Before you begin
What to know before you order.
Sildenafil oral tablets in 50 mg or 100 mg. A licensed provider — not you — selects the strength based on your health profile.
Choose 6, 12, or 18 tablets per month with 1-, 3-, or 12-month options. See the full plan table for exact totals.
Every plan includes a private online intake, a licensed provider review, and discreet shipping if prescribed.
You are only charged once your medication is approved. A licensed provider reviews your intake and decides whether sildenafil — and which strength — is medically appropriate for you. Orders are nonrefundable once the pharmacy has processed the item. Read the refund and cancellation policy.
50 mg vs 100 mg
What's the difference between 50 mg and 100 mg?
They're the same medication — the difference is simply how much active ingredient is in each tablet. Your provider, not you, chooses which strength fits.
50 mg
The standard starting point
- Same active ingredient, lower amount per tablet
- Often selected when a lower amount is appropriate
- Provider decides based on your health profile
100 mg
A higher amount per tablet
- Same active ingredient, more per tablet
- Not a "stronger treatment" — simply a larger single tablet
- Provider decides whether this amount fits
You don't choose your dose. A licensed provider reviews your intake and selects the strength — if any — that is medically appropriate for you.
How it works
How sildenafil works
A PDE5 inhibitor that helps more blood flow in — but it still needs a signal to get started.
The blood-flow route
Sildenafil is a PDE5 inhibitor. It relaxes the blood vessels in the penis so more blood can flow in and stay. That's what supports and maintains an erection.
It doesn't create an erection on its own — sexual stimulation is still required.
Timing & window
Sildenafil is usually taken about 30 to 60 minutes before sexual activity. Its effects generally last for about 4 to 6 hours.
A heavy or high-fat meal can slow absorption and delay onset. Timing and response vary from person to person.
Treatment decisions are made by a licensed provider after reviewing your individual health profile.
Important safety
Who should not take sildenafil
Sildenafil isn't for everyone. Always tell your provider about every medication you take.
Nitrates (any form)
Sildenafil is contraindicated with nitrates — including nitroglycerin and other nitrate medications — because the combination can cause a serious, sometimes life-threatening drop in blood pressure. This includes regular and intermittent nitrate use.
Guanylate cyclase stimulators
Sildenafil should not be used with riociguat (a guanylate cyclase stimulator) due to the risk of dangerously low blood pressure.
Certain heart conditions
Men with certain cardiovascular conditions may not be candidates. A licensed provider reviews your cardiac history before deciding whether sildenafil is appropriate.
Priapism & vision/hearing changes
An erection lasting more than four hours (priapism) or sudden vision or hearing changes require immediate medical attention. These are rare but serious.
This is not a complete list of contraindications. A licensed provider reviews your full health history — including all prescriptions, over-the-counter products, and supplements — before deciding whether sildenafil is medically appropriate.

FAQ
Questions about sildenafil.
Sildenafil starts at $39/month for a 6-tablet plan in either 50 mg or 100 mg strength. The price depends on two things: how many tablets you take per month (6, 12, or 18) and whether you pay month-to-month or prepay for 3 or 12 months. The provider — not you — picks the strength (50 mg or 100 mg) that fits your health profile.
Yes. Sildenafil is a prescription-only medication. Through Surfbound, you complete a short online intake, then a licensed provider reviews it and decides whether treatment is medically appropriate. If it is, a prescription is written for the strength and schedule the provider selects.
Both are the same active ingredient; the 100 mg tablet simply contains more of it. A licensed provider chooses the appropriate strength based on your history and response. You do not pick your own dose — the provider decides which strength is right for you, if either is.
Sildenafil is generally taken about 30 to 60 minutes before sexual activity. Its effects usually last for about 4 to 6 hours. Sexual stimulation is still required for it to work — it does not cause an erection on its own. Taking it with a heavy or high-fat meal may delay how quickly it starts working.
No. Sildenafil is contraindicated in anyone taking nitrates (such as nitroglycerin) in any form, because the combination can cause a serious drop in blood pressure. Always tell your provider about every medication you take, including over-the-counter and recreational products that may contain nitrates.
Common side effects can include headache, flushing, nasal congestion, and indigestion. Less commonly, it can cause visual changes or, rarely, priapism — an erection lasting more than four hours, which is a medical emergency. A provider reviews your history to help decide whether it is appropriate for you.
Surfbound offers 6, 12, or 18 tablets per month. The quantity is a supply option you can select at checkout, but the strength remains a provider decision. Choose the monthly quantity that matches how often you expect to use it.
The active ingredient, sildenafil, is FDA-approved in its brand-name form. Surfbound’s sildenafil is a compounded single-ingredient tablet, and it is not FDA-approved as a finished drug product. Compounded medications are prepared by licensed pharmacies for individual patients when a provider determines treatment is appropriate.
