NSAIDs like ibuprofen and naproxen are the best over-the-counter choice for a pulled muscle because they reduce both pain and the inflammation driving it. Acetaminophen (Tylenol) relieves pain equally well, but it won’t address swelling or inflammation at the injury site. Your best pick depends on how long you need relief, what other health conditions you have, and whether you prefer a pill or a topical gel.
NSAIDs vs. Acetaminophen for Muscle Pulls
A review published in the Annals of Internal Medicine found that for acute soft tissue injuries, NSAIDs and acetaminophen produced similar levels of pain reduction. So if pain is your only concern, either option works. The difference is that NSAIDs block the chemical process that causes inflammation, which matters for a pulled muscle where swelling, stiffness, and warmth around the injury are part of the problem. Acetaminophen works in the brain to dull pain signals but does nothing at the site of the strain itself.
For most people with a straightforward muscle pull, an NSAID is the stronger choice. A systematic review and meta-analysis found that NSAID use reduced strength loss, soreness, and markers of muscle damage after acute muscle injury in humans, at least in the short term. The benefit was especially clear for lower-body muscle injuries.
Ibuprofen vs. Naproxen: Choosing Between Them
The practical difference between these two common NSAIDs comes down to how often you need to take them. Ibuprofen (Advil, Motrin) is dosed every 4 to 6 hours, one to two 200 mg tablets at a time, with a daily over-the-counter maximum of 1,200 mg. Naproxen sodium (Aleve) lasts longer: one to two 220 mg tablets every 8 to 12 hours, with a daily cap of 660 mg.
If your pulled muscle is disrupting sleep, naproxen’s longer duration means a dose before bed can carry you through the night. Ibuprofen is better suited for short bursts of activity where you want relief for a few hours and then plan to stop. Neither is dramatically more effective than the other for pain control; the choice is mostly about convenience and your dosing preference.
When Acetaminophen Is the Better Option
NSAIDs aren’t safe for everyone. If you have heart failure, kidney problems, a history of stomach ulcers, or are taking blood pressure medications or diuretics, acetaminophen is the safer path. The cardiovascular risk from NSAIDs is higher in elderly patients and those with pre-existing heart conditions, and the combination of NSAIDs with certain blood pressure drugs can reduce the effectiveness of both while stressing the kidneys.
Acetaminophen’s main risk is liver damage from overdose. The FDA sets the maximum at 4,000 mg per day across all medications you’re taking, which is important because acetaminophen hides in cold medicines, sleep aids, and combination pain products. If you’re using acetaminophen for a muscle pull, check every other medication in your cabinet for it.
Topical Gels: Useful but Limited
Topical NSAID gels (like diclofenac gel, sold as Voltaren) are appealing because they deliver anti-inflammatory medication directly to the area with less absorption into the bloodstream. For a shallow muscle pull close to the skin’s surface, they can provide some relief with fewer stomach and cardiovascular side effects.
However, a randomized, placebo-controlled study comparing topical diclofenac gel to oral ibuprofen for acute musculoskeletal pain found that topical diclofenac was probably less effective than oral ibuprofen. Two days after treatment, the oral ibuprofen group improved more on pain scores than the topical diclofenac group. Adding the gel on top of oral ibuprofen provided no additional benefit. For deeper muscles or more severe strains, oral NSAIDs are the stronger option. Topical gels work best as a supplement for people who can’t tolerate oral NSAIDs or for mild, surface-level strains.
Should You Delay Taking Anti-Inflammatories?
There’s a persistent idea that you should avoid NSAIDs in the first 48 hours after a muscle pull because inflammation is part of the healing process. The evidence in humans doesn’t clearly support this concern. The meta-analysis on NSAID use after acute muscle injury found benefits for pain, soreness, and strength recovery in human subjects in the short term. In animal studies, prolonged NSAID use at later time points appeared to become less helpful and potentially detrimental, but this pattern didn’t show up consistently in human data.
The practical approach: use NSAIDs for the first 3 to 7 days when pain and swelling are worst, then taper off as you start feeling better. There’s no strong reason to tough out the first two days without them, but there’s also no benefit to continuing them for weeks after the acute phase has passed.
Adding a Muscle Relaxant
For more severe pulls, especially in the back, your doctor may prescribe a muscle relaxant alongside an NSAID. A study of over 400 patients with acute low back pain found that the combination of a muscle relaxant with ibuprofen produced significantly greater pain reduction than ibuprofen alone. After seven days, 94% of the combination group reported excellent to good results compared to 77% in the ibuprofen-only group. Both treatments were well tolerated, though the combination carried slightly more side effects like stomach irritation.
Muscle relaxants are prescription-only and cause drowsiness, so they’re typically reserved for pulls severe enough to cause significant spasm or limit daily function. For a mild to moderate strain, an NSAID alone is usually sufficient.
Magnesium for Recovery
Magnesium supplementation won’t replace a pain reliever in the first few days, but it may speed recovery. A systematic review found that magnesium supplementation reduced muscle soreness at 24, 36, and 48 hours after muscle injury, improved feelings of recovery, and showed a protective effect on markers of muscle damage. Magnesium helps muscles clear lactate and maintain glucose levels, both of which support repair.
People who exercise intensely need 10 to 20% more magnesium than sedentary individuals. Low magnesium levels are linked to greater muscle damage and slower recovery. If you’re prone to muscle pulls during training, maintaining adequate magnesium intake through diet or supplements during and between training seasons is a reasonable strategy alongside your short-term pain management plan.
