Cortisone can also cause fetal anencephaly, premature birth and early death. 23.Progesterone and testosterone: cause external genital malformation of the fetus. 24.Vitamin D: large amounts can cause fetal hypercalcemia and retarded intellectual development. 25.Vitamin K: taken in large amounts, can cause hyperbilirubinemia, nuclear jaundice. 26.Vitamin B6: taken in large quantities, can cause vitamin B6 dependence and convulsions in newborns. Vitamin B6 derivatives of the brain, in animal experiments caused by cleft lip, should also be used with caution. 27, multivitamins: if taken during the first trimester, the risk of infants with common neurological deficiencies up to 60%. 28.Proamidine: cause fetal limb deformities. 29, antimalarial drugs quinine, quinoline chloride, ethamidine: can cause hydrocephalus, meningocele, cleft palate, kidney stop development or malformation, retinal damage. 30.Anti-allergic drugs such as paracetamol, mincozine, ankamycin, diphenhydramine, multiplying dizzying and other anti-allergic drugs: in addition to the potential for cleft palate, cleft lip, lack of limbs, but also liver toxicity and brain damage, inhibit neonatal respiration. 31, fluorouracil, cyclophosphamide: can cause fetal limbs, palate, external nose, urinary tract deformities, and death. 32.Aminopterin: cause fetal anencephaly, hydrocephalus, meningeal bulge, cleft lip, cleft palate or limb malformation. 33.Hydroxyurea and leucovorin: cause multiple malformations in fetus. 34.Leucovorin:Causes central nervous system damage and anencephaly. 35.6-mercaptopurine, testosterone propionate, L-mentholatase: cause fetal malformation. 36.Phenylbutyrate nitrogen mustard: can cause renal and ureteral defects. 37.Thiotepa, 5-fluorothiouracil, mitomycin C, colchicine: cause fetal death. It is safer to use these antineoplastic drugs if they are used after the 16th week of pregnancy. 38.Dicoumarins: can cause fetal skin bleeding spots, brain disorder, placental abruption, bone and facial malformation, mental retardation or fetal death. 39.Warfarin: cause abnormal nasal bone development and malformation. 40.Toluenesulfonylurea (methylsulfonylurea, methanesulfonylurea, D860): Causes abortion, premature birth, and has a pro-teratogenic effect. 41.Prothiouracil, methiocarbazole, tapazole, methocarbamol, potassium iodide: cause hypothyroidism, cretinism, delayed ossification, hypospadias. 42.Diphenhydramine or cyclopentaclorothiazide: can cause neonatal thrombocytopenia. 43.Lisperdal: cause neonatal toxicity, nasal congestion, respiratory obstruction, and even death due to hypoxia. 44.Caffeine: Causes cleft lip and palate. 45.Ether: large amounts of continuous use, can cause fetal death. 46.All drugs containing arsenic: all cause fetal death. 47.Polymyxin E, B and vancomycin: if taken for too long, it can cause acute renal failure in pregnant women and make the child susceptible to neuromuscular block, dyskinesia, vertigo, convulsions and abnormal perioral sensation in the 3 years after birth. Vancomycin can also cause temporary or permanent deafness in infants. 48.Rifampicin: Causes fetal malformation. 49.Antifungal drugs amphotericin B, ashwagandha, myclobutanil, clotrimazole: serious adverse reactions to the nervous system, hematopoietic system, liver and kidney function of pregnant women. Ashwagandha also leads to miscarriage and abnormal fetus. 50, Aminopterin (triamcinolone acetonide): there is liver damage and alteration of blood picture for pregnant women. 51.Chlorothiazide: adverse effects on the fetus. 52.Tachyphylline: produce nausea and vomiting, diarrhea, drug rash, itching, blurred vision, postural hypotension and even water and electrolyte disorders to pregnant women and mothers. 53.Lyuric acid: It can cause temporary hearing loss, which sometimes can develop into permanent deafness. 54, other: alcoholic pregnant women can deliver newborns in a withdrawal-like inhibited state; alcohol can cause multiple fetal malformations. The use of contraceptive pills should be completely discontinued after six months before conception, in order to avoid the birth of malformations or dementia caused by improper use of drugs. The above drugs should be banned or used with caution during pregnancy, and those who must use them should do so under the guidance of a doctor. It is important to use a single drug, small dose and short duration.
