Can Karbis contribute to reducing the number of migraines? Can Karbis affect the effect of contraceptive pills?

Kandesartan (the active ingredient in Karbis) is under investigation for the preventive treatment of migraine. In one study, the number of headache days per month after three and six months of treatment was significantly lower than at the beginning (in 1/3 of patients, the number of migraines per month was reduced by up to half). Karbis does not affect the effectiveness of birth control pills.
