Is It Safe to Use Muscle Relaxants for Back Pain? A Real Pharmacist Explains
Back pain can strike anyone—after a long day, sitting at a desk, or doing heavy lifting. Many people turn to muscle relaxant tablets for quick relief. But are these medicines safe? Should you use them every day? As your pharmacist, let’s talk honestly about how and when muscle relaxants can help—and when they can cause more problems than they solve.
What Are Muscle Relaxants and When Are They Used?
Muscle relaxants are medicines (like cyclobenzaprine, tizanidine, or chlorzoxazone) that help relax tight or spasming muscles. Doctors may prescribe them for:
-
Sharp muscle spasms after an injury,
-
Sudden “locking” of the back,
-
Severe lower back pain when basic painkillers (like paracetamol or ibuprofen) are not enough.
They’re usually meant for short-term use—just a few days to a week—alongside rest, gentle movement, and physiotherapy.
Is It Safe to Take Muscle Relaxants Daily?
Short answer:
Muscle relaxants can be helpful for a few days, but daily, long-term use brings real risks.
Why?
-
Long-term use can lead to drowsiness, “brain fog,” poor coordination, or even dependence.
-
They may interact with other medicines (especially sleeping pills or painkillers) and are risky for elderly people, pregnant women, or anyone with liver/kidney issues.
-
Daily use masks the real problem. Back pain often signals poor posture, strained muscles, or a need for physio—not just a pill.
Always use only as your doctor prescribes—and never buy or use muscle relaxants over-the-counter without checking with a pharmacist.
Pharmacist’s Real-Life Experience
In my pharmacy, I often see people coming back for repeat bottles of muscle relaxants. The first few days, the pain gets better—but then, people start feeling groggy, tired, and forgetful, or they notice the medicine stops working so well. I always advise: “Muscle relaxants are a bridge, not a crutch. Let’s get you moving safely, not stuck on tablets!”
Diclofenac and aceclofenac are NSAIDs (painkillers/anti-inflammatories), not muscle relaxants.
They’re used for pain and inflammation—similar to ibuprofen—but they work differently from muscle relaxants (like cyclobenzaprine or tizanidine), which specifically target muscle spasms and are prescribed for short bursts when muscles “lock up.”
That’s why, in the muscle relaxant post, I focused only on true muscle relaxant medicines:
Cyclobenzaprine
Tizanidine
Chlorzoxazone
But your question is super relevant!
Many people use diclofenac or aceclofenac for back pain and think of them as muscle relaxants, when they’re really NSAIDs. That’s why I answered you with a full pharmacist’s comparison right after your question, outlining the purpose, risks, dosing, and safer use of these common painkillers.
Muscle relaxants give quick relief from severe back pain, but daily or long-term use can be harmful. Focus on treating the root cause—movement, stretching, posture—and use these medicines for only the shortest time needed. When in doubt, talk honestly with your doctor or pharmacist for safer, more lasting recovery.
