An oral medication called a phosphodiesterase-5 (PDE5) inhibitor, Cialis (tadalafil), is used to treat impotence (also known as erectile dysfunction, or ED).

Headache, muscle pain, flushed skin, and nausea are typical adverse reactions.

Health Benefits

When compared to a placebo, Cialis has been shown to improve erectile function. In one study, men with ED who took Cialis were more likely than those who took a placebo to have a positive response to sexual activity.

The treatment of benign prostatic hyperplasia (BPH)-related urinary symptoms with cialis may also be successful. In comparison to men with BPH who took a placebo, those who took Cialis saw improved urinary symptoms and less urinary obstruction.

Possible Side Effects

Cialis frequently causes headaches, muscle pain, skin flushing, and nausea. Low blood pressure, an irregular heartbeat, and priapism (a painful erection lasting longer than four hours) are more severe side effects.

Dosages

In tablet form, Cialis comes in doses of 2.5, 5, 10, and 20 mg. Most men should start with a dose of 10 mg, which can be changed based on response.

Drug Interactions

Alpha blockers, nitrates, and antidepressants, among others, may interact with cialis. Low blood pressure, an irregular heartbeat, and priapism may result from these interactions.

Alcohol

While taking Cialis, drinking alcohol increases the risk of low blood pressure, lightheadedness, and headache. If you're taking this medication, it's advised that you abstain from alcohol.

Pregnancy and Breastfeeding

It is not advised to take Cialis while nursing or pregnant. This medication may have negative effects on a nursing infant and pass into breast milk.

Mechanism of Action

A phosphodiesterase 5 (PDE5) inhibitor called Cialis (tadalafil) is prescribed to treat erectile dysfunction (ED). The recommended Cialis dosage for once daily use is 5 mg, taken at about the same time each day, regardless of when sexual activity takes place.
