Cialis, also known as tadalafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. It’s a phosphodiesterase-5 (PDE5) inhibitor, meaning it relaxes blood vessels, allowing for easier erections. Unlike some other ED medications, Cialis offers a longer duration of action, up to 36 hours for some formulations. This means you might experience its effects for a longer period after taking a single dose.
Dosage and Administration
Cialis comes in various dosages, typically ranging from 2.5mg to 20mg. Your doctor will determine the appropriate dosage based on your individual needs and health status. It’s crucial to follow your doctor’s instructions precisely. The medication is usually taken orally, with or without food, approximately 30 minutes before anticipated sexual activity. However, for daily use formulations, the timing is less critical.
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and indigestion. More serious, though rare, side effects can include sudden vision loss or hearing loss. Seek immediate medical attention if you experience any of these. Always discuss potential side effects with your healthcare provider before starting treatment.
Interactions and Precautions
Cialis can interact with certain medications, particularly nitrates used to treat angina. Combining them can cause a dangerous drop in blood pressure. If you take nitrates or other medications, inform your doctor before using Cialis. Individuals with heart conditions, liver disease, or kidney disease should also discuss their suitability for Cialis with their doctor.
