Tadalafil: Uses, Dosage, Side Effects & Buying Guide

When working with Tadalafil, an oral phosphodiesterase‑5 (PDE5) inhibitor that relaxes smooth muscle and increases blood flow to the penis. Also known as Cialis, it is prescribed to treat erectile dysfunction, the difficulty of achieving or maintaining an erection. As a member of the PDE5 inhibitor, a drug class that blocks the enzyme phosphodiesterase type 5 family, Tadalafil shares mechanisms with sildenafil and vardenafil. Understanding these links lets you compare options, dosage forms, and safety considerations before you decide where to buy.

Typical dosing ranges from 2.5 mg to 20 mg taken before sexual activity, with a long‑acting 36‑hour option that many call the “weekend pill.” The drug also comes in a daily low‑dose form (2.5 mg) for men who prefer continuous readiness. Tadalafil can be found as brand‑name Cialis or as a generic Cialis, a cost‑effective version of the same active ingredient. When you choose a product, compare the tablet size, inactive ingredients, and whether the label lists a certified manufacturer. These details affect absorption, side‑effect profile, and how the medication fits into your routine.

Safety, Side Effects, and Interactions

Common side effects include mild headache, flushing, upset stomach, and back pain; they usually disappear within a few hours. More serious concerns—such as sudden vision loss, hearing changes, or prolonged erections—require immediate medical attention. Tadalafil should not be combined with nitrates or certain alpha‑blockers because the combo can cause dangerous drops in blood pressure. If you have heart disease, uncontrolled high blood pressure, severe liver or kidney impairment, discuss alternatives with your doctor. Knowing these precautions helps you weigh benefits against risks and decide if Tadalafil fits your health profile.
