Drug Information and Safety

LactMed aims to provide evidence-based information about the safety of medications during lactation. This includes evaluating the potential risks and benefits of drug use for both the mother and the infant.

Evaluating Drug Safety During Lactation

Evaluating drug safety during lactation is a complex process that involves considering various factors, including the drug’s properties, the mother’s health, and the infant’s age and health status.

Drug Properties: Factors like the drug’s chemical structure, molecular weight, and route of administration can influence how much of the drug is transferred into breast milk and reaches the infant.
Mother’s Health: The mother’s medical condition, the severity of her illness, and the potential risks associated with not taking the medication are crucial considerations.
Infant’s Age and Health: The infant’s age, developmental stage, and any pre-existing medical conditions can influence their susceptibility to potential drug effects.

Factors Considered When Assessing Potential Risks to Infants

When assessing the potential risks of drug exposure to infants through breast milk, several factors are considered.

Drug Concentration in Breast Milk: The amount of drug present in breast milk is a key factor in determining the potential risk to the infant.
Infant’s Exposure: The amount of breast milk the infant consumes and the frequency of breastfeeding influence the infant’s overall exposure to the drug.
Infant’s Metabolism: The infant’s ability to metabolize and eliminate the drug from their system is also a significant factor.
Potential Adverse Effects: The potential adverse effects of the drug on the infant are carefully evaluated based on available data and studies.
