Trinessa Lo Review


TriNessa Lo is a combination of female hormones (norgestimate and ethinyl estradiol) used as a contraceptive to prevent ovulation and pregnancy.

Contents:

Indications for use

  • Oral contraception.

Mechanism of action

The active components of the drug suppress the release of gonadotropins, prevent the maturation of eggs in the ovaries and ovulation. In addition, the drug increases the viscosity of cervical mucus, which complicates the penetration of sperm into the uterus, and acts on the endometrial epithelium, reducing the likelihood of implantation.

Dosage and mode of application

Each pack of TriNessa Lo contains 28 tablets: active tablets are white (Day 1-Day 7), light blue (Day 8-Day 14) and dark blue (Day 15-Day 21). Inactive tablets are dark green (Day 22-Day 28).

The drug is taken orally. Take 1 tablet every day for 28 days in a row, without breaks. The interval between doses of the drug should not exceed 36 hours. Contraceptive pills are most effective when taken at the same time of day, for example, in the evening. Once you’ve finished the pack, start a new one immediately.

Overdose

An overdose of TriNessa Lo (norgestimate and ethinyl estradiol) can cause vomiting, nausea, and vaginal bleeding. There is no specific antidote. In case of overdose, it is necessary to do a gastric lavage (within the first hour after taking the active pill) and to receive symptomatic therapy.

  • Cardiovascular system: arterial hypertension, myocardial infarction, cerebrovascular accident, deep vein thrombosis, arterial thromboembolism, pulmonary or other thromboembolism, edema;

Interactions

  • The metabolism of norgestimate and ethinyl estradiol is enhanced by Hypericum perforatum, barbiturates, carbamazepine, phenytoin, sulfonamides, derivatives of pyrazolone, rifampicin;
  • When taken together with some antibiotics (for example, ampicillin or tetracycline), there is insufficient cleavage of estrogen conjugates and fatty acids by intestinal bacteria;
  • Some protease inhibitors and some antiretroviral drugs (indinavir, ritonavir) can increase or decrease the concentration of combined hormonal contraceptives in the blood;
  • When taken with hypoglycemic drugs, a patient may require their dose adjustment.

Pregnancy and breastfeeding

TriNessa Lo is contraindicated for use in pregnant women.

Epidemiological studies did not reveal an increase in the risk of birth defects in children whose mothers took norgestimate and ethinyl estradiol tablets before pregnancy. In most modern studies, the teratogenic effects, in particular, heart abnormalities and shortening of the extremities, were not found in the offspring of women who mistakenly took COCs during pregnancy.

The medication can affect lactation (reduce the amount and change the composition of breast milk). In addition, a small portion of the drug components can penetrate into breast milk. In this regard, TriNessa Lo is contraindicated for use during breastfeeding.

What if I miss a pill?

If you miss 1 active tablet in Week 1, 2 or 3, take the tablet as soon as you remember. If you miss 2 active tablets in Week 1 or Week 2, take 2 tablets the day you remember and 2 tablets the next day; and then take 1 tablet per day until you finish the pack. In addition, you should use a non-hormonal method of contraception such as a condom or spermicide if you have sexual intercourse in the next 7 days. If you miss 2 active tablets in Week 3 or miss 3 or more active tablets in a row, continue taking 1 tablet per day until Sunday. On Sunday, throw out the rest of the tablets and start a new pack that same day. In addition, you should use a non-hormonal method of contraception such as a condom or spermicide if you have sexual intercourse in the next 7 days.
