What is MUSE (medicated urethral suppository for erection)?

MUSE is short for "medicated urethral system for erection." This treatment is based on the discovery that the urethra (the tube passing from the bladder to the tip of the penis through which urine is passed and semen ejaculated) can absorb certain medications, which can then pass into the surrounding erectile tissue creating an erection.

The active ingredient in MUSE is alprostadil. This is identical to a naturally occurring substance within the penis which is involved in the development of an erection. Alprostadil has been used in the treatment of impotence for many years. Before the introduction of MUSE it had to be injected into the penis when an erection was wanted. Alprostadil relaxes the muscles in the erectile tissue of the penis allowing increased blood flow, the basis of a normal erection. In MUSE, alprostadil is formulated as a small pellet which is supplied in a specially designed applicator. Each MUSE applicator is individually foil wrapped. The applicator has a narrow stem which can be introduced easily into the urethra. After inserting the applicator, the alprostadil pellet is then released into the urethra by depressing a button on the top of the applicator. The manufacturer recommends that immediately prior to insertion of MUSE, the man urinates and then gently shakes the penis several times to remove excess urine. A moist urethra makes administration of MUSE easier and facilitates the absorption of alprostadil.

Physicians will commonly have a patient try a suppository in the office to determine appropriate dosage. Before using urethral suppositories, the man urinates. This helps to insure the moist surfaces that help the medication to be absorbed. With a small applicator, the man inserts a pellet of medication into his urethra, the small hole on the tip of the penis. He then massages his penis for about a minute to help the pellet dissolve. To help speed absorption, he should also remain upright for several minutes. He may also place a small rubber band around the base of his penis before inserting the suppository. This can help hold the medication in his penis.

A man generally will get an erection within 10-15 minutes of application. The erection will last about 30-60 minutes. When this form of treatment is effective, an erection generally lasts 30 to 60 minutes. Extremely rarely a prolonged erection may occur. MUSE can be used twice in any 24 hour period, however 2 units should not be used consecutively.

Different doses: MUSE is available in four strengths - 125 mcg, 250 mcg, 500 mcg and 1,000 mcg. The initial dose is selected by the doctor.

Side effects have been reported only infrequently. When first using MUSE, some men experience minor discomfort from insertion but prior urination will reduce the chance of this happening. Following the first dose of MUSE, fainting has occurred, but only in an extremely small proportion of men. However, for this reason, it is recommended that the first dose of MUSE should be in the doctor's office. Other side effects that have been reported, albeit extremely rarely, include light-headedness, dizziness, fainting, rapid pulse and swelling of the leg veins. Patients are advised not to drive up to one hour after using MUSE.
