I'm going to Ivory Coast in January and have just had Hepatitis A & Typhoid jabs; Yellow Fever and Diphtheria follow in 10 days or so. I think these are similar to the India requirements? I asked the same question of the nurse who said "no need to worry, there's no interaction whatsoever". Hmmm, I've been almost permanently hypoglycaemic for the 2 days since the jabs, so I'm not so sure...
