There is no single best medication for spinal arthritis because the right choice depends on which type you have and how severe your symptoms are. For the most common form, spinal osteoarthritis, anti-inflammatory drugs called NSAIDs are the first-line treatment recommended across major guidelines. For inflammatory spinal arthritis like ankylosing spondylitis, NSAIDs are also the starting point, but biologic therapies become essential when inflammation persists. Here’s how the main options compare.
NSAIDs: The First Choice for Most People
Nonsteroidal anti-inflammatory drugs work by blocking the enzymes that produce inflammation in your joints. They reduce both pain and stiffness, which makes them more effective than simple painkillers for arthritis in the spine. Common over-the-counter options include ibuprofen and naproxen, while prescription-strength options include diclofenac and celecoxib.
Not all NSAIDs perform equally. A large network meta-analysis found that diclofenac at its full prescription dose was the most effective NSAID for osteoarthritis pain and physical function, outperforming ibuprofen, naproxen, and celecoxib at their maximum doses. Etoricoxib, a selective anti-inflammatory available in many countries outside the U.S., also showed strong results. If you’ve tried ibuprofen without much relief, a different NSAID may work better for you.
The American College of Rheumatology strongly recommends NSAIDs for active ankylosing spondylitis and does not favor one specific NSAID over another for that condition. For people with active inflammatory spinal arthritis, continuous daily use is preferred over taking them only when pain flares. Once the disease stabilizes, switching to as-needed use is reasonable.
Why Acetaminophen Falls Short
Many people reach for acetaminophen (Tylenol) first because it feels like the safer option. But research consistently shows it performs poorly for arthritis. A meta-analysis comparing NSAIDs to acetaminophen in osteoarthritis found that NSAIDs were significantly better at reducing both resting pain and walking pain. One expert review went further, concluding that acetaminophen had no clinically meaningful effect on osteoarthritis symptoms and should not be recommended for it. If you’ve been relying on acetaminophen alone and your spinal arthritis pain isn’t improving, this is likely why.
Topical NSAIDs: Similar Relief, Fewer Side Effects
Topical diclofenac, available as a gel or solution, delivers anti-inflammatory medication directly through the skin. Multiple head-to-head trials in osteoarthritis have shown that topical NSAIDs provide equivalent pain relief, stiffness reduction, and functional improvement compared to oral NSAIDs. In one trial of 622 patients, topical diclofenac improved pain by 44% versus 49% for oral diclofenac, meeting the threshold for equivalence. A pooled analysis found that about 55% of patients achieved meaningful pain reduction with topical NSAIDs compared to 56% with oral versions.
The key advantage is dramatically lower systemic absorption. Topical diclofenac puts roughly 6% of the applied dose into your bloodstream, resulting in plasma levels about 17 times lower than the oral form. That translates to fewer stomach, heart, and kidney concerns. The tradeoff is that topical formulations work best for joints close to the skin surface. The spine is deeper, so topical NSAIDs may be less effective for spinal arthritis than for knee or hand arthritis, though they can still help with superficial muscle and soft tissue pain around the spine.
Long-Term NSAID Risks to Know About
Spinal arthritis is a chronic condition, and long-term NSAID use carries real risks. These drugs are associated with a 25% increased risk of cardiovascular events, including heart attack and stroke. They can also cause stomach ulcers, gastrointestinal bleeding, and kidney damage over time. Selective COX-2 inhibitors like celecoxib were originally designed to be gentler on the stomach, but they turned out to carry their own elevated cardiovascular risk.
This doesn’t mean you should avoid NSAIDs. It means you and your prescriber should weigh the benefits against your personal risk factors: your age, blood pressure, kidney function, history of stomach problems, and how long you’ll need the medication. For many people, using the lowest effective dose for the shortest necessary period is the practical approach. Others may need continuous treatment and can manage the risks with protective strategies like adding a stomach-protecting medication.
Biologics for Inflammatory Spinal Arthritis
If your spinal arthritis is inflammatory, meaning conditions like ankylosing spondylitis or axial spondyloarthritis, NSAIDs alone often aren’t enough. When they fail to control symptoms, biologic therapies become the next step. The ACR strongly recommends TNF inhibitors for people with active ankylosing spondylitis that hasn’t responded to NSAIDs.
TNF inhibitors block a specific inflammatory protein driving the disease. Options in this class include adalimumab, etanercept, infliximab, golimumab, and certolizumab. A second class, IL-17 inhibitors, includes secukinumab and ixekizumab. A systematic review and network meta-analysis confirmed that both TNF inhibitors and IL-17 inhibitors were significantly more effective than placebo at achieving meaningful improvement in symptoms. JAK inhibitors, a newer class of oral medications, have also shown effectiveness.
One important distinction: conventional disease-modifying drugs like methotrexate, sulfasalazine, and leflunomide do not work for spinal involvement. They may help with peripheral joint symptoms in some cases, but they have no meaningful effect on inflammation in the spine itself. Combining methotrexate with a biologic also hasn’t been shown to improve outcomes for spinal disease.
Nerve Pain Medications for Spinal Stenosis
Spinal arthritis can cause bone spurs and narrowing of the spinal canal, a condition called spinal stenosis. When this compresses nerves, the resulting pain is different from joint inflammation. It’s a shooting, burning, or tingling pain that radiates into the legs, sometimes accompanied by weakness or difficulty walking longer distances.
Pregabalin and gabapentin work by calming overactive nerve signals. A meta-analysis of their use in spinal stenosis found that pregabalin produced a significant reduction in pain scores at three months, though no meaningful improvement was seen in the first eight weeks. Functional disability scores didn’t improve significantly. Side effects were substantially higher in the medication group. About one in three people taking these drugs at standard doses experiences dizziness or drowsiness, and the overall rate of adverse events was nearly six times higher than placebo.
These medications can be worth trying when nerve compression is the primary pain driver, but the evidence is mixed and the side effects are common enough that many people stop taking them.
Spinal Steroid Injections
Epidural steroid injections deliver anti-inflammatory medication directly to the irritated nerve roots in your spine. They don’t treat the arthritis itself, but they can provide significant relief from nerve-related pain. For people with a new disc herniation or acute nerve compression, injections may resolve symptoms completely. For chronic spinal arthritis, the typical duration of relief is three to six months.
The general recommendation is no more than three to six injections per year. For acute problems, injections can be spaced just weeks apart. For ongoing management, spacing them three to six months apart is more common. These injections work best as part of a broader plan that includes physical therapy and other treatments rather than as a standalone solution.
Muscle Relaxants for Acute Flares
Spinal arthritis flares often trigger painful muscle spasms around the affected joints. Muscle relaxants like metaxalone, baclofen, and cyclobenzaprine are sometimes prescribed for short-term relief during these episodes. The evidence supporting their use is limited, and most studies have only tested them for one to two weeks. Benzodiazepines like diazepam have not shown meaningful pain benefits in the available research. Even short-term use of muscle relaxants commonly causes drowsiness and dizziness, so they’re best reserved for brief flares rather than ongoing management.
Matching Treatment to Your Type of Spinal Arthritis
The most important factor in choosing medication is getting the right diagnosis. Spinal osteoarthritis, the wear-and-tear type, responds to NSAIDs and topical anti-inflammatories. Inflammatory spinal arthritis requires NSAIDs first and often biologics to control the underlying immune process. Nerve compression from spinal stenosis may need a completely different approach with nerve-calming medications or injections. Many people have overlapping causes, which is why a combination of treatments often works better than any single medication.
