Some muscle relaxers are considered safe during breastfeeding, but consulting a healthcare provider is essential before use.
Understanding Muscle Relaxers and Breastfeeding Safety
Muscle relaxers are medications designed to relieve muscle spasms, stiffness, and pain. They are often prescribed after injuries, surgeries, or for chronic conditions like back pain or multiple sclerosis. However, if you’re breastfeeding, the decision to take any medication requires extra caution. The question “Can I Take A Muscle Relaxer While Breastfeeding?” isn’t straightforward because the safety depends on the specific drug, dosage, and individual circumstances.
Breastfeeding mothers worry about passing harmful substances to their babies through breast milk. Some medications can affect an infant’s development or cause side effects such as drowsiness or feeding difficulties. Therefore, understanding which muscle relaxers are safer and how they behave in breast milk is critical.
How Muscle Relaxers Work and Their Potential Risks During Lactation
Muscle relaxers primarily act on the central nervous system (CNS) or directly on muscles to reduce spasms and discomfort. There are two main categories:
- Centrally Acting Muscle Relaxants: These include drugs like cyclobenzaprine, methocarbamol, and carisoprodol. They work by depressing CNS activity.
- Direct-Acting Muscle Relaxants: Such as dantrolene, which acts directly on muscle tissue.
Because many of these drugs affect the CNS, they can potentially cause sedation or other neurological effects in nursing infants if transferred through breast milk.
The risk varies depending on factors like:
- The amount of drug secreted into breast milk.
- The infant’s ability to metabolize and eliminate the drug.
- The dosage and frequency of the medication taken by the mother.
Some muscle relaxers have limited data regarding their safety during breastfeeding because clinical trials often exclude lactating women.
Common Side Effects of Muscle Relaxers in Breastfed Infants
Though rare, potential side effects in infants exposed via breast milk may include:
- Drowsiness or excessive sleepiness
- Poor feeding or difficulty latching
- Irritability or fussiness
- Respiratory depression in severe cases (very rare)
These symptoms underscore why professional guidance is necessary before starting any muscle relaxant while nursing.
Evaluating Specific Muscle Relaxers: Safety Profiles During Breastfeeding
Not all muscle relaxants carry equal risk during lactation. Here’s a closer look at commonly prescribed options:
| Muscle Relaxer | Breastfeeding Safety | Key Considerations |
|---|---|---|
| Cyclobenzaprine (Flexeril) | Use with caution; limited data available. | May cause sedation in infants; short-term use preferred. |
| Methocarbamol (Robaxin) | Generally considered safer. | Minimal transfer to breast milk; low infant exposure risk. |
| Tizanidine (Zanaflex) | Avoid unless prescribed by doctor. | Lack of sufficient data; potential for CNS depression in infants. |
| Carisoprodol (Soma) | Avoid during breastfeeding. | Metabolizes into meprobamate; risk of sedation and dependency concerns. |
| Dantrolene (Dantrium) | Caution advised; consult healthcare provider. | Poorly studied; possible effects on infant liver function unknown. |
This table highlights that methocarbamol tends to be favored when a muscle relaxer is necessary during breastfeeding due to its lower passage into breast milk.
Methocarbamol: The Preferred Option?
Methocarbamol has a relatively short half-life and low oral bioavailability in infants. Studies suggest that only small amounts reach breast milk, making it less likely to cause adverse effects. This makes methocarbamol a common choice when treatment cannot be delayed.
Still, even with methocarbamol, monitoring your baby for unusual sleepiness or feeding problems is wise.
The Role of Dosage and Timing in Minimizing Infant Exposure
If you must take a muscle relaxer while breastfeeding, timing doses strategically can reduce infant exposure. Here’s how:
- Take medication right after nursing: This allows time for drug levels in your blood—and consequently breast milk—to decrease before the next feeding session.
- Avoid nighttime doses: To prevent peak drug concentration coinciding with overnight feedings when monitoring is more difficult.
- Use lowest effective dose: Minimizing dosage reduces the amount passed into milk without compromising pain relief.
- Lactation “pump and dump” isn’t usually required: Since most muscle relaxers don’t accumulate extensively in milk over time but consult your doctor for specific guidance.
These strategies help protect your baby while you manage your symptoms effectively.
LactMed Database: Trusted Resource for Medication Safety
The LactMed database from the National Library of Medicine offers up-to-date information about drugs and breastfeeding safety. It includes data on drug levels found in breast milk and reported infant effects.
Before starting any muscle relaxer, check LactMed or discuss findings with your healthcare provider to make an informed decision tailored to your situation.

Frequently Asked Questions
Can I take a muscle relaxer while breastfeeding safely?
Some muscle relaxers are considered safe during breastfeeding, but safety depends on the specific medication and dosage. Always consult your healthcare provider before using any muscle relaxant to ensure it won’t harm your baby.
What are the risks of taking a muscle relaxer while breastfeeding?
Muscle relaxers can pass into breast milk and may cause drowsiness, poor feeding, or irritability in infants. Severe effects like respiratory depression are very rare but possible, so professional advice is essential before use.
Which muscle relaxers are safer to take while breastfeeding?
Centrally acting muscle relaxants like cyclobenzaprine or methocarbamol have varying safety profiles. Direct-acting agents like dantrolene may be preferred in some cases. Your doctor can recommend the safest option based on your condition.
How do muscle relaxers affect breastfed infants?
Muscle relaxers may cause sedation or neurological effects in nursing babies due to transfer through breast milk. The infant’s ability to metabolize the drug influences side effects, which is why monitoring and medical guidance are important.
Should I stop breastfeeding if prescribed a muscle relaxer?
Not necessarily. Many muscle relaxers can be used safely with proper medical supervision. Never stop breastfeeding without consulting your healthcare provider, who can help balance treatment needs with infant safety.
The Bottom Line – Can I Take A Muscle Relaxer While Breastfeeding?
The answer hinges on the specific medication involved—some muscle relaxers like methocarbamol appear relatively safe under medical supervision; others should be avoided entirely due to potential risks.
Always consult your healthcare provider before starting any muscle relaxant during lactation. Careful selection of medication type, dose management, timing around feedings, plus vigilant monitoring of your baby’s behavior will help ensure safety for both mom and child.
Remember: non-drug therapies often provide effective relief without risking infant exposure to unwanted chemicals.
Taking control of pain responsibly means balancing effective treatment with protecting your precious little one’s health — now that’s smart parenting!
