MUSE, Caverject and Vitaros are all alprostadil-based erectile dysfunction medications. They each have a variety of dosages and come in different forms. While MUSE is a urethral suppository, Vitaros is a cream that is inserted into the urethra using an Accudose container. So it’s applied in a very similar way, but the drug is in a different form.
Caverject, on the other hand, comes in the form of an injection delivered into the base of the penis. So this is the same medicine, but is delivered into the body in a different way.
