Missed Dose
If the patch falls off, or if you miss a dose, apply a new patch right away. If it is after noon the next day and you remember that you missed a dose, or if your patch fell off, do not apply a new patch, but instead resume your usual dosing schedule. Do not double the dose to catch up.
How To Use
Read the Patient Information Leaflet provided by your pharmacist before you start using testosterone and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist. Apply to a dry, clean area of skin on the back, abdomen, upper arms, or thighs. Do not apply the patch to skin that has been treated with a topical ointment because doing so may decrease the amount of testosterone that your body will absorb. The patch site must not be oily or irritated. Do not place on the scrotum or on bony areas such as the shoulders or hips. To use the patch, remove the protective backing to expose the sticky surface. Immediately place the patch with the sticky side down on clean, dry skin, usually once nightly or as directed by your doctor. Wear the patch for 24 hours, then replace it with a new patch. Be sure to apply the patches to a different area each day. Wait 7 days before applying a patch to the same area of skin. The patch may be worn during sex. It is okay to wear the patch while showering or swimming. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each night. If the patch comes loose, press around the edges of the patch to secure it in place. If the patch falls off, see Missed Dose section. To discard a patch, fold it so the adhesive side is on the inside. Place the folded patch in the pouch from which the new patch is taken and discard it in the trash. Inform your doctor if your condition persists or worsens.

Other side effects may include acne, headache, hair loss, anxiety, or a change in sexual desire. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.

In the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur. Rarely, burn-like reactions under the patch may occur. This is most likely to happen if the patch is placed on bony areas of the body (see How to Use section for proper application sites). Permanent scarring may occur, so tell your doctor immediately if this type of reaction occurs while you are using this patch. If you have diabetes, especially if you are using insulin, testosterone may decrease your blood sugar. Be prepared to treat low blood sugar while you are using this medication.
