How treatment works

The tadalafil rundown

Stay Ready

Tadalafil is long-lasting and can be taken daily. So you’ll always be ready to perform when the mood is right. 

Stronger Erections

Tadalafil blocks an enzyme called PDE5, which makes it easier for blood to flow to the penis for a stronger, longer lasting erection. 

Long-lasting Results

Tadalafil stays in the body for 24-36 hours. During that time a person has an easier time getting and maintaining an erection. It doesn’t cause immediate arousal, so you’ll only get erect when you’re in the mood. That means when the time is right, turn up the romance.

What safety information should I know before taking tadalafil?

Do not take tadalafil if you take any medicines called nitrates, often prescribed for chest pain, or guanylate cyclase stimulators like Adempas (riociguat) as this can result in a sudden, dangerous drop in blood pressure. Learn more

Frequently asked questions about tadalafil

Tadalafil (pronounced tuh·da·luh·fil) is the active ingredient in Cialis® and generic Cialis®. It is part of a family of medicines used to treat erectile dysfunction (ED) called phosphodiesterase-5 inhibitors (PDE5i). Other drugs in this family include Viagra® (sildenafil), Levitra (vardenafil), and Stendra (avanafil). Generic Cials® (tadalafil) acts the same way in the body and are expected to produce the same effects as the original brand-namebrand name Cialis®. It comes in several different doses and can be taken either as-needed or daily for erectile dysfunction.

Compared with other ED drugs, tadalafil lasts longer, working for up to 36 hours. But that doesn’t mean a continuous erection for 36 hours. It means that the medicine enhances your ability to get hard over the course of 36 hours. You still need to be aroused to get an erection.

Tadalafil increases blood flow into the penis, giving you stronger and longer-lasting erections. This is why it’s prescribed for erectile dysfunction (ED), a condition where the penis doesn’t get enough blood because the blood flow isn’t strong enough, or their blood vessels don’t stay open long enough to get the blood into their penis. However, tadalafil and other PDE5 inhibitors won’t give you an automatic erection. You need to be aroused for them to work.

Tadalafil is used to treat erectile dysfunction (ED). It comes in four doses, 2.5 mg, 5 mg, 10 mg, and 20 mg.The drug can be taken as needed in any of the four doses. The 2.5 mg and 5 mg doses are also approved for daily use for ED. Tadalafil in the 2.5 mg and 5 mg doses is also FDA-approved for men suffering from urinary symptoms due to benign prostatic hyperplasia (BPH) with or without ED.

Ro offers tadalafil starting at $8 per tablet. For full pricing details, please visit our pricing page.
