Taking amoxicillin for strep throat, is vaginal itching and strange discharge a side affect because i feel a little weird down there ?

Yes, it may be.: Antibiotics alter the normal bacteria in the vagina and can cause yeasts to grow, causing thrush. This presents with itching and altered discharge. You can see your physician to prescribe treatment.

Possible Yeast: Sometimes antibiotics can promote yeast type vaginal infections. Yogurt/probiotics can help. If persistent do have it checked.
