Precautions

It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and check for any problems or unwanted effects that may be caused by this medicine.

This medicine should not be used by women. Testosterone may cause birth defects if a pregnant woman comes in contact with the patch or medicine. Make sure your doctor knows if your sexual partner is pregnant. If a pregnancy occurs while you are using this medicine, tell your doctor right away.

If a woman comes in contact with the patch, wash the skin area right away with soap and water to remove all the medicine. If the patch sticks to a woman, remove the patch right away and wash her skin thoroughly with soap and water.

If your female partner starts to have male-like changes such as unusual hair growth or increased acne, check with your doctor.

Tell your doctor if you experience too frequent erection of the penis, nausea, vomiting, yellowing of your skin or the whites of your eyes, or swelling of the ankle.

This medicine contains aluminum that may cause skin burns at the patch site if you have a procedure called a magnetic resonance imaging (MRI) scan while you are wearing the patch. You must remove the patch before your MRI to prevent skin burns.

Check with your doctor immediately if mild, burn-like skin blisters, redness, itching, or swelling occurs at the site of application during or after treatment.
