[|Human|] Hi on the same day I started microgynon 30 at night I had to start clarithomycin 500mg every 12 hours for a UTI, usually 7/8am and pm. I have vomited every night. This is my third day in both. Which is making me sick? Should I keep taking both. Many thanks in advance.
[|AI|]  Hi, Vomiting is a common side effect of both. Moreover, azithromycin may reduce the efficacy of microgynon.  If you are using microgynon for birth control, you may be at increased risk for pregnancy or breakthrough bleeding.  So you should use an alternative or additional form of birth control during or after treatment with azithromycin. Vomiting can be minimized by taking these Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further. Take care
