Seven precautions for preconception medication safety Preconception medication precautions I: Try not to use medication 3 to 6 months before pregnancy both spouses should avoid morphine, chlorpromazine, antipyretic analgesics, ciprofloxacin, ketoconazole, erythromycin, rifampin and other drugs to avoid affecting the quality of fertilized eggs. Pre-conception medication precautions II: Drugs to be used with caution by women Hormonal drugs, certain antibiotics, antiemetics, anti-cancer drugs, sleeping pills, etc., can affect germ cells to some extent. Usually it is safer to conceive after one month of drug withdrawal, but many drugs affect longer. Women with a history of long-term drug use must consult their doctors to determine a safe time for conception. Pre-conception drug precautions three: male caution drugs affecting male sperm quality are antihistamines, anti-cancer drugs, caffeine, morphine, steroids, diuretics, aphrodisiac drugs, etc. These drugs can not only lead to birth defects in newborns, but can also lead to developmental delays and abnormal behavior in infants. The maturation cycle of sperm is about 2 months, try not to take such drugs during this period. Pre-conception medication precautions 4: How long can you stop taking medication to get pregnant If you have been using medicated contraceptive devices and oral contraceptive drugs for a long time, you should stop taking them for 6 months before getting pregnant. However, many drugs affect longer time, the specific situation varies from person to person, please consult your doctor. Pre-pregnancy medication precautions 5: Caution “prohibited for pregnant women” drugs If women need to take their own medication during the planned pregnancy period, they must avoid taking drugs with the words “prohibited for pregnant women” in the drug description. The reason is that Chinese medicine is a compound drug and its effect on the reproductive cells is not easily detected, while many people always believe that Chinese medicine is warm and harmless, and even casually go to pharmacies to grab the medicine for use. If you have taken the medicine without knowing you are pregnant, don’t rush to terminate the pregnancy first. The reason is that there is a relatively safe period for taking medication during pregnancy (three weeks before menopause before the embryo is formed), and some medications have very little effect on the embryo. What you need to do at this time is to inform your doctor in detail about the medication, who can analyze whether it is necessary to terminate the pregnancy based on the type and nature of the medication, the stage of embryo development at the time of medication, the amount of medication and the length of the course of treatment. For the sake of the health of the fetus, the safety of pre-pregnancy medication must be alerted to men and women who are preparing to get pregnant, and it is beneficial to know the above pre-pregnancy medication precautions.
