What is Previfem Birth Control Pills?

Previfem is a combination oral contraceptive pill (OCP, birth control medication, birth control pills) that prevents pregnancy by preventing the release of an egg (ovulation), and thickening the cervical mucus, blocking sperm from getting into the uterus and getting to the egg. Previfem is also prescribed to: treat acne, reduce the risk of ovarian cysts (as in polycystic ovarian syndrome [PCOS]), treat painful or heavy periods, and more. Read More

How to Use Previfem

Previfem is super easy to use. Simply take one pill every day, at the same time each day. Many women find that taking Previfem before bedtime or just after their evening meal reduces nausea and other side effects. After taking 21 days of active pills, you’ll switch to seven sugar pills (placebo pills). These are inactive pills with no hormones that are there to keep you in the habit of taking your pill every day.

Previfem Dosage

Previfem uses a combination of two hormones estrogen (Ethinyl Estradiol, 0.035 mg) and progestin (Norgestimate 0.25mg) to make your body think it’s pregnant so a real pregnancy won’t happen.

Benefits of Previfem

Previfem Side Effects

The risks are very low, but some women have experienced unwanted side effects when taking Previfem. Minor ones include breast tenderness, headaches, nausea, swollen feet or ankles, and slightly elevated blood pressure or blood sugar levels. Positive side effects are also a possibility, too — reduced acne, fewer mood swings, and other perks are fairly common.

The chances of serious side effects are extremely unlikely, but some cases have been documented such as blood clotting, shortness of breath, migraines, vision problems, slurred speech, confusion, and fainting. Those who wear contacts or are nearsighted may notice vision problems as well.

These may sound scary, but remember — they’re very rare.
