Disease analysis: If you care about scars, you can do a skin repair. Generally speaking, Eupatorium adenophorum will not have any adverse reactions. If the patient's tolerance dose is exceeded or the drug is taken excessively, especially because the dose is increased too fast at the beginning of treatment, the following clinical symptoms of hyperthyroidism may occur, including tachycardia, palpitation, arrhythmia, angina pectoris, headache, muscle weakness and spasm, flushing, fever, vomiting, menstrual disorder, pseudotumor, tremor, restlessness, insomnia, hyperhidrosis and weight. In the above cases, the daily dose of the patient should be reduced or the drug should be stopped for a few days. Once the above symptoms disappear, patients should cautiously restart drug treatment. For some people with allergies, allergic reactions may occur. It is worth mentioning that Perrin can not treat hypothyroidism, but as an artificial hormone to supplement the deficiency of thyroid secretion. Long-term use of Eupatorium adenophorum seriously increases myocardial oxygen consumption and increases the burden on the heart and kidneys, so patients taking Eupatorium adenophorum should be accompanied by heart disease and edema. Suggestion: Pregnant women should not take medicine in principle. Perrin belongs to hormonal drugs. I suggest you go to the obstetrics and gynecology department of the hospital to find a doctor and determine the treatment plan during pregnancy.
