Key Facts About Demulen

Some drugs may make Demulen less effective in preventing a pregnancy, including antibiotics, hepatitis C medications, HIV/AIDS medications, seizure medications, or barbiturate sedatives. You should tell your doctor about all of the other medications you take.

Demulen does not protect you from sexually transmitted diseases, including HIV and AIDS. The only way to prevent these diseases is to use a condom. If your sexual partner develops HIV or a sexually transmitted disease while you are using Demulen, or if you have any change in sexual relationships you should tell your doctor right away.

You may need to use back up birth control, like a condom, when you first start using Demulen or if you miss a dose.

Demulen is in Pregnancy category X. If you are pregnant, think you may be pregnant, or are breastfeeding you should not use Demulen. We do not know if Demulen may harm your baby in utero.

Directions for Using Demulen

Use Demulen exactly as your doctor has prescribed you to. Do not use it in larger or smaller amounts or for shorter or longer than recommended. Demulen comes with patient instructions for you so you can use this medication safely and effectively. Be sure to follow these instructions carefully.

You will take your first Demulen pill on the first day of your period, or on the first Sunday after your period begins. You may need to use back-up birth control, like a condom, when you first start using Demulen.

You should take one Demulen pill every day, but no more than 24 hours apart. Be sure to get your prescription refilled before you run out of Demulen.

If you miss 1 dose of Demulen you should take it as soon as you remember and then take your next dose at the regular time. This means you may take 2 doses on the same day. If you only miss 1 pill you do not need to use backup birth control, like a condom. If you miss more than 1 active dose of Demulen you should read the extra patient leaflet that comes with your prescription or contact your doctor for instructions. You will need to use a backup method of birth control if you miss more than 1 active dose of Demulen.

The Demulen 28 day birth control pack will contain 7 “reminder” pills to keep you on your regular cycle. Your menstrual cycle will normally begin while you are using these “reminder” pills. You will begin taking your next pack of Demulen pills the day after you have finished your last “reminder” pill, regardless of whether your menstrual cycle has stopped or not.

If you miss one of the 7 “reminder” pills, it is fine. Continue taking one pill a day on your schedule, but throw out the “reminder” pill that you missed to avoid confusion. You do not have to use back-up birth control if you miss a reminder pill.

It is normal to experience breakthrough bleeding, especially during the first 3 months of treatment with Demulen. Tell your doctor if you have bleeding that is heavy or continues daily throughout the month.

If you become ill with severe vomiting or diarrhea you should use back-up birth control.

Store Demulen at room temperature and away from both moisture and heat.
