Vardenafil and sildenafil are medications used to treat erectile dysfunction (ED) by increasing blood flow to the penis during sexual stimulation. They belong to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. While generally safe and effective for most men, these medications can potentially cause side effects.
Common side effects of vardenafil and sildenafil include headache, facial flushing, nasal congestion, indigestion, and dizziness. These side effects are usually mild and transient, resolving on their own as the medication is metabolized and eliminated from the body.
Less common but more serious side effects can include vision changes, such as increased sensitivity to light or blurred vision. In rare cases, vardenafil and sildenafil have been associated with more severe visual disturbances, including temporary loss of vision or sudden decrease or loss of hearing. If you experience any sudden changes in vision or hearing while taking these medications, it is important to seek immediate medical attention.
Other potential side effects can include priapism, a prolonged and painful erection lasting more than four hours, which requires urgent medical attention to prevent tissue damage to the penis. Additionally, allergic reactions to vardenafil or sildenafil are rare but possible and may present as rash, itching, swelling (especially of the face/tongue/throat), severe dizziness, or difficulty breathing.
It's essential to use vardenafil or sildenafil as prescribed by a healthcare provider and to inform them of any other medications or health conditions you have, as they can interact with certain drugs or exacerbate certain medical conditions. If you experience any bothersome or persistent side effects while taking vardenafil or sildenafil, it is important to discuss them with your healthcare provider. They can provide guidance, adjust the dosage if necessary, or explore alternative treatment options to ensure your safety and well-being.
