Risks and warnings for Xyosted (testosterone enanthate)
Xyosted (testosterone enanthate) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Higher red blood cell count
Xyosted (testosterone enanthate) can raise your red blood cell count, which can lead to blood clots. Your prescriber will check your red blood cell levels before you start treatment and during it. If your levels get too high, you might have to stop the medication until they go back to normal.
Blood clots
Xyosted (testosterone enanthate) itself can cause life-threatening blood clots in your legs or lungs. If you notice leg pain, swelling, warmth, or redness, tell your prescriber right away, as these could be signs of a blood clot in your leg. If you suddenly have trouble breathing or chest pain, it could mean a clot has moved to your lungs. If this happens, you might have to stop taking the medication.
Worsening of enlarged prostate and risk of prostate cancer
- Risk factors: History of enlarged prostate
Taking Xyosted (testosterone enanthate) can worsen certain symptoms if you have an enlarged prostate, also called benign prostatic hyperplasia (BPH). Let your prescriber know if you notice changes in urination, such as going more often at night, feeling like you need to go right away, having trouble starting, leaking, or a weak stream.
Xyosted (testosterone enanthate) might also raise your risk of prostate cancer. Your prescriber might order blood tests or check your prostate before and during treatment to help keep you safe.
Higher blood pressure
- Risk factors: History of high blood pressure
Xyosted (testosterone enanthate) can raise your blood pressure. Having high blood pressure over time can raise your risk for heart problems, like heart attack or stroke.
Get emergency help right away if you have chest pain, cold sweats, left arm pain, trouble breathing, trouble walking, trouble speaking, or weakness on one side of the body. You should check your blood pressure often while you’re using this medication, especially if you already have high blood pressure.
Potential for misuse, addiction, and dependency
- Risk factors: Taking more Xyosted (testosterone enanthate) than prescribed | Taking Xyosted (testosterone enanthate) with other testosterones
Xyosted (testosterone enanthate) is a controlled substance because it can be misused or cause dependence, especially if you take higher doses than prescribed or combine it with other testosterone products.
Misusing Xyosted (testosterone enanthate) can lead to addiction. This medication is only approved by the FDA to treat low testosterone in men. Taking Xyosted (testosterone enanthate) for other reasons can cause serious heart and mental health problems. Always use it exactly as prescribed.
Lower sperm count
- Risk factors: Taking more Xyosted (testosterone enanthate) than prescribed
Xyosted (testosterone enanthate) can lower sperm count, which might make it harder to have a baby. This is more likely with higher doses, and the effect could be permanent. Tell your prescriber if you plan to have children before starting this medication.
Liver problems
Using certain forms of testosterone, such as methyltestosterone or testosterone enanthate intramuscular injection, for a long time can cause serious liver problems. This isn't a known risk of Xyosted (testosterone enanthate), but it's still important to look out for symptoms of liver damage. Let your prescriber know if you have stomach pain, pale stools, dark urine, or yellowing of your skin or eyes.
Swelling in the arms and legs (edema)
- Risk factors: History of heart, liver, or kidney conditions | Taking other medications that cause swelling like corticosteroids
Xyosted (testosterone enanthate) can make your body keep extra salt and water, which might lead to edema, or swelling in your arms and legs. This is more likely if you take other medications that cause swelling, like corticosteroids (e.g., prednisone, methylprednisolone). Swelling can be more serious if you have heart, liver, or kidney problems. Tell your prescriber if you notice these symptoms.
Breathing problems during sleep (sleep apnea)
- Risk factors: Obesity | History of lung problems
Xyosted (testosterone enanthate) can make sleep apnea, a condition that causes breathing problems during sleep, worse in some people. This is more likely if you have obesity or lung problems. Talk to your prescriber if you or your partner notice loud snoring, pauses in breathing during sleep, or if you feel very tired during the day.
Enlarged breasts
Some people using Xyosted (testosterone enanthate) might develop gynecomastia, which is swelling or enlargement of breast tissue in men. You might also feel soreness or pain in your chest area. Talk to your prescriber if you have questions about this side effect.
Changes in cholesterol levels
Testosterone treatments like Xyosted (testosterone enanthate) can affect your cholesterol levels. Your prescriber might need to adjust your dose or stop the medication if these changes happen. They will check your cholesterol regularly, especially when you first start using the medication.
High calcium levels
- Risk factors: History of cancer
Xyosted (testosterone enanthate) can raise calcium levels in your blood and urine, especially in people with cancer. High calcium levels can cause symptoms such as muscle weakness, frequent urination, thirst, stomach pain, and blood in the urine. Your prescriber might check your blood regularly during treatment to make sure your calcium levels stay normal.
Mood changes and thoughts suicide
- Risk factors: History of depression | History of mental health conditions
Xyosted (testosterone enanthate) can affect your mood. Some people have reported depression, anxiety, or thoughts of self-harm while taking this medication.
Tell your care team right away if you notice new or worsening depression, anxiety, mood changes, or thoughts of hurting yourself. Family members and caregivers should also watch for these changes and seek medical help if they occur.

The following Xyosted (testosterone enanthate) side effects have also been reported
Discuss these possible effects with your doctor:
Tumors of the liver, liver cancer, or peliosis hepatis (a form of liver disease) have occurred during long-term, high-dose therapy with androgens. Although these effects are rare, they can be very serious and may cause death.
Androgens can stimulate existing prostate cancer in men who already have it but have not yet been diagnosed. Also, the prostate (a male gland) may become enlarged. Enlargement of the prostate does not mean that cancer will develop. If enlargement occurs and you have difficulty in urinating, it is a good idea to be checked by your doctor.
When androgens are used in women, especially in high doses, male-like changes may occur, such as hoarseness or deepening of the voice, unnatural hair growth, or unusual hair loss. Most of these changes will go away if the medicine is stopped as soon as the changes are noticed. However, some changes, such as voice changes or enlarged clitoris, may not go away.
When androgens are used in high doses in males, they interfere with the production of sperm. This effect is usually temporary and only happens during the time you are taking the medicine. However, discuss this possible effect with your doctor if you are planning on having children.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
