I should take fevarin 50 mg a day (previously 100 mg), but gradually, of my own free will (without the doctor's knowledge) I got to 200 mg a day, which I take on the 4th day and I am much better than at 50 or 100 mg . I plan to increase the dose to 300 mg a day. Is it safe to increase the dose of SSRI antidepressants like this without the doctor's knowledge?
