The said dose may be increased up to 300 milligrams in a day after a week of use. If pain persists after 2-4 weeks of continued treatment at 300 milligrams of Lyrica per day, the dose may be then increased to 300 milligrams taken twice per day, or a milder dose of 200 milligrams for three times in a day.
