What Are the Side Effects of Testosterone Injections, Both Short-Term, and Long-Term?

Testosterone replacement therapy is a treatment option for men who have been diagnosed with hypogonadism, or low testosterone levels. Testosterone replacement therapy can take the form of injections, gels, patches, or pellets that are placed under the skin. Testosterone injections are the most common and effective form of testosterone replacement therapy. They are typically given on a weekly or bi-weekly basis.

While testosterone replacement therapy can be highly effective in treating low testosterone levels, it is not without its risks. The most common side effects of testosterone injections include:

  • Acne
  • Mood swings
  • Headaches
  • Increased appetite
  • Weight gain
  • Fluid retention
  • Gynecomastia (enlargement of breasts in men)
  • Oily skin
  • Allergic reaction

While the side effects of testosterone treatment injections are typically not serious and would sometimes only trigger an allergic reaction, they can be uncomfortable or inconvenient for some men. If you are experiencing any of the above side effects, talk to your doctor about ways to minimize them. For example, your doctor may recommend a different dosage or frequency of injections.

What Should You Do if You Experience Any Side Effects from Testosterone Injections?

If you experience any side effects from testosterone treatment injections, the first thing you should do is talk to your doctor. Your doctor will be able to determine if the side effects are due to the testosterone injections or something else. In most cases, the side effects of testosterone injections are not serious and can be easily managed.

However, in rare cases, testosterone injections can cause more serious side effects, such as heart attack, stroke, chest pain, or blood clots. If you experience any of these serious side effects, seek medical help immediately.

To sum up, there can be some serious side effects associated with testosterone treatment injections such as allergic reactions or sleep apnea. However, in most cases, these side effects are not serious and can be easily managed. If you experience any serious side effects from testosterone injections, seek medical help from a health professional immediately.
