Product details

Tri-Previfem is a hormone-based contraceptive pill combining progestin and estrogen that helps to prevent pregnancy by tricking your body into thinking that it is already pregnant. We at Nurx™ are big fans because, in addition to birth control,  Tri-Previfem can make periods lighter and can treat acne. Tri-Previfam is not right for you if you are pregnant, breastfeeding, or use tobacco and are older than 35 years. Our team at Nurx can prescribe Tri-Previfem at special request, or can offer the generic equivalent Tri-Sprintec for as low as $0 with insurance or as little as $15 without insurance. Let our experts work with you to find the pill that’s right for you.

  • Is Tri-Previfem Easy to Get?

    Definitely! It's available at most pharmacies, but you will need a prescription. Here at Nurx™, we make it easy by partnering with local doctors in every state where we work. Work with our experts to find which birth control prescription is right for you. It's private, safe, and discrete.

    We accept a number of different insurance providers and are always working to expand the list. Tri-Previfem is also sold under the names Sprintec, Mononessa, Previfem, Ortho Tri-Cyclen, and Ortho Tri-Cyclen Lo.

  • What Precautions Should I Take Before Starting Tri-Previfem?

    As with any prescription medication, you should talk to your doctor or one of our professionals before you begin taking Tri-Previfem. Your pharmacist or doctor can help you understand whether you're at risk of having an allergic reaction, even though the likelihood is low.

    You should also let your doctor know whether you have a history of blood clotting disorders, cancer, diabetes, depression, and any other relevant medical history.

  • Are There Any Known Side Effects?

    Like any other hormone-based birth control, Tri-Previfem does have some documented side effects. These could include headaches, nausea, vomiting, breast tenderness, weight change, or vaginal bleeding. It may also raise your blood pressure.

    More serious side effects are rare but possible. These include mental/mood changes, lumps in the breast, unusual changes in vaginal bleeding, yellowing eyes/skin, or dark urine. In very rare cases it can cause serious problems like blood clots. Tell your doctor right away if you notice symptoms of an allergic reaction.

    It's important to remember that many who use Tri-Previfem do not have serious side effects. Of course, it also has some positive side effects, like increased menstrual regularity and decreased menstrual pain.

  • Can I Take Tri-Previfem With Other Medications?

    In general, the answer is yes. However, interactions with other drugs are possible and they may also reduce the effectiveness of Tri-Previfem. Keep track of all of the medication you take and don't change your dosages without your doctor's permission.

    Other products that could interact with Tri-Previfem include ospemifene, tamoxifen, and certain combination products that are used to treat chronic hepatitis, as well as aromatase inhibitors, tizanidine, and tranexamic acid.

  • Does Tri-Previfem Treat Acne?

    The short answer is yes! Treatment of acne is one of Tri-Previfem's side effects. Talk with your doctor or one of our experts to learn whether Tri-Previfem is right for you and your skin.

  • Does Birth Control Cause Weight Gain?

    It is a common misconception that hormonal birth control is likely to cause weight gain. In fact, recent studies have discovered that this is a myth. When it was first invented, hormonal birth control had much larger doses of hormones that could lead to weight gain. However, today hormonal birth control comes in lower doses.
