About Tadalafil (Generic Cialis)

How does it work?

This medication relaxes the muscles in certain blood vessels and allows more blood to flow into specific parts of the body. It helps initiate and maintain an erection during times of intimacy.

What does it treat?

This medication treats erectile dysfunction, which occurs when the penis experiences problems getting or keeping an erection firm enough for sexual intercourse. In some cases, it’s also prescribed for benign prostatic hyperplasia, a condition in which the prostate gland becomes enlarged.

What forms does it come in?

This medication is an oral erectile dysfunction treatment that comes as a pill. Take it before sexual activity—follow your prescriber’s instructions carefully.

Tadalafil vs. Cialis

Tadalafil is the active ingredient in the brand erectile dysfunction pill Cialis. They're essentially the same medication—both help improve blood flow to the penis.

How much will it cost?

Dr. B offers online consultations for $15—which is less than most copays. If an ED prescription is appropriate, your out-of-pocket medication cost will depend on your insurance and where you decide to get your prescription filled.

How do you take this medication?

Tadalafil is usually taken as needed, so you don't have to worry about missing a dose. In most cases, it’s best to avoid taking more than one dose in a day—talk to your licensed provider for details.

What happens if I miss a dose?

It's generally not a big problem, especially when Tadalafil is taken “as needed” (not on a regular dosing schedule) prior to intimacy (before sexual activity). Do not take two doses of Tadalafil at the same time to make up for the missed dose.

It is important to note that tadalafil can stay in your system for up to 36 hours, so even if you miss a dose, you may still be able to get and keep an erection.

Also, remember not to take more than one dose of Tadalafil within a 24-hour period, as taking too much of this medication can increase the chances of experiencing side effects. It’s best to follow your healthcare provider’s instructions to avoid side effects.

What happens if I take too much?

Taking too much of this medication can increase the chances of side effects like headaches, dizziness and low blood pressure.

If you’ve taken too much, contact your health provider or local poison control center (800-222-1222) immediately.

Can I get Tadalafil (Generic Cialis) online?

Yes! With a discreet online consultation from Dr. B, a licensed medical provider will review your treatment. If appropriate, they will send an online prescription or refill to your pharmacy of choice.
