Testosterone undecanoate is a type of testosterone medication men take to increase their testosterone levels. It’s typically prescribed for men who have low testosterone due to certain medical conditions.
Though testosterone undecanoate can be very helpful, it’s important to understand the possible side effects. Knowing what to look for can help you make informed decisions about your health and seek medical attention if needed.
This article will discuss the various side effects linked to testosterone undecanoate, including common, serious, and rare side effects. We’ll also cover precautions you should take while taking this medication and what to watch for.
What is testosterone undecanoate?
Testosterone is the main sex hormone in men, and it’s responsible for the development of male characteristics. Testosterone undecanoate is a long-acting form of testosterone that’s injected into a muscle. From there, it slowly releases testosterone into the bloodstream, providing a steady dose.
Doctors prescribe this medication to men who have hypogonadism, a condition where the body doesn’t make enough testosterone on its own.
IMPORTANT WARNINGS AND PRECAUTIONS
Testosterone undecanoate injections, like any medication, require careful consideration and adherence to safety guidelines. It’s critical to understand the potential risks and contraindications before starting treatment.
General Warnings
Testosterone injections should only be administered in a healthcare setting by trained professionals due to the potential for serious side effects. Self-administration is not recommended.
It’s also important to note that testosterone undecanoate is not intended for treating age-related low testosterone. It’s typically prescribed for specific medical conditions where testosterone deficiency is confirmed.
Contraindications
Testosterone undecanoate is not suitable for everyone. You should not use this medication if:
- You are a woman who is pregnant, may become pregnant, or is breastfeeding.
- You have breast cancer or prostate cancer.
- You are allergic to testosterone or any of the ingredients in the injection.
Precautions
Before starting testosterone undecanoate, it’s essential to have an open and honest conversation with your doctor. Be sure to inform them about your complete medical history, including any existing medical conditions, allergies, and all medications you are currently taking. This information will help your doctor assess potential risks and monitor for any interactions.
Particular caution is advised for individuals with certain conditions, such as heart disease, kidney disease, liver disease, or sleep apnea. These conditions may be affected by testosterone therapy, and your doctor will need to carefully evaluate the potential risks and benefits before prescribing testosterone undecanoate.
Common side effects
Like all medications, testosterone undecanoate can cause side effects. It’s important to remember that not everyone experiences these, and the severity can vary.
Injection site reactions
Because testosterone undecanoate is usually administered via injection, you may notice some local reactions at the injection site. This can include pain, swelling, redness, or even a bit of itching. These reactions are usually mild and temporary, resolving on their own within a few days.
Skin-related side effects
Hormonal changes can sometimes wreak havoc on your skin. Some people taking testosterone undecanoate may experience acne, increased oiliness of the skin, or even hair loss. These issues are also seen in people taking finasteride, and if they become bothersome, talk to your doctor about potential remedies or adjustments to your treatment plan.
Mood changes
Hormones play a significant role in regulating mood, so it’s not surprising that testosterone therapy can sometimes lead to mood alterations. Some individuals may experience increased irritability, anxiety, or mood swings. If you notice significant changes in your mood, it’s crucial to discuss them with your healthcare provider.
Changes in libido
Testosterone is a key hormone in sexual function, so changes in libido are possible. Some people may experience an increase in sexual drive, while others may notice a decrease. It’s important to be aware of these potential changes and communicate any concerns to your doctor.
Other common side effects
In addition to the side effects mentioned above, some people may experience headaches, fatigue, or breast enlargement (gynecomastia). If you experience any unusual or bothersome side effects, it’s always best to consult with your healthcare provider.
SERIOUS SIDE EFFECTS
While testosterone undecanoate can be helpful for some, it’s important to be aware of the potential for serious side effects. Talk with your healthcare provider about whether the benefits outweigh the risks for you.
Cardiovascular Risks
Testosterone injections can cause your blood pressure to go up, so your doctor will want to keep an eye on that. Blood clots are another serious possibility that requires immediate medical attention. Let your doctor know about any history of blood clots.
Respiratory Issues
Serious lung problems, including pulmonary oil microembolism (POME), have been reported with testosterone undecanoate. POME is a condition where tiny droplets of oil enter the bloodstream and travel to the lungs, causing breathing problems.
Because of this risk, you’ll be closely monitored for the first 30 minutes after each injection. Symptoms of POME can include cough, shortness of breath, chest pain, dizziness, vision changes, anxiety, or even seizures. If you experience any of these symptoms after an injection, tell your doctor or nurse right away.
Allergic Reactions
Allergic reactions, including severe reactions, have been reported. Symptoms can include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or trouble breathing. Get emergency medical help right away if you think you’re having a serious allergic reaction.
Liver Problems
Liver damage is another serious potential side effect that needs immediate medical attention. Watch out for symptoms like yellowing of the skin or eyes (jaundice), dark urine, abdominal pain, and nausea. If you notice any of these, contact your doctor as soon as possible.
Prostate Issues
Testosterone can cause the prostate to enlarge and may promote the growth of existing prostate cancer. Because of this, regular prostate exams are a must to monitor for any abnormalities. Talk to your doctor about the risks and benefits of testosterone therapy if you have a history of prostate problems.
Sleep Apnea
Testosterone can make sleep apnea worse. If you have sleep apnea, talk to your doctor about whether testosterone therapy is right for you.
Psychological Effects
While less common, some people may experience increased aggression, depression, or other mood disturbances while taking testosterone. If you notice any significant changes in your mood or behavior, let your doctor know.
Drug Interactions
It’s critical to tell your doctor about everything you’re taking before starting testosterone undecanoate. This includes prescriptions, over-the-counter medications, and herbal supplements. You might not think that herbal remedy is important, but, as with estradiol interactions, it could be!
Testosterone can interact with certain medications. For example, it can boost the effects of blood thinners like warfarin, increasing your risk of bleeding. If you’re diabetic and taking insulin or oral medications to lower your blood sugar, testosterone could affect how well those work, and your doctor may need to adjust your dosage.
Monitoring and Management
If you’re taking testosterone undecanoate, it’s vital to work closely with your healthcare provider to manage potential side effects and make sure the medication is working as it should.
Regular Blood Tests
Your doctor will order regular blood tests to check your testosterone levels and adjust your dosage as needed. In addition to testosterone levels, your doctor will also monitor:
- Blood pressure
- Cholesterol and triglyceride levels
- Liver function
Monitoring for Side Effects
It’s also essential to keep an eye out for any unusual symptoms and report them to your doctor right away. Don’t try to tough it out or ignore changes in your body.
Following Doctor’s Instructions
Make sure to take your medication exactly as prescribed. Don’t skip doses or change the amount you’re taking without talking to your doctor first. Sticking to the prescribed dosage and injection schedule is critical for managing side effects and getting the most benefit from the medication.
Post-Injection Monitoring
For the first 30 minutes after each injection, you’ll need to be closely monitored to watch for POME (post-injection microembolism) or allergic reactions. This is why it’s usually done in a doctor’s office.
