C20 Cialis, like other medications, can cause side effects. The most common include headache, facial flushing, nasal congestion, and indigestion. These typically are mild and temporary.
Some users report muscle aches or back pain. These are usually not severe and resolve on their own. Less frequent side effects include changes in vision (blurred vision, sensitivity to light), dizziness, and hearing loss.
Important Note: If you experience a sudden decrease or loss of vision, or a sudden decrease or loss of hearing, seek immediate medical attention. These could be signs of a serious problem.
Severe allergic reactions are rare but possible. Symptoms include hives, swelling of the face, lips, tongue, or throat, and difficulty breathing. If you experience any of these, contact emergency services immediately.
