-the-counter product. Strengths on the order are 25 mg, 50 mg, and 100 mg. Online shops get checked with FDA BeSafeRx. Nitrates on the chart stop the write. One tablet a day is the frequency cap after the fill.

01Who writes the US sildenafil order?

A licensed clinician who can see the chart writes the tablet. A urologist is not required if that first clinician can do the work. The pharmacy fills the strength and product line that arrived, not a milligram a website invented.

The visit can be in a room or on a screen. Either way the same two steps close it: a licensed US clinician writes, then a pharmacy fills. See the sildenafil shelf for the 25 mg start this site highlights. Nitrates on the chart still stop that write. One tablet a day is the frequency cap after the fill. Sexual stimulation is still required once the bottle is in the house.

02Can an online shop skip the written line?

FDA BeSafeRx is how you check an online shop. A site that offers the tablet without a licensed clinician writing first fails that check. A US phone number on the homepage is not enough by itself.

Mail-order and a local pickup both wait on the same written order. The clinician who writes has to be licensed where the person sits. The bottle that arrives should match the line that was sent. Brand Viagra and generic sildenafil both use that path. The UK pharmacy product Viagra Connect 50 mg does not let a US shop skip the written line.

03Do nitrates block the write?

Nitrates on the chart stop the write. Organic nitrates and nitric oxide donors are contraindicated with Viagra. A safe interval after the last tablet has not been determined.

At 24 hours, plasma sildenafil is about 2 ng/mL against about 440 ng/mL at 1 hour. That pair is why the interval stays undetermined. It is not a green light to add a nitrate at hour 24. The 25 mg start used at 65 and older does not open that interval. A potent CYP3A4 inhibitor on the chart is a 25 mg start, not a nitrate exception.

04What strengths can that order name?

Tablet strengths on a US Viagra order are 25 mg, 50 mg, and 100 mg. Most labelled starts sit at 50 mg about 1 hour before sexual activity. This shelf highlights 25 mg for age 65 and older, hepatic impairment, severe renal impairment, and a potent CYP3A4 inhibitor.

Ritonavir holds 25 mg and does not repeat inside 48 hours. The pharmacy fills the milligram on the line. It does not pick a strength because a shop page showed a different tablet. The labelled start for most men is still 50 mg about 1 hour before sexual activity. Stimulation is still required after that hour.

05Is Viagra over the counter at a US counter?

United States counters do not sell Viagra without a written order. The UK has a pharmacy product, Viagra Connect 50 mg. That UK supply is not an FDA over-the-counter approval. The US path stays clinician then pharmacy.

The full OTC question lives on whether you can buy Viagra over the counter in the US. Strengths on a US order stay 25 mg, 50 mg, and 100 mg. FDA BeSafeRx is still the check if the shop is online. A high-fat meal can still delay the peak about 60 minutes after a lawful fill.

06After the fill, is one tablet a day the cap?

Once the bottle is filled, the frequency cap is one tablet a day. Sexual stimulation is still required. A high-fat meal can delay the peak about 60 minutes. Those lines travel with the bottle, not with the shop that shipped it.

Generic sildenafil uses the same write-then-fill path. The first US generic Viagra arrived from Teva on December 11, 2017, in 25 mg, 50 mg, and 100 mg. That history sits on whether there is a generic for Viagra. Nitrates still stop the write on a generic line. Ritonavir still holds 25 mg and does not repeat inside 48 hours.

Before you start, stop, or change any medicine, speak with your prescriber or pharmacist. They hold your chart. This bin card does not. Open the bin disclaimer.

Eli asks

Can my regular clinician write this, or only a urologist?

A licensed clinician who can see the chart can write sildenafil. A urology referral happens when that first clinician wants a second look. Nitrates on the chart still stop the write. The pharmacy fills 25 mg, 50 mg, or 100 mg as written.

Gio asks

If the shop looks American, is BeSafeRx optional?

BeSafeRx is the FDA check for online shops. A US-looking page that skips the written order still fails that check. Mail-order and a local pickup both wait on the same written line.

Ivo asks

Can the pharmacy fill 25 mg if the visit said 50?

The pharmacy fills the line that arrived. Most starts are 50 mg. Twenty-five milligrams is the start considered at 65 and older, with hepatic or severe renal impairment, or with a potent CYP3A4 inhibitor. Ritonavir holds 25 mg and does not repeat inside 48 hours.
