Cialis (Tadalafil) 20mg is a medication used to treat erectile dysfunction (ED) in adult men. It works by increasing blood flow to the penis, which helps a man to achieve and maintain an erection.

The usual starting dose of Cialis is 10mg, taken at least 30 minutes before sexual activity. The dose can be increased to 20mg or decreased to 5mg, depending on how well it works and how well it is tolerated. Cialis can be taken with or without food, but it should not be taken more than once a day.

Like all medications, Cialis can cause side effects, although not everyone experiences them. Some common side effects of Cialis include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. If you experience any severe or persistent side effects, you should seek medical attention.

It’s important to note that Cialis should not be taken by women or children. It should also not be taken by men who are taking nitrates, which are commonly used to treat chest pain (angina), or by men who have had a recent heart attack or stroke. Always consult with a healthcare provider before taking Cialis or any medication.
