Your clinician may prescribe a type of oral medication called a PDE5 inhibitor. These ED medications include sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra).

Please note: This information is for general reference only. Your clinician will review your symptoms and health history to determine which (if any) erectile dysfunction treatments are medically appropriate.

Your clinician will consider your health history and personal preferences when prescribing treatment. The most effective medication for ED will be the one that fits your lifestyle and has the best safety profile for your unique body.

When taking ED medication, it's important to follow dispensing directions if you want the drugs to work as designed. Studies have shown that in most cases where men weren't satisfied with sildenafil (Viagra), they were taking their medication incorrectly.

Sildenafil (Viagra) and vardenafil (Levitra) are as-needed medications that you take about an hour before you plan to have sex. Clinicians recommend taking them on an empty stomach.

Tadalafil (Cialis) is the only ED medication that can be taken both as-needed and daily, in a lower dose, so it stays in your system longer. As a daily pill, it can allow for more sexual spontaneity. It may be taken with or without food.

Avanafil (Stendra) is a less commonly prescribed PDE5 inhibitor. It works faster than the other as-needed medications, but isn't available in generic form. This may make avanafil treatment more expensive.

If your clinician determines that PDE5 inhibitors are right for you, they'll take your lifestyle, preferences, and health history into account when writing your remote prescription. A monthly supply of medication will vary depending on the customer and the medication.

Daily tadalafil (Cialis) prescriptions can be written as a 30-day supply of 30 tablets plus refills.

As-needed prescriptions for tadalafil, sildenafil, or vardenafil can be written as a certain number of tablets per month plus refills. Your prescribing clinician may consider how often you plan to use the medication.

If you run out of refills, you'll need to request a new prescription, which will require another ED consultation to make sure your medication doesn't need to be adjusted.

The cost of ED medications can vary widely, especially between the generic version of a drug and the more expensive brand-name version. Your clinician will prescribe the generic version of a PDE5 inhibitor medication (sildenafil, tadalafil, vardenafil) unless you specifically request the brand (Viagra, Cialis, Levitra). Your electronic ED prescription will then be sent to the pharmacy of your choice for purchase.

Clinical research has described PDE5 inhibitors like sildenafil (Viagra) and tadalafil (Cialis) as "revolutionary" for the treatment of ED. Why? These medications have a 60-70% success rate, they work fast, and they have an established safety profile.

If you've already tried one type of PDE5 without success, studies suggest that you should 1) make sure you're following the directions on the prescription label, and then 2) be willing to try a different PDE5. Nearly 90% of men who've been treated with all three ED drugs at different times report improvements in their erections.

Research shows that 80% of erectile dysfunction cases have an organic cause. For example, erectile dysfunction can be a sign of underlying cardiovascular issues. It can also be a normal part of aging or a side effect of certain medications, like SSRIs. ED risk factors also include obesity, smoking, alcohol use, anxiety, and depression.

Yes. Your clinician needs to know your blood pressure to provide a medically appropriate treatment plan for erectile dysfunction. If you've gotten a blood pressure reading within the last 12 months, you can use that. To get a new blood pressure reading, you can visit your local pharmacy or primary care doctor, or use a home blood pressure monitor.

Yes. For premature ejaculation treatment, you can start a visit from Amazon Clinic's premature ejaculation treatment page.

What's the difference between the conditions? Premature ejaculation is when men ejaculate too early, while erectile dysfunction (ED) is when men have trouble maintaining an erection.

Erectile dysfunction and premature ejaculation can occur at the same time. If you're experiencing both conditions, clinicians generally recommend that you seek treatment for ED first before adding premature ejaculation treatments.

No. You can't get testosterone testing or treatment through Amazon Clinic at this time. If you have symptoms of low testosterone, like low libido, see your primary care provider before you start an Amazon Clinic visit.
