frequently asked questions.

Yes. Sildenafil, tadalafil and similar medications are prescription-only in the United States. Every provider listed here requires a medical consultation with a licensed clinician, who decides whether treatment is appropriate for you.

Yes, when it is provided by licensed clinicians and dispensed by licensed pharmacies in your state. Avoid any website that offers prescription medication without a consultation.

You usually complete a medical questionnaire about your health history, current medications and symptoms. A licensed provider reviews it, may ask follow-up questions, and issues a prescription only if it is safe and appropriate.

It depends on the medicine. Most are taken around 30 to 60 minutes beforehand, some can work in as little as 15 to 30 minutes, and low-dose daily tadalafil is taken at the same time every day regardless of timing. Follow the instructions from your prescriber.

Both are PDE5 inhibitors. Sildenafil is typically taken shortly before sexual activity and lasts several hours, while tadalafil lasts longer and is also available as a low daily dose. Your clinician will recommend what suits you.

No. ED medications can interact with nitrates, some blood pressure medicines and other drugs, and may not be suitable for people with certain heart, liver or kidney conditions. Always share your full medical history with the prescribing clinician.

Not without medical advice. Taking two ED medicines together, or more than one dose in 24 hours, increases the risk of side effects such as low blood pressure. Ask your clinician before combining any treatments.

There are no FDA-approved over-the-counter pills for ED. One topical gel has been authorised for over-the-counter use, and vacuum devices are available without a prescription. Be wary of "male enhancement" supplements: the FDA has found many contain hidden prescription drugs.

Many telehealth services do not accept insurance and instead offer low-cost generics or subscription plans. Some platforms and pharmacies can work with insurance. Check each provider’s pricing page and compare the total cost, including visit fees.

Yes. Stress, anxiety, depression and relationship issues are common causes, alone or alongside physical factors. ED that happens only in some situations can point to a psychological cause. Medication may still help, and counselling or sex therapy is often very effective.
