Good evening, I was just perscribed sertraline HCL 50 mg tablets on Thursday. I was directed to take 1/2 tablet daily X one week then increase to one tablet daily. But, I didn t know, so therefore I took a whole tablet on Thursday night. Then Friday night I took a half of tablet. Then I skipped last night. I am having weird side effects like hot flashes, dizziness, drowsiness, and rapid heart patterns. I don t like the feeling at all. Is this because I took them wrong? And should I keep taking them? Thanks
