Which medication is known to cause hair loss, loss of appetite, and nausea as side effects?

The medication known to cause hair loss, loss of appetite, and nausea as side effects is Methotrexate. This medication is a chemotherapy agent and immunosuppressant often used to treat certain types of cancer, autoimmune diseases, and ectopic pregnancies.

Hair loss is a well-documented side effect of various chemotherapy agents, including Methotrexate, as it affects rapidly dividing cells, such as those in hair follicles. Additionally, due to its mechanism of action, Methotrexate can lead to gastrointestinal side effects, including nausea and loss of appetite, as it can irritate the lining of the stomach and intestines.

The other medications listed vary significantly in their side effect profiles. Doxorubicin, another chemotherapy agent, can also cause hair loss but is more commonly associated with cardiotoxicity and other specific side effects. Azithromycin, an antibiotic, does not typically cause hair loss and is more associated with gastrointestinal upset and potential allergic reactions. Baclofen, a muscle relaxant, is primarily linked to drowsiness and dizziness rather than the symptoms mentioned.

Understanding the side effects associated with each medication is crucial for patient care, as it allows healthcare professionals to monitor and manage adverse reactions effectively.
