Generally, thickening of the endometrium occurs after the patient starts taking Tegretol and increases with the duration of the drug. Tegretol is a man-made estrogen that helps the endometrium to grow and helps the gestational sacs to settle. Therefore, sometimes during pregnancy preparation, if a woman’s lining is thin, her doctor will prescribe Tegretol to promote the growth of the lining of the uterus, which will help the fertilized egg to implant. If the thickness of the endometrium is slightly thinner than normal, you can usually take oral supplement Glaxo for seven days in order to grow the endometrium. However, if the thin lining is caused by previous uterine adhesions or endocrine system disorders, it may take several months to take Tocopherol. Therefore, it is important to follow the doctor’s instructions and not to use the medicine blindly. In addition, it should be noted that women must be reviewed regularly during the period of taking the drug, because if the endometrium is too thick, it will not work, so you need to follow the doctor’s advice to take the right amount.
