Testosterone replacement therapy (TRT) can cause side effects, so it’s important to understand what to expect before starting treatment. Side effects can vary depending on the type of medication and how your body responds.
Side effects vary by medication and individual response. They may include:
Acne or oily skin
Fluid retention
An increased red blood cell count
Breast tenderness or enlargement
Irritability, mood changes or sleep disturbances
Changes in libido
Reduced sperm production or testicular shrinkage
Skin irritation where Testogel is applied
Testosterone treatment may increase the risk of blood clots, and prostate health must be monitored. Seek urgent medical help if you develop sudden leg pain or swelling, unexplained shortness of breath, chest pain or a rapid heartbeat.
Rarely, medication can cause a serious allergic reaction. Get immediate help for symptoms such as swelling of the face, tongue or throat, severe dizziness, breathing difficulty or a widespread itchy rash.
Read the patient information leaflet supplied with your medication for the full list of side effects, contraindications and precautions.
Your doctor will review your individual health, test results and goals before recommending treatment. Do not start, stop or change testosterone treatment without medical advice.
