I agree, to be on the safe side, call your pharmacist. When my neuro recommended I slowly titrate up my dosage, I added 100mg every few days. You should gradually increase up to the point that you get maximum
relief. That might be 600mg, 3x per day, or it might be less, or you might need more. The max recommended safe dosage is 3600 mg per day, which is the dosage I currently am on, (1200mg x 3) with no side effects.
