Topirva XR Topiramate Primidone
MinorAdding Topiramate to Primidone does not usually change the amount of Primidone in your blood in any way that matters. The Primidone level stays steady once you are used to the dose, so you would not normally need a dose change just because Topiramate was started. Still, take both medicines exactly as your doctor has prescribed.
Little or no effect is expected. You usually do not need to change anything, but still tell your doctor or pharmacist about every medicine you take.
