| Combined hormone methods of birth control — the pill, the patch, and the ring — should not be used by women who have confirmed and untreated blood pressure over 140 systolic or 90 diastolic.
Women who request prescriptions for combined hormone methods must have their blood pressure checked. If they have somewhat elevated blood pressure, they may be asked to have their blood pressure checked again between three to six months after they first receive their prescriptions. Women who renew their prescriptions after a year of use will also have their blood pressure checked, to make sure their methods are still right for them. |
