Like all forms of oral contraceptives, Levora birth control is extremely effective for preventing pregnancy. Oral contraceptives are 99 percent effective with perfect use and 91 percent effective with “typical” use.
If you begin taking Levora within five days of starting your period, you’ll be protected right away. If you start at any other point in your cycle, you should use another contraceptive method for seven days.
If you miss a pill, take it as soon as you remember. If you miss two or more pills in a pack, use a backup method (such as condoms) for seven days. You should also use a backup method if you start your new pack late (by 48 hours or more).
Certain medications can make oral contraceptives less effective. HIV drugs, anti-seizure medications, Rifampin, Griseofulvin, and St. John’s Wort can all interact with the pill. Make sure your doctor is familiar with any other prescriptions you’re taking so he or she can make sure you’re protected.
As with all oral contraceptives, Levora birth control does not protect against sexually transmitted infections (STIs). You can reduce your risk of contracting or transmitting an STI by using a latex or polyurethane condom every time you have sex.
