| Side Effect | Description |
| Hot flashes | Triptorelin can cause hot flashes or flushing, which are common side effects characterized by sudden feelings of warmth, sweating, and redness of the face and body. |
| Decreased libido | A decrease in libido (sex drive) can occur as a side effect of triptorelin treatment due to the suppression of testosterone levels. |
| Erectile dysfunction | Triptorelin may cause erectile dysfunction or difficulty achieving/maintaining erections in individuals assigned male at birth. |
| Gynecomastia | In individuals assigned male at birth, triptorelin can cause breast development (gynecomastia) due to the suppression of testosterone and promotion of estrogenic effects. |
| Mood changes | Some individuals may experience mood swings, depression, or changes in emotional well-being while taking triptorelin. |
| Fatigue | Fatigue or feelings of lethargy may occur as a side effect of triptorelin treatment. |
| Headaches | Headaches are a common side effect of triptorelin use, though they are usually mild and temporary. |
| Injection site reactions | Pain, redness, or swelling at the injection site are possible side effects of triptorelin injections. |
| Osteoporosis | Long-term use of triptorelin can potentially increase the risk of osteoporosis due to decreased bone density. Bone density monitoring and supplementation with calcium and vitamin D may be recommended. |
| Muscle weakness | Weakness or decreased muscle strength can occur as a side effect of triptorelin treatment. |
| Thromboembolic events | While less common, there is a risk of thromboembolic events (such as blood clots) associated with triptorelin use, particularly in individuals with other risk factors for thrombosis. |
| Decreased fertility | Triptorelin suppresses gonadal function, leading to decreased fertility in individuals assigned male at birth. It's essential to discuss fertility preservation options with a healthcare provider if fertility preservation is desired. |
| Rare allergic reactions | Although rare, some individuals may experience allergic reactions to triptorelin, including rash, itching, swelling, or difficulty breathing. Immediate medical attention is necessary if any signs of an allergic reaction occur. |
