Erectile Dysfunction Medication: What Works, How to Choose, and Safety Tips

ED meds can change daily life fast — better erections, less anxiety, and more confidence. If you’re looking for clear, useful facts about the main drugs, how they work, and what to watch out for, this page gets straight to the point.

Common options and how they work

The most used medicines are PDE5 inhibitors: sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra). They help erections by increasing blood flow to the penis when you’re sexually stimulated. Tadalafil lasts the longest (up to 36 hours); sildenafil and vardenafil act faster but wear off sooner. Avanafil often works quickest and may cause fewer side effects for some people.

There are also other approaches: injectable alprostadil for people who don’t respond to pills, vacuum erection devices, and hormone testing if low testosterone is suspected. Which route is right depends on your health, preferences, and how severe the ED is.

Safety, interactions, and common side effects

Never take PDE5 inhibitors with nitrates (nitroglycerin and similar drugs). That combo can dangerously drop your blood pressure. Tell your doctor about heart meds, alpha-blockers for prostate issues, and strong CYP3A4 inhibitors like some antifungals and HIV drugs — they change drug levels. Grapefruit can increase PDE5 levels too, so avoid large amounts if you take these meds.

Typical side effects are headache, flushing, nasal congestion, and upset stomach. Vision changes or sudden hearing loss are rare but serious — stop the drug and seek care if they happen. An erection lasting more than four hours (priapism) is a medical emergency — get immediate help.

Older age, kidney or liver disease, and some heart conditions mean dosage adjustments or different choices. Start low, follow your prescriber’s advice, and have a brief check-in after the first dose to make sure everything’s okay.

Thinking about buying ED meds online? Only use licensed pharmacies that require a prescription and show contact info. Avoid unnamed sellers, very cheap pills, or products that don’t list ingredients. Counterfeit meds are common and risky.

Lifestyle matters too. Cutting excess alcohol, losing weight, quitting smoking, improving sleep, and managing stress or diabetes often improve erectile function and make meds work better. If you have relationship concerns or anxiety about sex, talking to a therapist or couples counselor can help alongside medication.

If you’re unsure which option suits you, a short chat with your primary care doctor or urologist clears things up faster than guessing. A proper check keeps you safe and helps pick the simplest, most effective route for your life.
