Tri-Previfem is a combination hormonal contraceptive pill that contains three active ingredients: norgestimate, ethinyl estradiol, and ferrous fumarate. It is used to prevent pregnancy by inhibiting ovulation, changing cervical mucus, and altering the lining of the uterus.

Like any medication, Tri-Previfem is associated with certain risks and side effects. Common side effects may include nausea, headache, breast tenderness, and changes in weight. However, there are more serious risks that should be considered, such as:

  • Blood Clots: Use of combination hormonal contraceptives like Tri-Previfem increases the risk of blood clots, which can lead to serious conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), heart attack, or stroke.
  • Cardiovascular Issues: Women over 35 who smoke are at an increased risk of cardiovascular events while taking Tri-Previfem. It is generally not recommended for women who smoke and are over 35 years old.
  • Cancer Risk: Some studies suggest a slightly increased risk of breast and cervical cancer in women using hormonal contraceptives. However, the overall risk is still considered low.
  • Liver Problems: Hormonal contraceptives can affect liver function, and in rare cases, they may lead to severe liver problems.
  • Hypertension: Tri-Previfem may cause an increase in blood pressure, and regular monitoring is recommended.
  • Migraines: Women who suffer from migraines, especially with aura, may have an increased risk of stroke while using Tri-Previfem.

It’s crucial to discuss your medical history, including any pre-existing conditions, with your healthcare provider before starting any contraceptive pill. Your healthcare provider can help assess the potential risks and benefits based on your individual health profile. If you experience severe side effects or complications while taking Tri-Previfem, it’s important to seek medical attention promptly.

Why is this medication prescribed?

Tri-Previfem [DSC] is a combination oral contraceptive, often referred to as a birth control pill. It is prescribed to prevent pregnancy by inhibiting ovulation (the release of an egg from the ovary), changing the cervical mucus to make it more difficult for sperm to reach the egg, and altering the lining of the uterus to make it less receptive to a fertilized egg.

The medication contains three active ingredients: norgestimate and ethinyl estradiol, which are synthetic forms of the hormones progesterone and estrogen, respectively. The combination of these hormones helps regulate the menstrual cycle and prevent pregnancy when taken correctly.

How should this medicine be used?

It’s essential to follow your healthcare provider’s instructions when using Tri-Previfem [DSC]. Typically, the medication is taken once daily, at the same time each day, for 28 days in a row. The pack contains three different types of tablets:

  • Active tablets (white, light blue, and dark blue): These contain the active hormones and should be taken consecutively for 21 days.
  • Inactive tablets (green): These do not contain hormones and are taken for the remaining 7 days of the cycle. Menstruation usually occurs during this time.

To use Tri-Previfem [DSC] effectively:

  • Start the first tablet on the first day of your menstrual period or as directed by your healthcare provider.
  • Take one tablet daily at the same time, with or without food.
  • Follow the sequence of tablets in the pack, taking the active tablets first and then the inactive ones.
  • If you miss a dose, follow the package instructions or consult your healthcare provider. Additional contraceptive measures may be necessary if you miss tablets.
  • It’s crucial to take the pills consistently for them to be effective. Missing doses or taking them at irregular intervals may increase the risk of unintended pregnancy.

Always consult your healthcare provider for personalized advice, and inform them about your medical history and any other medications you are taking, as some drugs may interact with Tri-Previfem [DSC].

Other uses for this medicine

Tri-Previfem [DSC] is primarily prescribed as a contraceptive, but it may also have some non-contraceptive benefits. These may include:

  • Regulating Menstrual Cycles: Tri-Previfem [DSC] can help regulate menstrual cycles, making them more predictable and potentially reducing symptoms of premenstrual syndrome (PMS).
  • Reducing Menstrual Cramps: Some women may experience a reduction in the severity of menstrual cramps while taking Tri-Previfem [DSC].
  • Treating Acne: Tri-Previfem [DSC] may have a positive effect on acne for some individuals by regulating hormones that contribute to skin oil production.
  • Decreasing Blood Loss and Anemia: By stabilizing the menstrual cycle, Tri-Previfem [DSC] may help reduce the amount of blood lost during menstruation, potentially lowering the risk of iron-deficiency anemia.

What special precautions should I follow?

As for special precautions when using Tri-Previfem [DSC], consider the following:

  • Medical History: Inform your healthcare provider about your complete medical history, including any history of blood clots, stroke, heart disease, high blood pressure, liver disease, or certain types of cancer.
  • Interactions with Other Medications: Some medications, including certain antibiotics and anticonvulsants, may interact with Tri-Previfem [DSC]. Inform your healthcare provider about all medications, including over-the-counter drugs and herbal supplements, that you are taking.
  • Smoking: Smoking while using Tri-Previfem [DSC] increases the risk of serious cardiovascular side effects, especially in women over 35 years old. It is generally advisable to quit smoking while taking oral contraceptives.
  • Blood Clot Risk: Women who use hormonal contraceptives, including Tri-Previfem [DSC], may have a slightly increased risk of blood clots. This risk is higher in individuals with certain risk factors.
  • Monitoring: Regular check-ups with your healthcare provider are essential to monitor for any potential side effects and ensure the continued appropriateness of the contraceptive method.

Always follow your healthcare provider’s advice and guidance for the safest and most effective use of Tri-Previfem [DSC]. If you have any concerns or experience side effects, contact your healthcare provider promptly.

What special dietary instructions should I follow?

Tri-Previfem [DSC] can be taken with or without food. There are no specific dietary restrictions associated with its use. However, it’s always a good idea to maintain a healthy and balanced diet for overall well-being.

What should I do if I forget a dose?

If you forget to take a dose of Tri-Previfem [DSC]:

  • Missed One Active Tablet: Take the missed tablet as soon as you remember, even if it means taking two tablets on the same day. Then continue taking one tablet daily at the regular time. No additional contraceptive measures are necessary.
  • Missed Two or More Active Tablets in a Row in Week 1 or Week 2: Take the most recently missed tablet as soon as you remember, and then take the next tablet at the regular time. Discard the other missed tablets. Use additional contraception (e.g., condoms) for the next 7 days.
  • Missed Two or More Active Tablets in a Row in Week 3, or Missed Three or More Tablets in a Row in Any Week: Finish the active tablets in the current pack, omitting the missed tablets. Start a new pack the next day. Use additional contraception for the next 7 days.

What side effects can this medication cause?

Tri-Previfem is a combination hormonal contraceptive pill, and like any medication, it may cause side effects in some individuals. Common side effects include:

  • Signs of Blood Clots: Seek medical attention if you experience symptoms such as severe headache, sudden shortness of breath, chest/jaw/left arm pain, weakness on one side of the body, or slurred speech, as these could be signs of a blood clot.
