When taking Vestura to prevent pregnancy and treat acne, the standard dosage is one tablet taken once a day, at the same time every day. This prescription birth control pill comes in a pack that contains 28 pills. It is important to know exactly what to do if you forget to take any of these pills, as missing doses increases your risk of pregnancy.
An Introduction to Your Dose of Vestura
There is only one standard dose of Vestura™ (drospirenone/ethinyl estradiol). As always, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Vestura Dosing Guidelines
When you take Vestura for the first time, you can start it either on the first day of your period or on the first Sunday after your period starts. If you start Vestura on the first day of your period (a "day 1 start"), you do not need to use any backup method of contraception.
If you choose a "Sunday start," you need to use a backup method of contraception, such as condoms, for the first week. If the first day of your period happens to be on a Sunday, treat this as a "day 1 start" (no backup needed).
If you switch from another type of birth control pill, start taking Vestura on the day you would normally start a new pack of birth control pills; no backup contraception is necessary.
Starting at the beginning of the pack, take one tablet at the same time each day. Each pack will last for 28 days (four weeks). After you finish one pack, immediately start a new one the next day. The first 24 tablets in the pack contain the active ingredients. The last four in the pack do not contain any active ingredients. By taking these last four tablets, your body gets a break from the hormones, allowing you to have a period.
