Megace is primarily used to help address appetite loss and weight loss linked to serious medical conditions.
- Appetite loss associated with cancer

Because treatment goals vary, a clinician decides whether it is appropriate based on the person’s condition and overall health.

The original content states that the typical starting dosage is 800 mg per day, which may be given as a single dose or divided doses depending on the patient and the prescriber’s instructions.

How can Megace interact with other medications?
The source content highlights possible interactions with medications used for diabetes. Because Megace may raise blood sugar, people taking diabetes medicines may need closer monitoring.
The original content also mentions anticoagulants and antidepressants as medicines to tell a healthcare provider about. A full medication review is important, including prescription drugs, over-the-counter products, and supplements.
What precautions should be discussed before using Megace?
Before treatment, the source content says patients should discuss their medical history, especially if they have:

Regular follow-up is important so a clinician can monitor response and any side effects. The original content also notes that blood sugar monitoring may be needed.

The source content states that Megace is contraindicated during pregnancy and is not recommended during breastfeeding. It also notes that women of childbearing age may be advised to use effective birth control while receiving treatment.
If pregnancy is possible or breastfeeding is ongoing, this should be discussed with a healthcare professional before treatment decisions are made.
What are the possible long-term effects?
The original content says long-term use may be associated with metabolic changes, persistent weight gain, and hormone-related effects. It also notes possible risks such as diabetes or cardiovascular issues in some studies.
Because long-term effects can vary, ongoing monitoring and regular review with a clinician are important.
When should a patient seek medical advice?
Medical advice should be sought promptly if there are signs of a serious reaction, unusual weakness, dizziness, severe fatigue, or symptoms that seem to worsen after starting treatment.
Any new or concerning symptom should be reviewed by a healthcare professional, especially in people with diabetes or other ongoing medical conditions.
