Tadalafil is a PDE-5 (phosphodiesterase) inhibitor that is intended for impotence treatment. It is a prescription-only medication that can enhance blood flow to the penis. Cialis is the brand name under which tadalafil launched in 2003. It works by inhibiting the action of phosphodiesterase type-5 (PDE-5) enzyme. Though Cialis is safe and effective in treating erectile dysfunction in most men, it can cause mild to moderate side effects, especially if not used as directed.

Cialis side effects

As with any medication, there are some possible side effects associated with Cialis. These side effects are not experienced by everyone. In fact, Cialis is well tolerated in most people. In the majority of cases, users may develop minor side effects that require no, or minimal, further treatment. In a clinical trial, tadalafil was studied extensively and evaluated in over 5,700 people. Based on the study, the most common side effects experienced by more than 2% of people were headaches, facial flushing, vision changes, indigestion, dizziness, and abdominal pain. A number of other rare side effects of Cialis experienced by less than 2% of people were chest pain, loss of hearing, dry mouth, insomnia, vertigo, and hypertension.

Precautions for Cialis

Cialis should always be taken under the guidance of a doctor. Among the people who should consult a doctor before taking tadalafil are those who are allergic to its ingredient tadalafil. In particular, people taking nitrate drugs, blood pressure medications, erythromycin, alpha blockers, and anti-fungal medications should not take Cialis without their doctor’s authorization. You need to take certain precautions prior to taking this medication if you have health conditions such as high blood pressure, low blood pressure, multiple myeloma, kidney disease, heart disease, and stomach ulcers.
