NSAID

What the letters mean

NSAID stands for non-steroidal anti-inflammatory drug. The “non-steroidal” part matters: it’s specifically naming these as different from corticosteroids (the other big anti-inflammatory family). Both calm inflammation, but they work through different pathways and carry different risks.

The medications this covers

If your physician hands you a prescription or suggests an over-the-counter medication for orthopedic pain, the NSAID list includes:

• Ibuprofen — brand names Motrin, Advil. Over the counter.
• Naproxen — brand names Aleve, Naprosyn. Over the counter.
• Meloxicam — brand name Mobic. Prescription; taken once a day.
• Celecoxib — brand name Celebrex. Prescription; a COX-2 selective NSAID often used when the stomach is a concern.
• Diclofenac — brand name Voltaren. Available as a prescription pill and an over-the-counter topical gel.
• Ketorolac — brand name Toradol. Short-course prescription; stronger, usually limited to five days.
• Aspirin — chemically an NSAID, but generally used for cardiovascular protection rather than orthopedic pain.

Acetaminophen (Tylenol) is not an NSAID. It relieves pain and fever but has little effect on inflammation, and it works through a different mechanism and has a different risk profile. If ibuprofen upsets your stomach, Tylenol is often the first swap.

How they work

NSAIDs block enzymes called COX-1 and COX-2 (cyclooxygenase). Those enzymes produce prostaglandins, the chemical messengers that drive inflammation, pain sensitivity, and fever. With fewer prostaglandins in circulation, swollen tissue calms down, the nerves in the area become less sensitive, and pain drops.

Because the same enzymes also protect the stomach lining and regulate kidney blood flow, the side effects of NSAIDs are predictable: stomach irritation, small increased risk of bleeding, and some effect on kidney function in patients who already have kidney trouble. Taking them with food and at the lowest effective dose addresses most of this.

When NSAIDs are the right call

NSAIDs are most useful when there is an identifiable inflammatory process:

• Early osteoarthritis flares — swelling and stiffness that respond to a short course over 1–2 weeks.
• Acute sprains and strains — taken during the first several days to limit swelling.
• Bursitis — an inflamed fluid sac, often responds well to NSAIDs before anything else is considered.
• Gout flares — classic NSAID territory; they shorten the attack.
• Post-operative pain — an NSAID alongside acetaminophen reduces the need for opioids.
• Tendonitis in its truly inflammatory phase (the first days after a new injury).

When NSAIDs aren’t the answer

There are several orthopedic problems where NSAIDs look reasonable on paper but don’t actually help — and a few where they can get in the way.

• Chronic tendinopathy (long-standing tennis elbow, Achilles, patellar tendon pain) isn’t usually driven by inflammation. The tendon is failing to heal. NSAIDs sometimes mask the pain briefly without moving the tendon toward repair, and may even slow collagen remodeling. Eccentric exercise, PRP, or Tenex tends to work better.
• Fresh fractures. There is reasonable evidence that prolonged NSAID use in the first weeks after a bone fracture slows bone healing. Most surgeons recommend acetaminophen instead during that window.
• Pre-operative week. NSAIDs thin the blood mildly and can increase surgical bleeding. Most protocols have you stop ibuprofen, naproxen, and meloxicam 5–7 days before surgery.
• Patients with kidney disease, heart failure, or active ulcer disease. These groups are generally advised to avoid routine NSAID use. Your physician will guide the alternative.
• Long-term, daily, for years. NSAIDs are designed for flares, not as a lifestyle. If you’re taking one every day for months on end, that’s a signal the underlying problem needs evaluation.

Pill versus gel versus injection

A topical NSAID (diclofenac gel, for instance) delivers the medication directly to the painful joint through skin. Blood levels stay low, so stomach and kidney risk is minimal. This is a first choice for hand and knee arthritis in many patients — particularly older adults on multiple medications.

A corticosteroid injection places a concentrated anti-inflammatory dose directly into the joint or bursa. It’s much more potent than any NSAID by mouth, but it’s also a separate drug class with its own trade-offs.
