- are currently using alpha-blockers
Common, and usually mild, side effects of PDE5 inhibitors can include:
- headaches
- flushing
- symptoms resembling those of the common cold
- stomach upset
- muscle and back pain
Rare side effects may include:
- changes in vision, or sudden loss of vision, for which people with heart disease or diabetes are more at risk
- sudden loss of hearing
- prolonged or painful erections that will require treatment to prevent lasting damage
