You'll still need to focus on diet and exercise while taking these drugs, and they're not for everyone.
Doctors usually prescribe the best diet pills only if your BMI is 30 or higher, or if it's at least 27 and you have a condition that may be related to your weight, like type 2 diabetes or high blood pressure.
Here's what you should know about the most common prescription best diet pills: orlistat, Belviq, Contrave, Saxenda, phentermine, and Qsymia.
Before you get a diet pills prescription, tell your doctor about your medical history. That includes any allergies or other conditions you have; medicines or supplements you take (even if they're herbal or natural); and whether you're pregnant, breastfeeding, or planning to get pregnant soon.
