This medication is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions, including growth and development of the genitals, muscles, and bones. It also helps cause normal sexual development (puberty) in boys. Testosterone belongs to a class of drugs known as androgens. It works by affecting many body systems so that the body can develop and function normally.
Testosterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty.
This medication should not be used in women.
How To Use
Take this medication by mouth, usually twice daily with breakfast and with an evening meal, or as prescribed by your doctor. Swallow the capsules whole. Do not chew or open the capsules. Doing so can change how well the medication works.
Dosage is based on your medical condition, testosterone blood levels, and response to treatment.
Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day.
Do not suddenly stop using testosterone if you have been using it regularly for an extended time or if it has been used in high doses. In such cases, your body will no longer make its own testosterone, and withdrawal reactions (such as tiredness, weakness, depression) may occur. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.
Abnormal drug-seeking behavior is possible with this medication, and it is frequently misused for its muscle-enhancing effects. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Doing so may increase serious side effects (such as increased risk for heart disease, stroke, liver disease, ruptured tendons/ligaments, improper bone development in adolescents). Properly stop the medication when so directed.
Nausea, vomiting, headache, skin color changes, increased/decreased sexual interest, oily skin, hair loss, and acne may occur. If any of these effects persist or worsen, tell 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. Many people using this medication do not have serious side effects when it is used at normal doses.
