If you have a serious heart, liver, or kidney disease, Testex treatment may cause severe complications in the form of fluid retention, which may be accompanied by congestive heart failure at times.

Before starting treatment and during treatment, your doctor will check the following parameters in your blood test: testosterone level and complete blood count.

• if you have an enlarged prostate (benign prostatic hyperplasia)
• if you have or suspect you may have breast cancer (a rare disease in men)

• you have blood clotting problems known as "thrombophilia" (a blood clotting problem - this increases the risk of developing blood clots in the blood vessels ("thrombosis"))
• factors that increase the risk of blood clots in a vein: previous blood clots in a vein; smoking; obesity; cancer; immobility; if a close family member has had a blood clot in the leg, lung, or other organ at a young age (for example, under 50 years); or as you age.

How to recognize a blood clot: painful swelling of a leg or sudden change in skin color, for example, paleness, redness, or blue, sudden difficulty breathing, sudden and inexplicable cough that may cause bleeding; or sudden and intense chest pain, intense dizziness, or intense stomach pain, sudden loss of vision. Seek urgent medical attention if you experience one of these symptoms

• if you experience difficulty urinating due to prostate gland enlargement. Your doctor will perform checks to evaluate the size of the prostate.
• if you have severe heart, kidney, or liver disease; you may develop complications, such as edema (swelling due to water or fluid retention) with or without heart failure. In this case, you must stop treatment immediately.
• if you have high blood pressure (hypertension), as Testex may increase it.
• if you have elevated calcium levels in the blood or urine due to bone cancer, your doctor may advise you to undergo regular blood tests.
• if you have high blood pressure.
• if you suffer from epilepsy.
• if you suffer from migraines.

These diseases may worsen when using Testex. If you experience any of the mentioned diseases, consult your doctor again and ask what to do.

Your doctor must perform the following blood tests before and during treatment: complete blood count, lipid profile (blood fat level), liver function analysis, and blood testosterone levels.
