Mechanism of action

Active substances can slow down ovulation and disrupt the normal course of the secretory phase of the menstrual cycle, resulting in temporary changes in the endometrium and preventing the penetration of a fertilized egg into the uterus.

When taking pills, the viscosity of secretions from the cervical canal increases, making it more difficult for sperm to reach their goal and fertilize the egg. The thickness of the endometrium also decreases, due to which the egg is unable to attach to the walls of the uterus. Due to this complex effect of the drug, fertilization is impossible.

When taking the drug, the ovaries stop doing their work; they are in the resting stage. At the same time, additional changes are observed in the endometrium, cervical canal and fallopian tubes.

special instructions

Before using Ovidon, it is recommended to consult a doctor for the purpose of conducting a gynecological and general medical examination, including examination of the mammary glands using mammography and palpation, cytological analysis of a cervical smear, laboratory testing of liver tests, blood pressure control, determination of sugar levels, hormone analysis .

In women who smoke (especially over the age of 35), the risk of developing cardiovascular complications increases, therefore, before starting to take Ovidon, as well as regularly during its use, medical supervision is necessary.

The drug should be discontinued immediately in the following cases: embolism (feeling of constriction in the chest, pain in the chest when breathing or coughing, unusual pain in the legs, bloating of the veins), thrombophlebitis, thromboembolism, thrombosis, cerebrovascular disorders, sudden hearing and/or vision impairment, exophthalmos, diplopia, new migraine-like headaches, repeated persistent headaches, cholestasis, jaundice, itching, hepatitis, increased frequency of epileptic attacks, porphyria, myocardial infarction, subsequent pregnancy, as well as the development of any severe chronic disease.

If elective surgery is necessary, the drug should be discontinued 6 weeks before surgery.

Patients with diabetes should be aware that Ovidon may alter glucose tolerance.

Diarrhea and vomiting help remove the drug from the body. If these symptoms persist throughout the day, you may need to take an additional tablet. For longer-lasting diarrhea and/or vomiting, it is necessary to temporarily use other methods of contraception.

Reviews

Ovidone is one of the few emergency contraceptive drugs that 100% protects against pregnancy and rarely causes negative effects. I've been using it for 2 years now. During this time I even managed to lose excess weight. My husband and I are planning a child soon, so we’ll have to give up the pills, but I’ll definitely continue to use them.

Irina, 27 years old, Moscow

After taking the pills, I started having severe headaches and nausea. At first I thought that this was my body adapting to the new drug, but when the unpleasant symptoms began to intensify, I consulted a doctor. It turned out that I have increased sensitivity to the components that make up Ovidon, as a result of which another remedy was prescribed.

Anna, 24 years old, Voronezh

I started taking Ovidone after an abortion, since my husband and I were not planning children yet (we already have 4 of them). I am satisfied with the results of use; I only need to take the tablets once a day, preferably in the evening. Only in the first week of taking it I felt a little dizzy, but then everything went away and I took the drug again as usual.

Natalya, 34 years old, Magnitogorsk

I was prescribed medication after giving birth. I took it for 3 years until my husband and I wanted a second child. I can't say anything bad about these pills, as they are really effective and harmless. Their dosage regimen is quite simple - 1 tablet per day. But you shouldn’t take them on your own; it’s better to discuss everything with your doctor. Placental insufficiency during pregnancy causes you will find the answer in the link.

General description of the drug

Ovidon Richter is a monophasic drug based on a complex of two main components: estrogen and gestagen. The medicine is available in the form of white tablets. In total, one blister contains 21 tablets.

The hesterogenic and estrogenic components are completely synthetic, therefore they are more active in comparison with the natural hormones that the female body produces.

The effect of these two synthetic hormones is to stop ovulation. That is, with proper use of the medicine, the ovaries enter a stage of calm. At the same time, some changes occur in the fallopian tubes and cervical canal. After this, the discharge from the cervical canal acquires a more viscous consistency, so sperm cannot move normally. Due to such temporary changes, the likelihood of fertilization is eliminated. However, 100% effectiveness of the contraceptive is possible only if all recommendations that are indicated in the instructions for use of Ovidon are followed.

The active substances contained in the drug are very quickly absorbed in the small intestine. The maximum concentration of active substances in the blood is achieved within a few hours after taking the drug. Please note that 10% of hormones can pass into breast milk. Therefore, the product cannot be used while breastfeeding.
