Summary
Megestrol is used to treat loss of appetite and weight loss in patients with cancer or AIDS. It helps increase appetite and promote weight gain, improving nutritional status and quality of life. It may also be used for other conditions as determined by your doctor.
Megestrol works by mimicking the hormone progesterone, which helps regulate appetite and weight. It increases appetite and promotes weight gain by enhancing hunger signals, encouraging patients to eat more, thus improving nutritional status and quality of life.
The usual starting dose of Megestrol for adults is 800 mg per day, taken as a single dose or divided into smaller doses. It can be taken with or without food, and tablets can be crushed if needed. Always follow your doctor's specific dosing instructions.
Common side effects of Megestrol include increased appetite, weight gain, and fluid retention. These effects vary from person to person. If you experience new symptoms, talk with your doctor to determine if they are related to Megestrol.
Megestrol can increase the risk of blood clots and cause adrenal suppression, which is when your adrenal glands don't produce enough hormones. It should not be used if you are allergic to it. Always discuss any concerns with your doctor and follow their guidance closely.
