Cialis 20 Milligrams: What You Need to Know

Cialis (tadalafil) is a medication often used to treat erectile dysfunction and benign prostatic hyperplasia.

1. How it works

- Tadalafil works by inhibiting the enzyme phosphodiesterase - 5 (PDE5). This enzyme breaks down cyclic guanosine monophosphate (cGMP), which is involved in the relaxation of smooth muscles in the blood vessels of the penis. By inhibiting PDE5, Cialis helps to increase blood flow to the penis, enabling an erection in response to sexual stimulation in men with erectile dysfunction.

2. Dosage and usage

- A 20 - milligram dose of Cialis is one of the common dosages. However, the appropriate dosage can vary depending on the individual's condition, response to the drug, and other factors.

- It is typically taken as needed for erectile dysfunction, and should not be taken more than once per day.

- It should be used under the supervision of a healthcare provider, as there can be potential side effects and interactions with other medications.

3. Side effects

- Common side effects may include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose.

- In some cases, more serious side effects can occur, such as sudden vision loss or hearing problems, although these are relatively rare.

4. Precautions

- Cialis should not be used by individuals who are taking nitrates (e.g., nitroglycerin) for chest pain, as this can cause a dangerous drop in blood pressure.

- It is important to inform your doctor about all medications, supplements, and medical conditions you have before starting Cialis.
