1. What diseases does Mifeviha 10 treat?
Mifeviha 10 has the main ingredient Mifepristone 10mg, this is an Antiprogestin that prevents pregnancy by acting before the implantation of a fertilized egg. The drug works to slow down ovulation. In addition, the drug also works to block the support of the endometrium if taken after ovulation and affects the implantation of a fertilized egg.
Mifepristone also has a progesterone receptor binding affinity. In the presence of progesterone, Mifepristone acts as a competitive receptor antagonist at the progesterone receptor. In the absence of a progeston, Mifepriston acts as a local antagonist. Mifepriston therefore helps to prevent the effects of progesterone on the endometrium, thereby degrading and shedding the lining to prevent or disrupt the attachment of the fetus.
At a dose of 10mg, Mifepriston works to prevent ovulation for 3-4 days, so it works as an emergency contraceptive.
Women who are less than 8 weeks pregnant, taking 150-200mg of Mifepriston in combination with 400-600mcg of Misoprotol has an abortion effect. At that time, Mifepriston has the effect of causing the placenta to detach from the endometrium, helping the cervix to soften, allowing the pregnancy to come out.

6. Precautions when using Mifeviha 10
Mifeviha 10 is not a substitute for regular birth control therapy. Should be used with caution in patients with mild asthma or chronic obstructive airways disease, cardiovascular disease or anemia. Use with caution in patients taking anticoagulants because Mifeviha 10 increases the risk of major bleeding. Having unprotected intercourse after treatment increases the risk of an unwanted pregnancy. Pregnant women: If a pregnant woman takes Mifeviha 10 by mistake with a dose of 10mg, it will not cause miscarriage but the possibility of bleeding can not be ruled out in some cases. Lactation: Mifepristone passes into breast milk, so breast-feeding should be avoided after taking the drug. Drivers, operating machines: The drug does not affect the ability to drive or use machines. Overdose: In all cases of acute poisoning due to overdose, the patient should be hospitalized for monitoring and advanced treatment in special conditions.
7. Drug interactions
Mifepristone metabolism is mediated by the cytochrome P450 enzyme system, CYP3A4, so use of drugs that inhibit or induce this enzyme may lead to changes in Mifepristone concentrations. Ketoconazole, Erythromycin itraconazole and fruit juice (grape juice) can block the catabolism of Mifepristone (increased Mifepristone serum concentration). Rifampicin, Dexamethasone and some antiepileptic drugs (Phenytoin, Phenobarbital, Carbamazepine): Increases the metabolism of Mifepristone, leading to a decrease in serum drug concentrations. Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the contraceptive effect of Mifepristone. Above is information about uses, dosage and precautions when using Mifeviha 10 medicine. To ensure safety for your health and maximize the effectiveness of your treatment, you need to take Mifeviha 10 exactly as directed in the package or as directed by your doctor/pharmacist.
