Can drinking amoxilin antibiotitics for sore throat give me a yeast infection if so what should i do?

Possibly: Antibiotics disrupt your normal flora, so it leaves you vulnerable to a yeast infection. You can use any number of topical treatments for this.

Solution: Using over the counter vaginal yeast preparations such as monistat-7 or other similar products can help relieve the symptoms. An easy solution to prevent the problem is to insert about a tablespoonful of plain yogurt intravaginally for a few days to help restore the bacteria which was killed off by the antibiotic.
