What is the best effective treatment for impotence?
Are there any potential side effects of taking medication to treat impotence?
Yes, like all medications, erectile dysfunction drugs can cause side effects. Common side effects can include headaches, flushing, and upset stomach. More serious but rare side effects can include sudden vision or hearing loss, or an erection that lasts longer than four hours (which requires immediate medical attention). It's always important to speak with a healthcare provider about the potential risks and benefits of any medication.
