Getting erectile dysfunction medication requires a prescription in the United States. No oral ED drugs are available over the counter, so you’ll need to see a healthcare provider, either in person or through a telehealth platform. The process is straightforward and often takes less than a day from consultation to pharmacy pickup or delivery.
What Happens at the Appointment
A provider will ask about your medical history, sexual history, and any medications you currently take. This isn’t just a formality. ED is considered a risk marker for underlying cardiovascular disease, diabetes, and other conditions, so your doctor is screening for bigger health issues at the same time. You’ll likely have a physical exam and some basic blood work, including a morning testosterone level, blood sugar, and markers for heart disease. A urine test may also be ordered.
If your results point to a treatable underlying cause, like low testosterone or uncontrolled diabetes, addressing that condition may improve erectile function on its own. In most cases, though, a provider will also discuss oral medication as a first-line option.
The Four Main Oral Medications
All four FDA-approved oral ED drugs work the same way: they increase blood flow to the penis by relaxing smooth muscle in the blood vessels. The differences come down to how quickly they kick in and how long they last.
- Sildenafil (Viagra): The most widely recognized option. It has a half-life of about 4 hours, meaning it works best within a few-hour window after taking it. Typically taken 30 to 60 minutes before sex.
- Tadalafil (Cialis): Has a half-life of 17.5 hours, making it the longest-lasting option. Some people take it daily at a low dose so they don’t have to plan around a pill. Others take a higher dose as needed.
- Vardenafil (Levitra): Similar to sildenafil with a half-life of 4 to 6 hours.
- Avanafil (Stendra): The newest of the four, designed for faster onset.
Your provider will typically start you at a moderate dose and adjust up or down based on how well it works and whether you experience side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. These are generally mild and tend to decrease with continued use.
Who Cannot Take These Medications
The most important safety rule: you cannot use any of these drugs if you take nitrate medications. Nitrates are prescribed for chest pain (angina) and come in forms like nitroglycerin tablets, patches, or sprays. Combining a nitrate with an ED pill can cause a dangerous, sudden drop in blood pressure. The American Heart Association recommends waiting at least 24 hours after a short-acting ED pill and 48 hours after tadalafil before taking any nitrate.
People with severe kidney or liver disease are generally advised against these medications because the drugs are processed more slowly in those conditions. If you have mild to moderate kidney or liver problems, or a spinal cord injury, your provider may start with a lower dose and monitor closely.
Getting a Prescription Through Telehealth
If you’d rather skip the waiting room, telehealth platforms offer a legitimate alternative. Services like Ro (Roman), Hims, and PlushCare connect you with licensed providers who can evaluate your symptoms and prescribe medication online. You’ll fill out a detailed health questionnaire, and in many cases, a provider will follow up with a video or phone consultation.
Federal telemedicine rules currently allow providers to prescribe medications, including ED drugs, without a prior in-person visit. These flexibilities have been extended through at least the end of 2026. The medication is then either shipped directly to you or sent to a pharmacy for pickup.
One advantage of telehealth is speed. Many platforms can get you a prescription within hours. The trade-off is that you won’t get the blood work or physical exam that an in-person visit provides, which means an underlying condition like low testosterone or early heart disease could go undetected. If you haven’t had a checkup recently, an in-person visit is worth the extra effort.
What ED Medication Costs
Cost varies enormously depending on whether you choose brand-name or generic, and where you buy it. Generic sildenafil and tadalafil are significantly cheaper than their brand-name counterparts (Viagra and Cialis).
At a standard retail pharmacy, 30 tablets of generic tadalafil can run around $240 per month at full price. But pharmacy discount programs and coupons bring that number down dramatically. Some coupon services list 30 tablets of 5mg tadalafil for under $8. Through telehealth platforms, generic tadalafil starts around $8 to $11 per dose depending on the strength and whether you’re taking it daily or as needed. Brand-name Cialis through the same platforms can run $17 to $70 per dose.
PlushCare lists 30 generic tadalafil pills at about $100, compared to $400 for 30 brand-name Cialis pills. Shopping around, and always asking for the generic, makes a significant difference.
Insurance and Medicare Coverage
Private insurance coverage for ED medication is inconsistent. Some plans cover generics with a copay, while others exclude ED drugs entirely or require prior authorization. It’s worth calling your insurer before filling the prescription.
Medicare Part D does not cover ED drugs when prescribed for erectile dysfunction. This exclusion has been in place since 2007 under federal law. The same medications are covered under Part D only when prescribed for a different FDA-approved condition, such as pulmonary hypertension. If you’re on Medicare, you’ll be paying out of pocket, which makes generic options and discount coupons especially important.
Non-Pill Options
If oral medications don’t work or you can’t take them due to a contraindication, there are alternatives. The most common is alprostadil, a medication that works by directly relaxing blood vessel tissue in the penis. It comes in two forms: an injection administered with a small needle into the side of the penis, or a tiny pellet inserted into the urethral opening.
The injection produces an erection within 5 to 20 minutes, and the pellet works within 5 to 10 minutes. Erections typically last 30 to 60 minutes. Your doctor will administer the first dose in the office to find the right amount, then train you to use it at home. Injections are limited to three times per week with at least 24 hours between uses. The pellet can be used up to twice in a 24-hour period.
These options sound more involved than swallowing a pill, and they are. But for men who don’t respond to oral medication or who take nitrates for heart conditions, they provide a reliable alternative.
Avoiding Unsafe Products
A quick internet search will turn up countless “male enhancement” supplements and pills sold without a prescription. The FDA maintains a running list of these products that have been found to contain hidden, undeclared drug ingredients. Many are marketed as natural or herbal but are spiked with the same active compounds found in prescription ED drugs, sometimes at unpredictable doses and sometimes mixed with other dangerous substances.
The FDA’s published list covers only a small fraction of contaminated products on the market. If a product isn’t on the list, that doesn’t mean it’s safe. Any product claiming to treat ED without a prescription is either ineffective or illegally adulterated. The only reliable path is through a licensed provider and a licensed pharmacy.
