There is no single best medication for spinal arthritis because the right choice depends on the type of arthritis you have, how severe your symptoms are, and how your body responds to treatment. Spinal arthritis generally falls into two categories: osteoarthritis (wear-and-tear degeneration of the joints and discs) and inflammatory arthritis (where the immune system attacks the spinal joints). Each type responds to different medications, and most people end up using a combination rather than relying on one drug alone.
NSAIDs: The Standard Starting Point
Anti-inflammatory drugs like ibuprofen, naproxen, and celecoxib are the most widely used first-line medications for both types of spinal arthritis. They reduce pain and swelling at the same time, which makes them more effective for joint-related pain than a simple pain reliever. For osteoarthritis of the spine, over-the-counter doses of ibuprofen or naproxen are often enough to manage mild to moderate flares. Celecoxib is a prescription alternative that targets inflammation more selectively and is generally easier on the stomach.
The catch with NSAIDs is long-term use. Taking them daily for months or years raises the risk of stomach ulcers, kidney problems, and cardiovascular events like heart attack or stroke. If you need an NSAID regularly, using the lowest effective dose for the shortest time possible is the safest approach. Your doctor may add a stomach-protecting medication if daily use becomes necessary.
Acetaminophen for Mild Pain
Acetaminophen (Tylenol) is sometimes used for spinal arthritis when inflammation isn’t the main problem or when NSAIDs aren’t safe for you. It relieves pain but does nothing for swelling, so it’s less effective overall for arthritis compared to NSAIDs. For chronic use, it’s safest to stay at or below 3,000 mg per day, even though the absolute maximum for healthy adults is 4,000 mg. People who drink alcohol regularly or have any liver concerns need to be especially cautious, since acetaminophen is processed by the liver and doses near the upper limit can be toxic.
Duloxetine for Chronic Back Pain
Duloxetine is an antidepressant that also works on chronic pain by boosting the activity of serotonin and norepinephrine, two brain chemicals involved in the body’s pain-dampening system. It’s approved for chronic musculoskeletal pain, including low back pain, at a dose of 60 mg once daily (sometimes starting at 30 mg for the first week). This makes it a useful option when spinal arthritis pain has become persistent and hasn’t responded well enough to anti-inflammatories alone. It works best for the dull, constant aching that characterizes chronic spinal degeneration rather than sharp, acute flares.
Muscle Relaxants for Acute Flares
Spinal arthritis often triggers muscle spasms around the affected joints, which can be as painful as the arthritis itself. Cyclobenzaprine, a common muscle relaxant, can help during these flares. In pooled clinical data, about one in three patients experienced meaningful symptom improvement within 10 days, with the strongest effects showing up in the first four days. The downside is that roughly one in four people experience drowsiness, dry mouth, dizziness, or nausea.
Because the side effects persist while the benefit fades after the first few days, muscle relaxants work best as a short-term rescue option during bad flares rather than something you take every day. One trial also found that adding cyclobenzaprine to naproxen didn’t provide much additional pain relief, so it may not be worth combining the two.
When Nerve Pain Is Part of the Picture
Spinal arthritis can narrow the spaces where nerves exit the spine, causing shooting pain, tingling, or numbness in the arms or legs. Standard painkillers don’t work well on this type of nerve pain. Gabapentin and pregabalin are nerve-specific medications sometimes prescribed off-label in these situations. They were originally designed for seizures and nerve pain after shingles, not for routine arthritis pain, so they’re only worth considering when nerve compression symptoms are clearly present. Common side effects include drowsiness, dizziness, and weight gain.
Biologics for Inflammatory Spinal Arthritis
If your spinal arthritis is inflammatory, specifically a condition called axial spondyloarthritis (which includes ankylosing spondylitis), the medication landscape changes significantly. When NSAIDs alone aren’t controlling the disease, international guidelines recommend starting a biologic, typically either a TNF inhibitor or an IL-17 inhibitor. These are injectable medications that suppress specific parts of the immune system driving the inflammation.
No head-to-head trials have shown one class to be clearly better than the other for spinal symptoms. The choice often comes down to what else is happening in your body. If you have a history of inflammatory eye disease (uveitis) or inflammatory bowel disease, TNF inhibitors are preferred. If significant psoriasis is part of the picture, an IL-17 inhibitor may be the better fit. TNF inhibitors have a longer track record and more real-world safety data, which is why they’re still the most common first choice.
JAK Inhibitors as a Newer Option
JAK inhibitors are oral pills (taken by mouth rather than injected) that became available more recently for inflammatory spinal arthritis. Tofacitinib was approved for ankylosing spondylitis in 2021, and upadacitinib followed in 2022 for both ankylosing spondylitis and its non-radiographic form. The convenience of a pill is appealing, but these drugs carry a boxed warning from the FDA for increased risks of blood clots, major cardiovascular events, certain cancers, and serious infections. Because of these safety concerns, JAK inhibitors are generally reserved for patients who haven’t responded to or can’t tolerate TNF or IL-17 inhibitors.
How Medications Are Typically Combined
Most people with spinal arthritis don’t rely on a single medication. A common pattern for osteoarthritis is using an NSAID during flares, acetaminophen for milder days, and adding duloxetine if pain becomes constant. Physical therapy, exercise, and weight management work alongside any medication plan and can reduce how much medication you need over time.
For inflammatory spinal arthritis, the typical progression starts with NSAIDs, moves to a biologic if the disease stays active, and may add a JAK inhibitor if biologics aren’t effective. Corticosteroid injections into specific spinal joints can provide targeted relief during bad stretches for either type, though they’re not a long-term solution because repeated injections can weaken surrounding tissue.
The “best” medication ultimately depends on whether your arthritis is degenerative or inflammatory, whether nerves are involved, how you tolerate side effects, and what other health conditions you have. Starting with NSAIDs and building from there based on your response is the approach most commonly used, with stronger or more targeted medications added only when simpler options fall short.
