ED medication: what works, what’s safe, and where to buy

Having trouble with erections is common, and the good news is there are reliable medicines that help. This page breaks down the main drugs, how fast they work, basic doses, common side effects, and smart ways to buy them—so you can make safer choices without the guesswork.

How ED meds differ

The main class of ED drugs are PDE5 inhibitors. They boost blood flow to the penis after sexual stimulation. Here’s a quick snapshot:

- Sildenafil (Viagra): usually works in 30–60 minutes. Typical dose 25–100 mg. Can cause headache, flushing, or a temporary blue tint to vision for some people.

- Tadalafil (Cialis): can work within 30 minutes but lasts up to 36 hours. Common doses are 5–20 mg. Often chosen for longer windows of opportunity.

- Vardenafil (Levitra): starts around 30–60 minutes, doses 5–20 mg. Side effects are similar to sildenafil. We have a dedicated post on getting good Levitra deals and dosage tips.

- Avanafil (Stendra): faster for many, sometimes 15–30 minutes. Doses usually 50–200 mg. Fewer people report visual side effects.

Which one to try first depends on how often you want sex, how soon you need it to work, and how you handle side effects. If you’re unsure, talk to your doctor—start low and adjust.

Safety, interactions, and buying tips

Safety first: never mix PDE5 inhibitors with nitrates (often found in chest pain meds). That combo can cause a dangerous drop in blood pressure. Also be cautious if you take alpha-blockers for prostate issues, and tell your doctor about heart meds, blood pressure drugs, or liver/kidney problems.

Watch for rare but serious signs: a painful erection lasting more than 4 hours (priapism), sudden vision or hearing loss. If any of these happen, get emergency care.

Want to buy online? Use pharmacies that require a prescription, show clear contact details, and have third-party verification or licensing. Avoid sites that sell huge multi-month supplies without a prescription or pressure you to buy through chat offers. Our posts about online pharmacy alternatives and safe buying tips can help you spot legit sellers and avoid scams.

Other things that help ED: control blood sugar if you have diabetes, stop smoking, lose extra weight, cut back on heavy drinking, and check blood pressure and cholesterol. Medication often works better when combined with these changes.
