There are many side effects of ephedra, mainly caused by the irrational application of ephedra, such as nausea, headache and so on. For example, if patients have digestive tract problems such as nausea, vomiting, diarrhea, etc., they should be treated symptomatically with drugs that protect the gastric mucosa, such as omeprazole, methylphenidate, etc., which can be taken orally to reduce the symptoms. In case of headache and anxiety, consider resting the patient in a quiet environment and applying medications to relieve vasospasm. The side effects of ephedra also include heart problems, especially in middle-aged and elderly people, which can cause arrhythmias and even increased blood pressure to the point of heart damage, and at this time, antihypertensive drugs should be used, and medications such as metoprolol should also be used so that the rapid heart rate can gradually decrease and the insufficient blood supply to the heart can be improved. If ephedra is applied in too large a dose (excessive side effects), I personally think that it is best to be observed and treated in the hospital so that the side effects can be better resolved.
