(ma'' si ten' tan)For female patients: Do not take macitentan if you are pregnant or plan to become pregnant. There is a high risk that macitentan will cause harm to the fetus. Because of the risk of fetal harm, a program called OPSUMIT Risk Evaluation and Mitigation Strategy (OPSUMIT REMS) has been set up to make sure that pregnant woman do not take macitentan, and that woman do not become pregnant while taking macitentan. All females, including females who are not able to get pregnant, can only receive macitentan if they are registered with OPSUMIT REMS, have a prescription from a doctor who is registered with OPSUMIT REMS, and fill the prescription at a pharmacy that is registered with OPSUMIT REMS. Your doctor will register you in OPSUMIT REMS. Your doctor will tell you about the risks of macitentan, especially the risks of serious birth defects if taken while pregnant. You must sign an informed consent sheet stating that you understand this information in order for your doctor to register you. Your doctor will also determine if you are able to become pregnant. If you have reached puberty (when child's body becomes physically mature and capable of having a child), have a uterus, and have not yet gone through menopause ('change in life' end of monthly menstrual periods) you are considered to be a female who is able to become pregnant, and you will have to follow certain additional rules in order to receive macitentan. For females who are able to become pregnant: You must use reliable birth control throughout your treatment with macitentan, and for one month after your treatment. Your doctor will tell you which forms of birth control are acceptable, and will give your written information about birth control. In most cases you will be required to use two forms of birth control in order to prevent pregnancy while taking macitentan. You will have to take a pregnancy test before starting treatment, every month during treatment, and one month after treatment in order to be able to receive macitentan. Your doctor will order the pregnancy tests for you. The pharmacy will not dispense macitentan to you until they have confirmed that you have taken your required pregnancy tests. You must not have unprotected sex while taking macitentan. Call your doctor right away if you have had unprotected sex, think your birth control failed, missed your period, or think you may be pregnant for any reason. He will discuss your medical options with you. Do not wait until your next appointment to discuss this with your doctor. Tell your doctor if you do not understand everything you were told about birth control, or if you do not think you will be able to use acceptable forms of birth control at all times during your treatment. If you are a parent or guardian of a female who had not yet reached puberty, check your child regularly to see if she is developing any signs of puberty (breast buds, pubic hair )and let her doctor know about any changes. For all patients: Macitentan is not available at retail pharmacies. Your medication will be mailed to you from a specialty pharmacy that is registered with OPSUMIT REMS. If you are a female who has not reached puberty or a female who is able to become pregnant you will only receive a 30 day supply at a time. Ask your doctor if you have any questions about how you will receive your medication.
