Jatenzo Capsule: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

Jatenzo Capsule is a liquid-filled oral capsule containing testosterone undecanoate, part of the androgens and anabolic steroids drug class. It is used as testosterone replacement therapy in adult men whose bodies do not produce enough natural testosterone due to certain medical conditions (hypogonadism). It is not for low testosterone caused by normal aging and is not approved for women or children under 18. It works by replacing testosterone the body is not making enough of on its own.

What is Jatenzo Capsule

Jatenzo is a liquid-filled capsule that contains testosterone. It is used to treat low testosterone levels in adult men caused by certain medical conditions that stop the body from making enough natural testosterone (hypogonadism).

Jatenzo Capsule uses

• Testosterone replacement therapy in adult men whose bodies do not produce enough natural testosterone (hypogonadism) due to conditions affecting the testicles, pituitary gland, or hypothalamus
• Not for treating low testosterone caused by normal aging (age-related hypogonadism)
• Not approved for use in women or in children under 18 years old

Benefits of Jatenzo Capsule

Jatenzo replaces testosterone that the body is not producing enough of on its own, helping restore testosterone levels to a normal range.

How Jatenzo Capsule works

Jatenzo works by replacing testosterone that the body normally produces, which is needed for growth, development, and normal male sexual function and characteristics.

Jatenzo Capsule dosage

Take Jatenzo exactly as your doctor prescribes and follow the directions on your prescription label. Take by mouth two times a day, once in the morning and once in the evening, with food. Your doctor may need to adjust your dose over time based on blood test results, so do not change your dose on your own. If you miss a dose, take it as soon as you remember, but skip it if it is almost time for your next dose — do not take two doses at once. Do not keep leftover medicine; ask your pharmacist about a take-back program instead of throwing it away.

Warnings and precautions

• Jatenzo must not be used by women who are pregnant because it can harm the unborn baby. It is not approved for use in women at all, so it is not intended to be used by women who are breastfeeding either.
• Tell your doctor if you have kidney problems before starting Jatenzo, since it can cause fluid retention and swelling that may be more serious in people with existing kidney disease.
• Tell your doctor if you have liver problems before starting Jatenzo. Report any signs of liver trouble such as yellowing skin or eyes, dark urine, or stomach pain right away.
• Drinking alcohol is likely safe while taking Jatenzo, but alcohol can lower testosterone levels. Ask your doctor how much alcohol, if any, is safe for you.
• Jatenzo can raise blood pressure, which increases the risk of heart attack, stroke, or death over time. Your doctor will monitor your blood pressure and may need to start or adjust blood pressure medicine.
• Do not take Jatenzo if you have breast cancer, known or suspected prostate cancer, or if you are a pregnant woman.
• Jatenzo can increase red blood cell counts, which raises the risk of blood clots, stroke, and heart attack. Your doctor will check your blood counts regularly.
• Jatenzo can cause blood clots in the legs or lungs. Seek urgent medical care for leg pain, swelling, or redness, or for sudden shortness of breath or chest pain.
• Jatenzo may worsen an enlarged prostate and may increase the risk of prostate cancer. Your doctor will check your prostate before and during treatment.
• Jatenzo is a controlled substance because testosterone can be misused or abused. Keep it in a safe place and never share it with anyone else.
• Jatenzo may cause new or worsening depression or suicidal thoughts. Tell your doctor right away about any mood changes.
• Just one accidental or improper dose can be dangerous, so leftover medicine should not be kept.

Storage

• Store at room temperature between 68°F to 77°F (20°C to 25°C)
