Common side effects of mitotane and what issues should be paid attention to during use

Mitotane is a targeted drug used to treat adrenocortical cancer (ACC). It inhibits hormone synthesis by selectively destroying adrenocortical tissue, thereby achieving anti-cancer effects. Although the drug has significant effects on some patients, it is also accompanied by a series of side effects that cannot be ignored during the treatment process.

The most common side effects mainly include gastrointestinal reactions, such as nausea, vomiting, loss of appetite, and diarrhea. These symptoms often appear in the first few weeks of starting treatment and may affect the patient's quality of life and medication compliance. In addition, the adverse reactions of the nervous system are also more prominent, such as dizziness, decreased concentration, memory loss and even mood swings. Some patients develop central nervous system effects such as ataxia after long-term medication.

Because mitotane has the characteristics of suppressing adrenal function, it may also cause secondary adrenal insufficiency, leading to fatigue, hypotension, electrolyte imbalance and other problems, which usually require the supplementation of corticosteroid drugs to counteract it. When using mitotane, special attention should be paid to changes in liver function, because the drug is mainly metabolized by the liver, and elevated liver enzymes or hepatotoxicity may affect drug safety.

During the course of taking medication, it is necessary to regularly monitor blood drug concentration, liver function and hormone levels in order to adjust the dosage and deal with side effects in a timely manner. In addition, since this drug is a cytotoxic drug, gloves must be worn when handling tablets to avoid drug powder contacting the skin or inhalation. Women of childbearing age should also take effective contraceptive measures because medications may have adverse effects on the fetus.

In summary, although mitotane is an important treatment, its safe use must be carried out under the guidance of a professional doctor, and the treatment process must be closely monitored to minimize risks.
