Pregnancy Drug Contraindications: According to the degree of harm to the fetus and pregnant women caused by drugs, they can generally be classified as "use with caution" and "prohibited use". Some drugs that can harm the fetus and cause abortion should be avoided during pregnancy, which are called pregnancy drug contraindications.
1. Use with caution: Most of these drugs have the properties of promoting blood circulation, relieving stagnation, removing qi obstruction, and promoting smooth delivery. They should be avoided as much as possible unless there is a special necessity. Examples include peach kernel, safflower, achyranthes, cyperus, rhubarb, mirabilitum, aconite, dried ginger, cinnamon, hawthorn fruit, malva nut, and houttuynia cordata, etc. Whether it is a prohibited or a cautionary drug, if a pregnant woman suffers from a severe illness and cannot be treated without using the above-mentioned drugs, the main contradiction should be grasped, and the drugs should be used judiciously to quickly and cautiously eliminate the pathogenic factors, which is more beneficial to the health of both mother and child. This is the reason for having a reason to use the drugs without causing harm.
2. Prohibited use: Most of these drugs have strong toxicity or have drastic effects such as purgation, blood-activating, and dispersing. Examples include scorpion, croton seed, radix trichosanthis, Chinese rhubarb, rhizoma homalomenae, radix et rhizoma rhei, yanhusuo, leech, blister beetle, Chinese lacquer, tribulus terrestris, cardamom, and musk, etc.
