There is no single "best" pill to increase appetite that is universally suitable for everyone, as the ideal choice is dependent on the underlying reason for poor appetite. A healthcare provider will assess a patient's medical history to determine the most appropriate and safest treatment path. Appetite-stimulating medications are generally reserved for significant, medically-related appetite loss and not for casual weight gain.
FDA-Approved Prescription Options
Two of the most well-known FDA-approved medications for appetite stimulation are typically used for specific, chronic conditions like AIDS-related anorexia and cachexia. These include:
- Megestrol Acetate (Megace®): This synthetic progestin hormone is approved to treat loss of appetite and severe weight loss in AIDS patients. It is also sometimes used off-label for similar conditions related to cancer.
- Dronabinol (Marinol®, Syndros®): A synthetic form of THC (delta-9-tetrahydrocannabinol), this cannabinoid is approved for AIDS-related anorexia that causes weight loss. It is also used to treat chemotherapy-induced nausea and vomiting.
Off-Label Medications Used for Appetite Stimulation
Many other medications are not officially approved as appetite stimulants but have increased appetite as a side effect. Doctors may prescribe these off-label, especially when other medical needs overlap with poor appetite.
Mirtazapine (Remeron®)
An atypical antidepressant, mirtazapine is widely known for having increased appetite and subsequent weight gain as a common side effect. For this reason, it is sometimes prescribed off-label to patients experiencing appetite loss, especially when depression is also a factor. Studies have shown mirtazapine can be effective in increasing energy intake.
Cyproheptadine (Periactin®)
As a first-generation antihistamine, cyproheptadine is used off-label to stimulate appetite due to its antiserotonergic effects on the feeding center in the brain. It has been shown to be effective and generally well-tolerated, particularly in children, but is also used in adults with poor appetite.
Corticosteroids (Prednisone, Dexamethasone)
Weight gain is a known side effect of corticosteroids, which can stimulate appetite by mimicking the hormone cortisol. While sometimes used off-label for appetite stimulation in cancer patients, they are generally reserved for short-term use due to significant side effects associated with long-term therapy, such as muscle wasting and increased blood sugar levels.
Dietary Supplements and Natural Options
For individuals with deficiencies, certain vitamins and minerals can help restore appetite, but they are not a substitute for addressing the underlying cause. Common supplements include:
- Zinc: A zinc deficiency can lead to appetite loss and changes in taste perception. Supplementation may help those with a confirmed deficiency.
- Thiamine (Vitamin B1): Low levels of thiamine can cause a reduced appetite. Supplementing can correct this and improve intake.
- Fish Oil (Omega-3s): Some research suggests that omega-3 fatty acids may help increase appetite and reduce feelings of fullness.
- Herbs and Spices: Traditional medicine and naturopathy use bitter herbs like gentian and wormwood to stimulate digestive enzymes and improve appetite. Carminative herbs like ginger, fennel, and peppermint can also help by improving digestion and reducing bloating.

Important Considerations Before Seeking an Appetite Pill
Before starting any medication, it is crucial to consult a healthcare professional. Here are key points to consider:
- Identify the Root Cause: Loss of appetite is a symptom, not a diagnosis. It can be caused by underlying conditions such as infections, chronic disease, mental health issues, or other medications. A doctor will perform tests to determine the best course of action.
- Evaluate Side Effects: Every medication carries risks. For instance, megestrol carries a risk of blood clots, while dronabinol can affect mental and behavioral health. Your doctor can help you weigh these risks against the potential benefits.
- Consider Non-Pharmacological Strategies: Medications should be used as part of a comprehensive care plan. Simple lifestyle changes and dietary adjustments can also be highly effective. These include eating small, frequent meals, incorporating nutrient-dense foods, and engaging in light exercise, which can naturally boost appetite. A dietitian can provide personalized guidance.
Conclusion
There is no one best pill to increase appetite for all individuals. The most appropriate choice is highly individualized and must be determined in consultation with a healthcare provider. While FDA-approved drugs like megestrol and dronabinol exist for specific conditions, other medications like mirtazapine and cyproheptadine are used off-label. A proper medical evaluation is essential to diagnose the cause of appetite loss and select a safe and effective treatment strategy that may also incorporate supplements or lifestyle changes. For reliable information on medications and their uses, resources like the Cleveland Clinic website are valuable tools.
