Cyclobenzaprine (Flexeril) is commonly used to relieve muscle sprain, and healthcare providers prescribe this drug for short-term usage. However, if you are a lactating woman, you might be concerned about the safety of taking Flexeril when breastfeeding.

Much research has not been done to understand the effects of Flexeril on lactation; however, since the drug can be found in breast milk, you should take it with caution. Usually, doctors prescribe Flexeril to lactating women only after considering its benefits and side effects.

What Is Cyclobenzaprine?

Cyclobenzaprine is a prescription-based skeletal muscle relaxant that helps alleviate muscle pain. It is a short-term treatment course for various muscle injuries such as sprains. It is prescribed with other healing measures such as physical therapies and adequate rest. Cyclobenzaprine relaxes muscles by working on the central nervous system (CNS). It is available in the form of tablets and extended-release capsules.

Flexeril is one of the brand names of cyclobenzaprine. Some other brand names are Amrix, Fexmid, and Comfort Pac-Cyclobenzaprine (1).

There is not enough research on the effects of cyclobenzaprine on human lactation. But the composition of cyclobenzaprine is similar to tricyclic antidepressants such as imipramine or amitriptyline, which are known to interact with breast milk.

The use of tricyclic antidepressants is known to cause sinus tachycardiaⁱXA condition where the heart beats faster than than usual (i.e.,100 beats per minute), arrhythmiasⁱXAbnormal or irregular heart rhythmsand stroke. Therefore, nursing mothers should use cyclobenzaprine with caution (3).

Why Should Flexeril Not Be Taken For Too Long?

Flexeril is a skeletal muscle relaxant used to relax muscles in the body. Typically, these medicines are prescribed for up to three weeks because they haven’t been proven to be effective for muscle problems lasting longer (5). Long-term use may cause persistent exposure to side effects with no gains or benefits from the drug. Moreover, there are concerns that long-term use of skeletal muscle relaxants, such as cyclobenzaprine (Flexeril), may increase the risk of overdose and addiction, leading to related problems (7).

Precautions Of Cyclobenzaprine Use While Breastfeeding

If you are a nursing mother, a thorough risk assessment of the drug before use is essential to ensure its safety and efficacy. Most drugs pass into breast milk, but they may or may not cause harm to your baby.

Here are some cautionary measures to follow if you use cyclobenzaprine while breastfeeding for general pain relief.

• Cyclobenzaprine use will add to the side effects of drugs that are CNS depressants. These are drugs that cause drowsiness by suppressing the nervous system. So if you are taking medicines for colds and allergies, sedatives or any medicine for your sleep problems, any painkillers or drugs for seizuresⁱX A condition resulting in uncontrolled electrical activity in the brain, causing sudden jerking movements in the body , use cyclobenzaprine with extreme caution. These same considerations apply if you use some form of anesthesia during your dental visits and other medicines you might take to relax your injured or tired muscles.

• As a new mother taking care of a small baby, you need to be even more alert than usual. Since the use of Cyclobenzaprine may cause dizziness and drowsiness and suppress your nervous system, disable its use if you find it interfering with the care of your child. Also, practice extreme caution when you drive, use tools or machinery or perform any task that requires extreme attention when you are on cyclobenzaprine. Episodes of dizziness or drowsiness may cause unexpected problems for you and can be extremely dangerous. In addition to increasing your chances of accidents, these problems can pose a danger to the neonatal health and well-being.

• Use of cyclobenzaprine causes the mouth to become dry. If temporary solutions like chewing a sugarless candy or ice cubes don’t provide relief then, increase your water intake. If the problem persists, consult with your dentist for a solution. Not taking care of this problem may lead to dental decay or gum problems, which in turn will necessitate you to take more drugs for your oral health or undergo dental treatments with anesthesia. These potential problems can affect overall maternal health.

• Tell your doctor about any drug allergies you suffer from before taking cyclobenzaprine.

• If you have used any MAO inhibitor (MAOIs), then refrain from using cyclobenzaprine for the next two weeks to avoid harmful drug interaction (1). MAOIs are a type of antidepressant drugs. Some common brand names are Marplan, Parnate and Nardil. Therefore, it is very important not to use your MAOIs without your doctor’s approval when using cyclobenzaprine even if your doctor prescribed you your antidepressants at an earlier time.

Besides these, always take the medicine in recommended dosage to avert the risk of overdosage. Also, share about all the medications that you take before starting cyclobenzaprine to avoid potential drug interactions.
