Muse is a medicine that helps you get and keep an erection by increasing blood flow to the penis.
The usual starting dose is 500 micrograms. Do not increase the dose yourself; talk to your doctor if it's not enough.
Muse is used with a single-use applicator, which puts the medicine into your urethra (the tube urine comes out of). Your doctor will show you how to use it.
Do not use more than two doses per 24 hours or more than seven doses per week.
