Mixing viagra and cialis:

Mixing viagra and cialis is not recommended, as they are both medications used to treat erectile dysfunction (ED) and work in similar ways, increasing blood flow to the penis. Combining these medications can significantly increase the risk of side effects and may be harmful. Both Viagra and Cialis belong to the same class of medications called PDE5 inhibitors. If you feel that your current treatment is not effective, consult your healthcare provider to discuss alternative treatment options or adjust your prescription.
