This is an automatically translated article.

Errin, the active ingredient norethindrone, is a type of birth control pill. The drug is prepared in the form of tablets with a content of norethindrone of 0.35 mg.

1. What effect does Errin have?

Errin, used to prevent pregnancy, is often called a "mini-pill" because it doesn't contain any estrogen. The hormone norethindrone, which is a form of progestin, works to prevent conception by making vaginal fluid thicker to prevent sperm from reaching an egg (fertilization) and changing the lining of the uterus (womb) to prevent a fertilized egg stick on. If the fertilized eggs do not attach to the uterus, they will pass out of the body. Errin also blocks the release of an egg (ovulation) for about half of a woman's menstrual cycle. Although Errin is more effective than some other methods of birth control (such as condoms, cervical cap, diaphragm), it is less effective than combined hormone contraceptives (estrogen and progestin). ) because norethindrone does not consistently prevent ovulation. The drug is often used by women who cannot supplement estrogen. To reduce the risk of pregnancy, it is important to take Errin exactly as prescribed. The use of Errin does not protect patients against sexually transmitted diseases (such as HIV , gonorrhea , chlamydia ).

2. How to use Errin

Patients need to carefully read the leaflet provided by the pharmacist before you start using Errin. The leaflet contains very important information about when to take the medicine and what to do if the patient misses a dose. If you have any further questions, ask your doctor or pharmacist for more specific instructions.
Errin is taken by mouth as directed by your doctor, usually once daily. Patients should choose a memorable time of day to take their medication at the same time each day.
Taking Errin after the evening meal or at bedtime may be helpful if the patient experiences abdominal pain or nausea while taking the drug. Patients may choose to take Errin at a different time of day that is easier to remember. Regardless of the dosing schedule a patient uses, it is very important to take Errin at the same time each day, 24 hours apart.
It is best to start taking Errin on the first day of your period. If the patient starts taking the pill on any other day, use an extra form of non-hormonal birth control (eg, condoms, spermicide) for the first 48 hours to prevent pregnancy until when Errin has enough time to work.
Continue to take one pill per day. After taking the last pill in a pack, start a new pack the next day. There is no break between packages, and the patient does not need to take any "reminder" tablets (no pill). The patient's period may be irregular, heavier or lighter than usual. Patients may also experience vaginal bleeding (bleeding) between periods. The patient should not stop taking the drug if this occurs.
Chances of getting pregnant are increased if you miss a pill, start a new pack of pills late, or take your pill at a different time of day than usual. If the patient misses a pill or takes it 3 hours or more later than usual, or has diarrhea or vomiting right after taking the pill, use a backup method of birth control (such as condoms, birth control pills, etc.) spermicide) every time you have sex, for the next 48 hours.
Ask your doctor or pharmacist how to switch from other forms of hormonal birth control (such as the patch, other birth control pills) to Errin. If any information is not clear, refer back to the leaflet or doctor and pharmacist.

3. Drug interactions

Drug interactions can change the way Errin works or increase the risk of serious side effects. The article does not cover all possible drug interactions when using Errin. Patients should keep a list of all products they are taking (including prescription drugs, over-the-counter medicines, and herbal products) and share them with their doctor or pharmacist for advice in the future. Specific case. Patients should not start, stop, or change the dose of any medication on their own without consulting a doctor.
Some medications can make hormonal birth control less effective by reducing the amount of birth control hormones in the patient's body. This effect can lead to an unwanted pregnancy.

Inform the physician when the patient is starting any new medication and discuss whether additional reliable contraception should be used. Also, let your doctor know if you have any new or sudden bleeding, as these could be signs that current birth control isn't working as well.
Errin may interfere with certain laboratory tests (such as sex hormone-binding globulin, thyroid) leading to incorrect test results. Make sure laboratory staff and all doctors know if the patient is taking Errin.
