It is illegal to purchase testosterone gel without a prescription. The American government has classified it as a controlled substance, according to Drugs.com. Because of the serious health risks associated with this medication, patients should only use testosterone gel under the close supervision of a medical doctor, according to RXList.com.
Recommended starting doses and application sites on the body vary by brand, so you should read the instructions and follow them carefully, notes RxList. Application includes spreading the gel on specific parts of the skin, such as the upper arms, shoulders or stomach, then leaving the gel to dry before you put your clothes back on.
Serious side effects associated with testosterone gel include difficulty with urination, increased risk of prostate cancer, blood clots, lowered sperm counts, sleep apnea, and increased risk of heart attack or stroke. Less serious risks include acne and skin irritation. You should also avoid letting women or children come into contact with areas of your skin that have been exposed to the gel. The gel does transfer and can cause serious health issues in others such as an enlarged penis or clitoris, aggressive behavior, or early puberty, according to RxList.
To avoid accidentally transferring the gel to others, make sure you immediately wash your hands with soap and water after use. Cover the application area with clothing after it dries. If a woman or child accidentally comes into contact with the applied area, they should immediately wash the contact site with water and soap, states RxList. Tell your doctor about other medicines you're taking and if you experience any side effects.
