Practical guidance
According to the prescribing information for Topiramate, people with diabetes can usually start Topamax at the standard 25mg, 50mg, 100mg, 200mg dose. Monitoring blood glucose more frequently in the first weeks is sensible. Diabetic complications such as autonomic neuropathy or significant cardiovascular disease may shift the risk-benefit balance and require specialist input.
