Both Viagra (sildenafil) and Cialis (tadalafil) treat erectile dysfunction, but their side effects differ in frequency and type. Understanding these differences helps you make an informed decision with your doctor.
Common side effects for both include headache, flushing, nasal congestion, and indigestion. However, Cialis users report these less frequently.
Viagra’s side effects might include visual disturbances (blurred vision, changes in color perception), and a higher chance of experiencing back pain or muscle aches.
Cialis, conversely, may cause back pain and muscle aches more often than Viagra, but typically less severely. It also carries a slightly increased risk of prolonged erection (priapism), requiring immediate medical attention.

Remember, this is not exhaustive. Always consult your doctor to discuss potential side effects and determine the best treatment for your individual needs.
