Previfem is an oral contraceptive made of two hormones — estrogen and progestin — that work together to prevent pregnancy. Previfem prevents ovulation (release of an egg) while thickening the vaginal fluid to make it more difficult for fertilized eggs to attach to the uterus.
Previfem is highly effective when it is taken at the same time each day in a continuous cycle of active and inactive tablets. Right now, Nurx™ does not carry Previfem.
- How Does Previfem Work?
Previfem is a tablet that is taken at the same time each day. A blister pack of Previfem contains 28 active tablets and 7 inactive tablets. You take a color-coded active Previfem tablet once a day for 21 days, then you take a color-coded placebo (inactive) tablet for 7 days. Start a new pack when you finish the previous pack whether or not you have your period.
Previfem is more than birth control, and the hormone combination in Previfem makes it an effective acne fighter. It is important to take Previfem at the same time every day. Choose a time that's easy to remember (set a reminder on your phone), and if you miss a dose, use backup birth control for the next week or two.
- Is Previfem Easy to Get?
Previfem requires a doctor visit for a prescription for this medication. Previfem may be covered by insurance, so check with your provider.
- What Precautions Should I Take Before Starting Previfem?
When considering any type of medication, it's a good idea to talk to your doctor about your health history and to discuss the best birth control options for you.
Speak with your doctor if you have a history of blood clot disorders, since Previfem may increase your risk for stroke or heart disease. If you have diabetes, Previfem may elevate blood sugar levels, so it's wise to monitor your sugar intake regularly. Previfem does not protect against HIV or other STDs.
Allergic reactions to Previfem are rare. Let your doctor know right away if you experience trouble breathing, a rash or itching, or swelling of the throat or tongue while taking Previfem.
- Are There Any Known Side Effects?
Hormonal birth control sometimes comes with common side effects. Most women who experience side effects have reported nausea, vomiting, headache, bloating, or breast tenderness. Fluid retention or weight fluctuations have also been reported and usually lessen over time. Allow yourself some time to adjust to the medication, but let your physician know if symptoms are persistent.
Approximately 1 percent of Previfem users report serious side effects such as continuous spotting or sudden heavy bleeding.
Long-term use of Previfem has shown it can lead to a reduction in the development of ovarian cysts. Also, its hormone combination makes it effective at treating mild to moderate acne.
- Can I Take Previfem With Other Medications?
Previfem can interfere with the metabolism of some medications and supplements. Talk to your doctor if you're taking medications for Hepatitis C or HIV. Let your doctor know about all the medications and supplements you're taking to make sure this medication is compatible with your meds or treatments.
- Does Previfem Stop Your Period?
No, although you might experience some period changes when you first start taking Previfem. Consistent and regular use of Previfem can have positive effects on your period and period symptoms. You may notice your periods become lighter and less painful, but they won't stop altogether.
- Can I Get Pregnant on Previfem?
No birth control is 100 percent effective, but with consistent use, Previfem is a highly effective form of birth control. If you become pregnant or decide to become pregnant, talk to your doctor about stopping Previfem.
