Your doctor will probably start you on a low dose of phentermine and topiramate and increase your dose after 14 days. After you take this dose for 12 weeks, your doctor will check to see how much weight you have lost. If you have not lost a certain amount of weight, your doctor may tell you to stop taking phentermine and topiramate or may increase your dose and then increase it again after 14 days. After you take the new dose for 12 weeks, your doctor will check to see how much weight you have lost. If you have not lost a certain amount of weight, it is not likely that you will benefit from taking phentermine and topiramate, so your doctor will probably tell you to stop taking the medication.

The problem isn’t a shortage of people wanting to be doctors, but rather, too few opportunities for training. Medical schools have increased class sizes by 30% since 2002, but federal funding for residency training – an essential step in the process of becoming a practicing physician – has not increased since 1997, according to Inside Higher Ed.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with phentermine and topiramate and each time you refill your prescription.

You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.
