The use of hormonal contraceptives is associated with an increased risk of thromboembolism, myocardial infarction, and a stroke. The risk increases with age, especially in women who smoke a lot (more than 15-20 cigarettes a day). Therefore, women over the age of 35 using TriNessa are strongly advised to quit smoking. Sometimes the increased risk persists for several years after the withdrawal of oral contraception.
The medication does not affect the ability to drive vehicles and work with complex mechanisms.
If you forgot to take a pill, but no more than 12 hours passed, TriNessa remains effective for pregnancy prevention. If the interval exceeds 12 hours, its effectiveness decreases and it is necessary to use additional barrier methods of contraception (such as condoms).
The contraceptive can affect the quantity and quality of milk in the mammary glands. A small amount of hormones can penetrate into the milk. The fact that TriNessa can influence a nursing baby was not proven. However, women should not use oral contraceptives until they stop breastfeeding. Since breastfeeding women are not fully protected from the possibility of becoming pregnant, additional barrier contraception is recommended. The use of hormonal birth control pills in the early stages of pregnancy can cause developmental defects in newborns.
