Nausea with mild temperature after taking metformin. Side effect or drug interaction with nuva ring?
Patient: I started taking Metformin 1000 mg last Sunday evening. I had no noticeable side effects. I replaced my nuva ring on Thursday and took the metformin as I had been after my evening meal. I started feeling very nauseated the next morning after breakfast and haven t been able to shake it since. I have had a slight temp at 99.5. Could this be an interaction between the two medications? If so, what should I do? Doctor: Hello thank you for your query. Normally, Metformin does have a side effect of nausea. However, there is no specific interaction with Nuvaring. Nuvaring itself is a hormonal substance, and can cause nausea. it could be the additive effect of both medications and not an interaction. You would do best to consult your health care provider, since nausea alongwith a mild temperature could herald the beginning of an infection. Take care.
