Daysee is a combination drug that contains female hormones that prevent ovulation (the release of an egg from an ovary). Daysee also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Daysee is used as contraception to prevent pregnancy.

Daysee may also be used for purposes not listed in this medication guide.

Peginterferon beta-1a injection is used to treat the relapsing forms of multiple sclerosis (MS). This medicine will not cure MS, but it may slow some of the disabling effects and decrease the number of relapses of the disease. Peginterferons are natural substances that are produced in the body to help fight infections. Peginterferon beta-1a is a synthetic (man-made) version of these substances.

This medicine is available only with your doctor's prescription.
