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.

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).

Quick fact

Cyclobenzaprine should be used for a short duration that is not more than 2 to 3 weeks, as its safety and efficacy for prolonged use are unclear (2).

Is It Safe To Take Flexeril While Breastfeeding?

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 tachycardiaⁱA condition where the heart beats faster than than usual (i.e.,100 beats per minute) , arrhythmiasⁱAbnormal or irregular heart rhythms and stroke. Therefore, nursing mothers should use cyclobenzaprine with caution (3).

Expert says

According to the US National Library of Medicine, nursing mothers can take Cyclobenzaprine (with caution) as the amount of the drug that passes into the breast milk is minute (4).

What Is The Cyclobenzaprine Dosage When Breastfeeding?

If you are breastfeeding, your doctor will prescribe a dosage to suit your situation. In general, the recommended dosage for a non-breastfeeding person is three doses per day, with each dose of 5 milligrams (5). Do not take the medicine without consulting your doctor first.

Here are some side effects of cyclobenzaprine.

• Difficulty in breathing/chest tightness.

• Puffiness around the eyes

Even if you do not suffer from any of the above side effects while taking cyclobenzaprine, but experience a sense of unease or any other problems after its use, consider it a potential health risk and tell your doctor or a pharmacology expert about it. It will help avert any adverse effect of the drug on your well-being and infant development.

Point to consider

Nursing mothers on cyclobenzaprine should monitor the baby for sedation and developmental milestones, especially in neonates and preterm babies (4).

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 seizuresⁱ 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.

Be watchful

Although uncommon, cyclobenzaprine can cause allergic reactions in sensitive individuals. Seek medical help if you experience symptoms such as hives, wheezing, swelling of the mouth, and/or fever (8).

Several women consider taking painkillers when breastfeeding to alleviate the pain caused by a muscle injury. However, if you are not keen on using any drug, ask your doctor for any natural and safe treatments you can use during this time.

Here are some measures you can use after your muscle injury for effective pain management.

• Immediate use of ice or cold packs on the injured area is helpful for all types of muscle injuries.

• Avoid the use of heat packs for at least 72 hours after your injury.

• Certain herbs, spices, or nutrients have anti-inflammatory properties and are beneficial for inflammatory problems such as pain and swelling. Some examples are turmeric, fish oil, green tea, and Resveratrol (a compound found in foods such as red grapes). Ask your doctor if you can safely use these food sources while breastfeeding (9).
