I m 33, a little over 5 8, weigh around 158 and have had a long medical history. I had anaphylactic (sp?) shock from the antibiotic, Leviquin. I hit my head badly as a child 3 times, 2 times i received stitches. One of them I had amnesia for 3 days after it occured. I have been to many psychiatrists since 10th grade (1994) and have been on many medications.I m wondering whether any of the drugs I m taking now, or have been taking can cause vitamin deficiencies. The drugs are Paxil, Klonopin, Adderall, Lexapro, Hydrocodone, Haloperidol and Zoloft.
