Whether or not you can take dydrogesterone tablets after vaccination needs to be decided according to the patient’s specific situation. Dydrogesterone tablets are progestin drugs, mainly used for the treatment of dysmenorrhea caused by progesterone insufficiency, irregular menstruation, miscarriage due to progesterone deficiency and other diseases, and after taking them, adverse reactions such as vaginal bleeding, headache, dizziness and so on may occur. If you are taking dydrogesterone tablets to regulate menstruation, the vaccination has little effect on the drug, and generally speaking, there is no contraindication to taking dydrogesterone, and the vaccination does not affect the medication. If you need to take vaccination during the period of taking dydrogesterone tablets, you should consult your doctor first to avoid adverse reactions.
