Description

Cialis 20 mg (Tadalafil)

Overview

Cialis 20 mg (Tadalafil) is a prescription medication used to treat erectile dysfunction (ED) and, in some cases, benign prostatic hyperplasia (BPH) — a condition characterized by an enlarged prostate.

Cialis belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors, which improve blood flow to specific areas of the body. Unlike other medications in its class, Cialis is known for its long duration of action, lasting up to 36 hours, earning it the nickname “the weekend pill.”

How It Works

Cialis works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), responsible for breaking down cyclic guanosine monophosphate (cGMP) — a chemical that relaxes smooth muscle in the penis.

During sexual stimulation, this relaxation allows increased blood flow to the penile tissues, helping achieve and maintain an erection.
In BPH, it helps relax smooth muscle in the bladder and prostate, improving urinary symptoms.

Usage Guidelines

• Take exactly as prescribed by your healthcare provider.

• For erectile dysfunction:

  • 20 mg dose is typically taken 30 to 60 minutes before sexual activity.

  • The effects may last up to 36 hours.

  • Do not take more than one dose per day.

• Cialis can also be prescribed for daily use at lower doses (2.5–5 mg) for men who prefer spontaneous sexual activity.

• Can be taken with or without food, but avoid heavy or high-fat meals before dosing, as they may delay onset.

• Swallow the tablet whole with water.

Safety Information & Precautions

• Do not use Cialis if you are taking nitrate medications (e.g., nitroglycerin, isosorbide) or recreational “poppers” containing amyl or butyl nitrite — this combination can cause a dangerous drop in blood pressure.

• Inform your doctor if you have heart disease, high or low blood pressure, kidney/liver problems, vision disorders, or a history of stroke.

• Avoid excessive alcohol intake, which can increase side effects such as dizziness or low blood pressure.

• Use cautiously if you are taking alpha-blockers or other antihypertensive medications.

• Not intended for use in women or individuals under 18 years of age.
