A common side effect of Fildena 150mg is headaches. This is because PDE5 drugs like Viagra and Cialis can dilate the blood vessels in the brain, which can trigger migraines or headaches.
This can be a very painful experience for many people, especially those who are already prone to headaches. It can also cause dizziness, lightheadedness, and other symptoms of low blood pressure.
In some cases, this can lead to fainting or a loss of consciousness. It is important to contact your doctor immediately if these symptoms occur.
