How it works
How tadalafil works
A longer-acting PDE5 inhibitor that helps more blood flow in — but it still needs a signal to get started.
The blood-flow route
Tadalafil 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.
Food flexibility
Unlike some other ED medications, tadalafil can generally be taken with or without food. A heavy meal doesn't meaningfully slow its absorption the way it can with sildenafil.
Timing and response still vary from person to person.
Treatment decisions are made by a licensed provider after reviewing your individual health profile.
Timing & duration
A longer window, less clock-watching.
Tadalafil's longer duration means you don't have to time it as precisely before the moment. Here's what the labeling and clinical experience describe.
30 min – 2 hrs
Typical onset
May begin working as soon as 30 minutes after taking it, though it can take up to about 2 hours for some people.
Up to 36 hrs
Duration of effect
Tadalafil can stay effective for up to about 36 hours — which is why it is sometimes called a long-lasting ED medication.
With or without food
Food interaction
Tadalafil can generally be taken with or without food, unlike some shorter-acting options.
Sexual stimulation is still required — tadalafil does not cause an erection on its own. Your provider will explain what to expect from the strength and schedule they recommend.
Important safety
Who should not take tadalafil
Tadalafil isn't for everyone. The nitrate warning comes first — always tell your provider about every medication you take.
Nitrates (any form)
Tadalafil 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
Tadalafil 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 tadalafil 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 tadalafil is medically appropriate.

FAQ
Questions about tadalafil.
Tadalafil starts at $39/month for a 6-tablet plan. 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. Surfbound offers tadalafil in a single 20 mg strength, selected by a licensed provider.
Yes. Tadalafil 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.
Surfbound offers tadalafil as a 20 mg oral tablet. It is a single strength. You do not choose your own dose or how often to take it — a licensed provider reviews your health history and decides whether tadalafil 20 mg is appropriate for you.
Tadalafil may begin working within about 30 minutes to 2 hours after taking it. Its effects can last up to about 36 hours, which is why it is sometimes described as a long-lasting ED medication. Sexual stimulation is still required — it does not cause an erection on its own. Unlike some other ED medications, tadalafil can generally be taken with or without food.
Surfbound offers 6, 12, or 18 tadalafil tablets per month. The quantity is a supply option you can select at checkout, but the 20 mg strength and how often you take it remain a provider decision. Choose the monthly quantity that matches your expected use.
No. Tadalafil is contraindicated in anyone taking nitrates (such as nitroglycerin) in any form, because the combination can cause a serious, sometimes life-threatening 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, indigestion, and back or muscle pain. Rarely, it can cause priapism — an erection lasting more than four hours, which is a medical emergency — or sudden vision or hearing changes. A provider reviews your history to help decide whether it is appropriate for you.
The active ingredient, tadalafil, is FDA-approved in its brand-name form. Surfbound’s tadalafil 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.
