The main components of Xiao Su Jiuxin Pill are Chuanxiong and Borneolum Syntheticum. Long-term use of borneol and other drugs will consume qi and injure yang, leading to the decline of heart function. Therefore, it is necessary to pay attention to the dose not being too large and the medication time not being too long, so as to avoid adverse reactions. The initial dose should be small, usually 4 capsules, and should be placed under the tongue when taking it. If you want it to take effect faster, you can chew it up and put it under your tongue, and it will take effect directly after being absorbed by the mucosa. Never swallow it, because it is absorbed by gastrointestinal tract after swallowing, and its effect is slow, and its efficacy is greatly reduced, so it can't play a therapeutic role.

If the symptoms are not relieved after 10 minutes, you can take it again; If it is still not relieved after taking it twice, the possibility of acute myocardial infarction should be considered and immediately sent to the nearest hospital for rescue.

When taking Xiao Su Jiuxin Pills sublingually, if there is no pungent and cold feeling of the drug, it means that the drug has failed and should be stopped and replaced.

When taking quick-acting jiuxin pills, it is best to sit in a sitting position. Because if you stand with clothes on, your head is high, and your blood pressure often drops due to vasodilation, causing dizziness, dizziness and even syncope; It is also inappropriate to take medicine in a prone position, because a large amount of blood returns to the heart, which makes the heart burden heavier and it is difficult to control the symptoms.
