Considerations for using MUSE1
Sexually transmitted diseases
MUSE offers no protection from the transmission of sexually transmitted diseases. Both you and your partner should be aware of this and take appropriate measures.
Specifically, MUSE will not protect you or your partner from sexually transmitted diseases like chlamydia, gonorrhea, herpes simplex virus (HSV), viral hepatitis, human immunodeficiency virus (HIV, the virus that causes AIDS), human papillomavirus (genital warts), or syphilis. Latex condoms should be used for protection against these sexually transmitted diseases.
Priapism
While it has not been reported in clinical trials, there is the possibility that an overdose of MUSE can cause priapism.
Priaprism is a painful erection of the penis that is sustained for hours and not relieved by sexual intercourse or masturbation. This condition is serious and, if untreated, it can lead to a permanent inability to have an erection. If you use MUSE and experience a prolonged erection, you should seek prompt medical attention.
Pregnancy
MUSE has no contraceptive properties.
Because MUSE has not been tested during human pregnancy, it is recommended that couples use adequate contraception if the female partner is of childbearing potential.
MUSE should not be used when having intercourse with a pregnant woman unless you also use latex condom barrier.
Other information for your partner
The most common reported side effects observed in women whose partners use MUSE are mild vaginal itching or burning.
Partners who have experienced an extended period of sexual abstinence are encouraged to talk to their healthcare professionals before resuming sexual intercourse. The use of a water-based lubricant may facilitate vaginal penetration.
