Lactation is a sensitive period, and like other times, it also involves the issue of medication. However, due to the involvement of breastfeeding for infants, medication safety is a crucial matter. As there are numerous types of medications, not all can be used during lactation. Typically, Nifedipine Sustained-release Tablets are not recommended during this period.

Can Nifedipine Sustained-release Tablets be taken during lactation?

It is not advisable to take Nifedipine Sustained-release Tablets during lactation as they may be secreted in breast milk and passed to the infant. Infants should not take this type of medication. Therefore, if breastfeeding is necessary, it is recommended to discontinue this medication. If, however, due to certain illnesses, this medication is absolutely necessary, breastfeeding should be stopped. In fact, many medications have not undergone clinical studies on infants, and their effects on infants are currently unknown. Typically, calcium channel blockers like Nifedipine are not indicated for use in very young patients, and many medications are contraindicated and lack clinical research. Therefore, if breastfeeding is necessary, Nifedipine and similar medications are not recommended.

Safety Levels of Medication during Lactation

Lactating mothers should pay attention to the safety of medication. The safety levels of medication during lactation are as follows:

L1: Safest

Many lactating mothers have taken the medication without observed increased side effects on infants. No dangers to infants have been confirmed in controlled studies of lactating women, and the potential harm to breastfeeding infants is minimal; or the medication is not orally absorbed or utilized by infants. Medications in this category include acetaminophen, amoxicillin, and ampicillin.

L2: Safer

In limited studies of medication use by lactating mothers, there is no evidence of increased side effects. There is little evidence of risk associated with the use of these medications by lactating mothers. Medications in this category include acyclovir, amikacin, aztreonam, and azithromycin.

L3: Moderately Safe

No controlled studies have been conducted on lactating mothers, but there may be a risk of adverse reactions in breastfeeding infants. These medications or controlled studies have only shown very minor, non-fatal side effects. These medications should only be used when the benefits to the infant outweigh the risks. New medications without published relevant data are automatically classified into this category, regardless of their safety.

L4: Possibly Hazardous

There is clear evidence of harm to breastfeeding infants or breast milk from these medications. However, the benefits of using these medications by lactating mothers may outweigh the risks to infants, such as in life-threatening or severe illnesses where safer medications cannot be used or are ineffective.

L5: Contraindicated

Studies on lactating mothers have confirmed significant harm to infants or a high risk of significant harm to infants from these medications. The use of these medications by lactating mothers is clearly not beneficial. These medications are contraindicated for use during lactation.
