The most common side effects of ED medicine are mild and temporary, and they may include headaches, facial flushing, nasal congestion, and indigestion.
However, these should subside once your body has adjusted to the medication. In rare cases, more serious side effects may occur, such as an erection that lasts for more than four hours or a sudden decrease in hearing or vision.
If you experience any of these symptoms, you should seek medical help immediately.
Generic ED pills can be taken with or without food, but it is important to note that fatty meals may decrease the effectiveness of the drug. In addition, you should not drink alcohol while taking ED pills as this may increase the risk of adverse side effects.
