Take Yaz exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take Yaz in larger or smaller amounts or for longer than recommended. Take your first 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, such as condoms with spermicide, when you first start using this medication.
Take one pill every day, no more than 24 hours apart. When the pills run out, start a new pack the following day. You could get pregnant if you do not take one pill daily.
You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.
If you need major surgery or will be on long-term bed rest, you may need to stop using Yaz for a short time. Any doctor or surgeon who treats you should know that you are using this medicine.
Store Yaz at room temperature away from moisture and heat.
 Detailed Yaz dosage information
What happens if I miss a dose?
Follow the patient instructions provided in your Yaz packet. Ask your doctor or pharmacist if you do not understand these instructions. Missing a pill increases your risk of becoming pregnant.
If you miss 1 active pill;
Take it as soon as you remember. If you do not remember until the next day, take 2 pills at once. Use back-up birth control (such as condoms) for 7 days.
If you miss 2 active pills in a row;
During weeks 1-2, take 2 pills on the day you remember and 2 pills the next day. Then take 1 pill daily until the pack is finished. Use back-up birth control (such as condoms) for 7 days.
During weeks 3-4, throw out the rest of the pack and start a new pack of pills the same day. Use back-up birth control (such as condoms) for 7 days.
