Can I breastfeed while taking Flexeril?

Understanding Flexeril and Breastfeeding
Flexeril, known generically as cyclobenzaprine, is a muscle relaxant often prescribed to relieve muscle spasms and discomfort. However, when it comes to breastfeeding, many mothers may have concerns about the safety of taking medications like Flexeril.
The Impact of Flexeril on Breastfeeding
According to existing research, cyclobenzaprine is classified as a Category B drug by the FDA for pregnancy. This means that while animal studies have not shown any adverse effects, human studies are limited. The primary concern for breastfeeding mothers is whether Flexeril can pass into breast milk and affect an infant.
Pharmacokinetics and Transfer to Breast Milk
Cyclobenzaprine is metabolized in the liver and has a relatively low oral bioavailability. Studies on the drug’s excretion in breast milk indicate that it does transfer to breast milk but in small amounts. The American Academy of Pediatrics states that cyclobenzaprine is considered compatible with breastfeeding, and the levels found in breast milk are unlikely to cause harm to a breastfeeding infant.
Recommendations for Breastfeeding Mothers
While the consensus suggests that taking Flexeril while breastfeeding is relatively safe, mothers should consider the following:
1. Consult Your Healthcare Provider: Always discuss any medications with your doctor or a lactation consultant. They can provide personalized advice based on your specific situation.

2. Monitor Your Baby: If you start taking Flexeril, monitor your baby for any unusual behavior or signs of sedation, such as excessive sleepiness or difficulty feeding.
3. Timing of Doses: If possible, consider timing your doses of Flexeril after breastfeeding sessions. This could minimize the amount of medication available in your system during feeding times.
4. Alternative Treatments: If you’re concerned about the effects of Flexeril, ask your healthcare provider about alternative treatments for muscle pain that may have a safer profile during breastfeeding.
Conclusion
In summary, while Flexeril does pass into breast milk, the amounts are generally considered low and unlikely to harm a breastfeeding infant. Nevertheless, it is crucial for mothers to engage in an open dialogue with their healthcare providers to ensure the best outcomes for both themselves and their babies. Always prioritize safety and informed choices when it comes to medication use during breastfeeding.

What can I take for muscle pain while breastfeeding?
