What to Take for Lower Back Pain: OTC to Prescription

For most lower back pain, an over-the-counter anti-inflammatory like ibuprofen is the best starting point. It’s the recommended first-line treatment for both acute flare-ups and chronic low back pain, and generic ibuprofen is as effective as any pricier alternative. But what you should take depends on how long you’ve been hurting, what kind of pain it is, and what other health conditions you have. Here’s a practical breakdown.

Anti-Inflammatories: The First Choice

NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen and naproxen are the go-to for lower back pain. They reduce both pain and the inflammation driving it. All NSAIDs perform about equally well for back pain, so there’s no reason to reach for an expensive brand. Generic ibuprofen, taken 600 to 800 mg three times daily as needed, is the standard starting approach. It also carries fewer serious stomach side effects than some other NSAIDs.

The American College of Physicians recommends NSAIDs as first-line drug therapy for chronic low back pain that hasn’t improved with non-drug approaches like heat, movement, or physical therapy. That recommendation holds whether the pain is a week old or months old.

If you can’t take ibuprofen, acetaminophen (Tylenol) is a reasonable alternative. It’s slightly less effective for back pain than NSAIDs because it doesn’t target inflammation directly, but it works well enough for many people. The key safety limit: never exceed 4,000 mg of acetaminophen per day (that’s eight extra-strength tablets), as higher amounts risk liver damage. If you drink alcohol regularly, your safe ceiling is even lower.

Who Should Avoid NSAIDs

NSAIDs aren’t safe for everyone. They can worsen kidney function, raise blood pressure, trigger gastrointestinal bleeding, and increase the risk of heart attack and heart failure. If you have chronic kidney disease, heart failure, a history of stomach ulcers, or prior cardiovascular events like a heart attack or stroke, NSAIDs are generally off the table. Acetaminophen or a different class of pain reliever is a safer route for these groups.

Even in healthy adults, NSAIDs are best used at the lowest effective dose for the shortest time needed. A few days to a couple of weeks is typical for an acute back episode.

Topical Options for Localized Pain

If your pain is concentrated in one area, topical treatments let you target it directly with less impact on the rest of your body. Diclofenac gel (sold as Voltaren) is a topical NSAID available over the counter. You rub it directly over the painful spot, and it delivers anti-inflammatory relief locally.

Lidocaine patches provide a numbing effect and can help with several pain qualities, including burning, shooting, and general aching. In clinical use, some patients found them effective enough to reduce or stop other pain medications entirely. Prescription-strength patches contain 5% lidocaine, though lower-concentration versions are available over the counter.

Capsaicin patches are another option. These use the compound that makes chili peppers hot to gradually desensitize pain receptors in the skin. Over-the-counter capsaicin patches (0.025% concentration) can be applied up to three or four times daily for no more than eight hours per application. They work best with consistent use over several days. If pain worsens or doesn’t improve after a week, stop using them.

Muscle Relaxants for Spasm-Related Pain

When your lower back pain involves muscle spasms, the tight, cramping kind that makes it hard to move, your doctor may prescribe a muscle relaxant. These are typically reserved for cases where ibuprofen or acetaminophen alone isn’t cutting it. Common options include cyclobenzaprine, methocarbamol, and metaxalone, all of which work by calming nerve signals in the brain and spinal cord that trigger muscle tightness.

The important limitation: muscle relaxants are only meant for short-term use, generally two to three weeks. None of them have been well studied for chronic use, and they cause drowsiness in most people. They’re a bridge to get you through the worst of an acute episode, not a long-term solution. Expect to feel sleepy, so avoid driving or operating machinery while taking them.

Prescription Options for Chronic Pain

If your lower back pain has lasted three months or more and hasn’t responded to anti-inflammatories, your doctor may consider a prescription medication that works differently. Duloxetine, a medication originally developed for depression and anxiety, has become a recognized option for chronic low back pain. It works by boosting levels of two brain chemicals (serotonin and norepinephrine) that help dampen pain signals traveling up from the spine.

Studies show that 60 mg once daily is the most effective dose for reducing both pain and disability while keeping side effects manageable. A lower dose of 20 mg showed no benefit over placebo, so the dose matters. The American College of Physicians lists duloxetine as a second-line treatment for chronic low back pain, alongside tramadol, when NSAIDs haven’t worked.

Opioids sit at the bottom of the treatment ladder. Guidelines recommend them only after everything else has failed, and only when the potential benefits clearly outweigh the well-documented risks of dependence and side effects.

What About Nerve Pain and Sciatica

If your lower back pain radiates down your leg, you may be dealing with sciatica, which involves a compressed or irritated nerve rather than just sore muscles. This is a different type of pain, often described as shooting, electric, or burning, and it doesn’t always respond to standard pain relievers.

Medications like gabapentin and pregabalin are commonly prescribed for nerve-related pain in other conditions. However, a systematic review of the evidence found a clear lack of effectiveness for both drugs in treating sciatica specifically. Despite being widely used, neither gabapentin nor pregabalin reliably outperformed placebo for leg pain or disability in controlled trials. They also come with notable side effects including dizziness, drowsiness, and nausea. If your doctor suggests one of these, it’s worth discussing the limited evidence.

Supplements Worth Considering

Curcumin, the active compound in turmeric, has anti-inflammatory properties that may help with pain related to joint and musculoskeletal problems. Research suggests doses of 500 to 2,000 mg of curcumin extract per day can reduce pain. Curcumin is poorly absorbed on its own, so look for formulations that include piperine (black pepper extract) or use enhanced-absorption technology.

Magnesium is widely promoted for muscle relaxation, though direct evidence for back pain specifically is limited. Many adults don’t get enough magnesium from their diet, and a deficiency can contribute to muscle tension and cramping. If you suspect that’s a factor, a magnesium supplement is low risk and inexpensive. Supplements are best viewed as a complement to, not a replacement for, proven treatments.

Matching Treatment to Your Pain

The right choice depends on your situation. For a fresh episode of back pain that started in the last few days or weeks, ibuprofen is the clear starting point, with acetaminophen as an alternative. Adding a topical treatment can help if the pain is in a specific spot. If muscle spasms are a major part of the picture, a short course of a prescribed muscle relaxant can help you get moving again.

For pain that has lingered beyond three months, the approach shifts. NSAIDs remain first-line, but if they’re not enough, duloxetine offers a different mechanism that targets the way your nervous system processes pain. Physical therapy and movement remain critical at this stage, and medications work best when paired with them rather than used alone.
