Qsiva is a medicine that helps you lose weight by reducing your appetite, using two active ingredients, phentermine and topiramate, that work better together.
Your doctor will start you on a low dose, usually 1 Qsiva 3.75 mg/23 mg capsule once a day for 14 days, then typically 1 Qsiva 7.5 mg/46 mg capsule once a day.
Swallow the capsules whole with a glass of water or another sugar-free drink in the morning. Do not crush or chew them. You can take them with or without food.
The highest recommended dose is 1 Qsiva 15 mg/92 mg capsule once daily.
