Taking ED medication for the first time: what to expect

By the Rushmore Team · Updated August 2026

You've got the prescription. Now what? Most first-timers have the same unspoken questions — will it feel weird, will it be obvious, what if it doesn't work — and almost nobody asks them out loud. Here are the answers.

What it does (and doesn't do)

First, the biggest misconception: PDE5 inhibitors like sildenafil and tadalafil don't cause erections. They make erections easier to get and keep when you're aroused. You won't sit at dinner fighting off an unwanted situation. No arousal, no effect — which also means the medication working depends on you actually being in the mood, relaxed, and engaged. It amplifies desire's effects; it doesn't replace desire.

Timing and practicalities

• Give it time to absorb. Sildenafil typically needs 30–60 minutes; tadalafil 1–2 hours. Taking it and immediately expecting results is the most common first-timer mistake.
• Watch the heavy meal. A big, fatty dinner can noticeably delay sildenafil. Tadalafil is less picky. Details in our comparison.
• Go very easy on alcohol. A drink is fine for most men; several drinks work directly against the medication — alcohol has its own plans.
• Follow your prescribed dose exactly. More is not better; it just means more side effects. Never double up because round one underwhelmed.

If the first time isn't perfect

Here's what the pamphlets undersell: the first attempt is a bad test. You're evaluating a medication while also being nervous about evaluating a medication — and anxiety is itself an erection-killer. Doctors commonly tell patients to try a medication on several separate occasions before judging it. Many men who report "it didn't work" after one try report success once the novelty and nerves wear off. Give it a fair trial, and report back to your provider rather than giving up.

Side effects: what's normal, what's not

The common ones are minor and pass on their own: headache, facial flushing, stuffy nose, mild indigestion. They're byproducts of the same blood-vessel relaxation that makes the medication work.

The rare ones you should know cold: an erection lasting more than four hours (priapism) is a medical emergency — go to an ER, it's treatable but time-sensitive. Sudden vision or hearing changes: stop the medication and seek care. And the non-negotiable rule you'll hear everywhere from us: never combine ED medication with nitrates — the blood-pressure drop can be dangerous. Your provider screens for this, which is why the health questionnaire asks about every medication you take.

The mindset that helps

Treat it like backup, not like a test you have to pass. The medication's real gift for many men is what it does to the mental game: knowing support is there often breaks the worry loop that caused trouble in the first place. Relax, take your time, and let it be unremarkable.
