Yohtex, or levonorgestrel tablets, are not usually recommended for women over the age of 40, who are more susceptible to thrombotic disorders, and hormone-containing medications can further increase the risk of blood clots. For these reasons, Yohtex is not usually recommended for women over 40, and the drug’s instructions require it to be taken. Women over 40 are at risk of developing blood clots, and hormone-containing medications can further increase the risk of blood clots. If you have sexual intercourse without contraception, or if you have used a condom but it falls off, breaks, or is removed prematurely during sexual intercourse, you can monitor your HCG closely to prevent unintended pregnancy or use the medication cautiously as prescribed by your doctor. If levonorgestrel tablets have been taken, blood counts, blood clotting and other relevant indicators may be closely monitored to prevent thrombosis. Also, side effects of the drug such as nausea, vomiting and dizziness may occur, and the symptoms usually disappear within 24 hours. There may also be prolonged vaginal bleeding, early or delayed menstruation, which can be observed. If irregular bleeding or severe pain in the lower abdomen occurs, you should consult a doctor to clarify the cause of the problem and take treatment under the doctor’s guidance.
