Actual product appearance may differ slightly.
Why is this medication prescribed?
Qsymia is a prescription medication used for weight management in adults who are overweight or obese. Qsymia is typically prescribed when diet and exercise alone have not been sufficient for weight loss. Qsymia is a combination of two active ingredients: phentermine and topiramate.
- Phentermine: Phentermine is an appetite suppressant that affects the central nervous system, reducing appetite and increasing the feeling of fullness.
- Topiramate: Topiramate is an anticonvulsant that has been found to have weight loss effects. The exact mechanism by which topiramate contributes to weight loss is not well understood.
How should this medicine be used?
It’s important to note that the specific instructions for using Qsymia can vary based on individual circumstances. Therefore, it’s crucial to follow the prescribing doctor’s instructions and read the medication guide provided with the prescription. However, here are some general guidelines:
- Dosage: Qsymia is usually started at a low dose and gradually increased to minimize side effects. The typical starting dose contains 3.75 mg of phentermine and 23 mg of topiramate extended-release. The dosage may be increased at specific intervals based on the response to treatment.
- Administration: Qsymia is usually taken once daily in the morning with or without food. It should be swallowed whole and not crushed, chewed, or divided.
- Regular Monitoring: Regular follow-up appointments with the prescribing healthcare provider are essential to monitor progress, discuss any side effects, and make adjustments to the dosage if necessary.
- Lifestyle Changes: Qsymia is typically prescribed as part of a comprehensive weight management plan that includes a reduced-calorie diet and increased physical activity.

Before prescribing Qsymia, healthcare providers consider factors such as the individual’s overall health, medical history, and the potential for side effects. If you have questions or concerns about Qsymia, it’s crucial to discuss them with your healthcare provider for personalized advice.
