If you want a pill that can help you get an erection quickly, prescription PDE5 medicines are the main options to discuss with a clinician. Avanafil may be taken about 15 minutes before sex, sildenafil usually takes about 30 minutes to start working, tadalafil is often taken about 30 minutes before sex and may last up to 36 hours, and vardenafil may begin in about 30 to 60 minutes. The best fit depends on how soon you want it to work, how long you want the window to last, your other medicines, and your health history.

Which pill works fastest for an erection?
Avanafil is the quickest oral option described in the available information: it is taken about 15 minutes before sex. Sildenafil is commonly taken about an hour before sex and may begin working in about 30 minutes. NYU Langone lists sildenafil, tadalafil, and vardenafil as prescription oral options that are generally taken 30 to 60 minutes before sexual activity and work by improving blood flow during arousal.
| Option | When it may be taken | How long it may last | Key point |
|---|---|---|---|
| Avanafil | About 15 minutes before sex | Not specified here | A faster oral timing option. |
| Sildenafil (Viagra) | About 30 to 60 minutes before sex | About 1 to 4 hours | Generic versions can be a lower-cost option. |
| Tadalafil (Cialis) | About 30 minutes before sex, or a lower daily dose | Up to 36 hours at a higher as-needed dose | Useful if you want a longer window rather than one planned time. |
| Vardenafil | About 30 to 60 minutes before sex | About 5 to 7 hours | Available as a tablet and, in one form, a dissolving tablet. |
These medicines support the body’s normal response to sexual arousal. They limit PDE5, an enzyme that can restrict blood flow; that helps nitric oxide relax muscle in the penis and lets more blood flow in during arousal. NYU Langone explains that oral medicines improve blood flow to the penis during arousal, and the NCBI PDE5 overview explains this drug class and its role in erectile dysfunction.
Is Cialis better than Viagra for older men?
There is no single best choice based on age alone. For many men, the practical difference is timing: sildenafil is a shorter, as-needed option, while tadalafil can provide a longer window and also has a lower-dose daily schedule. If you are 70 or older, ask a clinician which starting plan fits your medications, blood pressure, kidney or liver health, and how often you expect to have sex.
If your goal is a long window for intimacy, tadalafil is the option in this comparison that may work for up to 36 hours. That does not mean an erection should last for 36 hours. If an erection lasts more than four hours, NYU Langone says to seek emergency care.
Why might an ED pill not be working?
An ED pill needs sexual arousal to help produce an erection. Timing can matter, and the medicine may not be the right option or dose for your situation. NYU Langone notes that about 35% of men do not respond to oral ED medicines; prescription alternatives include intraurethral medication and penile injections.
If a service such as BlueChew is not giving you the result you expected, confirm the active ingredient, dose, timing instructions, and every medicine or supplement you take with its prescriber. Do not increase a dose on your own. ED can also be connected with diabetes, heart disease, hormonal factors, stress, anxiety, medication effects, or other factors, so a clinician can help identify what is getting in the way.
What side effects should you expect?
There is no ED medicine with zero possible side effects. The common effects differ by medicine, so the right question is which option fits your health profile and which effects you are willing to discuss with a prescriber.
| Option | Common effects described | What to keep in mind |
|---|---|---|
| Avanafil | Headache, flushing, stuffy or runny nose, back pain, sore throat | It may act quickly, but it still has important medicine interactions. |
| Sildenafil | Flushing, upset stomach, muscle aches, vision changes | Generic sildenafil may make this familiar option more affordable. |
| Tadalafil | Limb pain | Its longer duration is the main practical difference. |
| Vardenafil | Dizziness | It is another prescription PDE5 option with a shorter window than tadalafil. |
Do not combine a PDE5 medicine with nitrates used for heart disease, such as nitroglycerin or isosorbide medicines. That combination can cause a severe drop in blood pressure. This is one of the most important questions to settle with a clinician or pharmacist before ordering.
Are instant erection pills sold over the counter a good option?
No oral pill is presented in the available information as an FDA-approved over-the-counter ED medicine. Supplements marketed as “natural” may have inconsistent labels, may interact with medicines, and may include hidden drug ingredients. The FDA has warned about sexual-enhancement products with hidden drug ingredients, which matters especially if you use nitrate medicines or medicines for blood pressure.
For a closer look at this shopping problem, read Instant Erection Pills and FDA Warnings. If you are considering a supplement such as L-arginine or L-citrulline, those ingredients support nitric oxide production, but they are not an instant substitute for a prescription ED medicine. L-arginine may lower blood pressure and can cause nausea, abdominal pain, diarrhea, or bloating.
What about salt tricks, Vicks, and “all-night” pills?
Do not let a viral tip replace a clear medication check. The useful details are the active ingredient, the dose, when to take it, how long it may last, and whether it fits your medicines. A product that promises an erection all night is not describing the normal goal of ED treatment; a prolonged erection needs urgent care.

How do you choose the right option?
Choose based on your real need, not the boldest ad. If speed is your priority, ask about avanafil. If you want a familiar as-needed medicine with generic availability, ask about sildenafil. If you want a longer window or a daily option, ask about tadalafil. If oral medicines have not helped, ask what other prescription approaches may suit you.
Before you order
- Ask which active ingredient and dose fit your health history.
- Ask whether any current medicine, especially nitrates, blood-pressure medicine, or an alpha-blocker, changes your options.
- Ask how long the medicine may take to work and how long its effect window may last.
- Ask what to do if you develop troublesome side effects or an erection lasting more than four hours.
- Ask whether an ongoing erection problem could be connected with diabetes, heart health, hormones, stress, sleep, or another medicine.
