Hi, I did a strep test on Saturday and it is positive.  Do I absolutely need to take the penicillin that was prescribed? Ive already got celiac disease and am on synthroid and Lamictal so not feeling like adding another medication to the mix. thanks. Shelley
HIT hank for asking to ChatDoctorThe penicillin still is golden therapy for certain bacterial infection like streptococcus, if this is the real situation then you have to take the penicillin for better result, hope this information helps you take care and have good time.
