I am a healthcare worker that suffered a contaminated needle stick on the job. I was seen by a physician within 4 hrs of the stick. During the visit lab was drawn, Chemistry 23 screen, Hepatitis panel (Hep A,B,C, Hep B immune status, HIV and RPR. I was started on Combivar 450mg during the visit, and prescribed Combivar 450mg BID, along with Phenergan 25mg q 12 hr. When can I expect side effects, if any, to begin? I have to return in one week to be seen again. Any information you can provide would be appreciated. Thanks BW
