Additional details were received as follows: This case was previously reported to a doctor. The patient was positive for Antinuclear antibody. The patient experienced an event to either RABAVERT vaccine or HYPERRAB when receiving them for post-exposure prophylaxis. HYPERRAB was administered in her finger, arm and buttocks. The patient was treated at the hospital because of the rabies exposure but not admitted. She could barely drive home due to her dizziness. The patient's fingers were swelled to twice their size and then resolved after 30 minutes. The patient's throat also swelled and resolved after a few days. Her arms and hands went numb and this numbness resolved after about an hour. She got dizzy and fell back onto the table. She is still experiencing tinnitus, dizziness and a feeling of being off balance. The patient believed most of the events began immediately after receiving RABAVERT and HYPERRAB. The patient underwent Nuclear magnetic resonance test and treated with ALEVE for some events for which, doses were based on her weight of 148 pounds. The patient believed that one of RABAVERT and HYPERRAB caused the reported events and was not receiving any subsequent doses.
