I just started Gris-Peg at 3 tablets per day (375 mg total) to handle ringworm on my scalp (which was not responding to other treatment). The Gris-Peg has given me a headache. Will the headaches eventually go away? I'm supposed to take this medicine for 4-6 weeks... and I am hoping that the headache will subside once my body gets used to the drug. Does anyone have any advice from personal experience with this drug? I'm on day 2 of the Gris-Peg and the ringworm feels slightly less inflamed, so I'm hopeful that it will finally get rid of the ringworm.
