Trelstar ^*

Trelstar is administered as an intramuscular injection by a healthcare professional. It is typically injected into the buttock muscle. The medication is a long-acting depot formulation, meaning it releases the drug slowly over a set period. This allows for dosing every four, twelve, or twenty-four weeks, depending on the specific product and your doctor's prescription. You must receive these injections at your doctor's office or a clinic.

Trelstar is not a cure for prostate cancer but is used as a palliative treatment. This means its primary goal is to relieve symptoms and slow the progression of advanced, hormone-dependent prostate cancer. It works by reducing testosterone levels, which can help shrink tumors and alleviate issues like bone pain. It is an important part of managing the disease and improving a patient's quality of life.

The most common side effects of Trelstar are due to its testosterone-lowering effects. These frequently include hot flashes, similar to menopause in women. Other common effects are pain or swelling at the injection site, headache, decreased libido, fatigue, and general body aches. Most of these side effects are manageable. You should always discuss any persistent or bothersome side effects with your doctor for proper guidance.

Trelstar begins to work right after the first injection, but its effects change over time. Initially, it causes a temporary surge in testosterone, which might briefly worsen symptoms for about a week. This is known as a 'tumor flare.' After this initial phase, testosterone levels fall significantly within two to four weeks. At that point, you should begin to notice an improvement in your cancer symptoms as the treatment takes full effect.

A 'tumor flare' with Trelstar is a temporary worsening of prostate cancer symptoms that can occur during the first week or two of treatment. This happens because Trelstar initially causes a surge in testosterone before lowering it. This surge can increase bone pain, urinary difficulties, or other cancer-related symptoms. Your doctor may prescribe another medication for a short time to help manage these initial flare-up symptoms effectively.

Trelstar can reduce bone mineral density, especially with long-term use. The medication works by significantly lowering hormone levels like testosterone in the body. These hormones help maintain strong bones. A reduction in these hormones over several months or years can lead to thinning of the bones (osteoporosis), increasing the risk of fractures. Your doctor may monitor your bone density during your treatment and suggest supplements or other medications.

Trelstar must be given on a strict, regular schedule to be effective. Missing or delaying a dose can cause your hormone levels to rise again, which may allow the cancer to grow or puberty to resume. It is very important to keep all your scheduled appointments for injections. If you accidentally miss an appointment, you should contact your doctor's office immediately to reschedule and get back on track as soon as possible.

Trelstar is a type of hormone therapy, not a traditional chemotherapy. Chemotherapy works by directly killing fast-growing cells throughout the body, including cancer cells. In contrast, Trelstar works by changing the body's hormonal signals to stop feeding hormone-sensitive cancer cells. This targeted approach means it often has different side effects than those typically associated with chemotherapy, such as hair loss or severe nausea.

When Trelstar treatment for central precocious puberty is stopped, its effects are reversible. The medication's suppression of the pituitary gland ends, and the body resumes producing puberty-related hormones. Puberty will then restart, allowing sexual development to proceed. The timing for stopping Trelstar is a decision made with a pediatric endocrinologist once the child has reached a more appropriate age for puberty to occur naturally.

Trelstar may cause weight gain as a possible side effect in some patients. The hormonal changes induced by the medication, specifically the reduction in testosterone, can alter your metabolism and lead to an increase in body fat. Maintaining a healthy diet and engaging in regular physical activity can help manage your weight while on treatment. If you are concerned about significant weight gain, please speak with your healthcare provider.

Trelstar can potentially cause mood swings or emotional changes as a side effect. Hormonal fluctuations are known to affect mood, and because Trelstar works by drastically reducing testosterone, some patients may experience depression, irritability, or other emotional shifts. If you notice significant changes in your mood or mental well-being while taking Trelstar, it is important to report them to your doctor. They can provide support and guidance.

You should discuss alcohol consumption with your doctor before drinking while on Trelstar. Alcohol itself may not directly interact with the medication, but it can worsen some of the potential side effects, such as hot flashes, dizziness, or fatigue. Your doctor can give you personalized advice based on your overall health, the stage of your condition, and any other medications you might be taking to ensure your safety.
