<s>[INST] I have diverticulitis and was prescribed ciprofloxacin. Once I finished my prescription I got a really bad yeast infection. It's been 3 weeks and I still itch. I also take metformin....sometimes because it makes my heart beat fast. So I stop taking it. But I'm tired of this rash.....what should I do? [/INST] Thanks for your query at HCM!I am Infectious Disease Specialist! I went through your query!Please continue your metformin and consult your physician before stopping. Describe your lesions in detail? Which part?Apply topical clotrimazole cream twice daiy for 7 days. Single stat dose of oral fluconazole is also the treatment for a candial infection.Also intake of oral antihistamine like either cetrizine, fexofenadine or loratadine(10mg once)  once or twice dailyHappy to take more queries! You can also write a review for me. If you would like some more information, I will be happy to provide. You can take a follow-up query.Take care!Dr. Sheetal VermaInfectious Disease Specialist </s>
