Arthritis and other causes of joint pain can make everyday activities harder, from walking and climbing stairs to opening jars or getting out of a chair. For many people, anti-inflammatory medicines can help reduce pain, swelling, and stiffness so they can stay more active. This guide explains how these medicines work, who may benefit, important safety considerations, and when to talk with a healthcare professional before starting treatment.
Understanding arthritis and joint pain
Arthritis is not one condition. It is a broad term for problems that cause pain, stiffness, and inflammation in one or more joints. The most common types are osteoarthritis, which is related to wear and tear over time, and rheumatoid arthritis, an autoimmune condition that causes ongoing joint inflammation.
Joint pain can also come from injuries, overuse, gout, bursitis, tendon problems, or other inflammatory conditions. The cause matters because the best treatment depends on whether the pain is mainly from inflammation, mechanical stress, or another medical issue.
Common signs of inflammatory joint problems include swelling, warmth, stiffness in the morning, and pain that worsens after periods of rest. If a joint is very red, hot, severely swollen, or painful after an injury, medical evaluation is important.
- Morning stiffness
- Joint swelling or warmth
- Pain with movement or after rest
- Reduced range of motion
How anti-inflammatory medicines help
Anti-inflammatory medicines can reduce the chemicals in the body that drive pain and swelling. They are often used for arthritis, tendon pain, muscle sprains, back pain, and other conditions where inflammation plays a role.
Two commonly used prescription anti-inflammatory medicines are diclofenac and etoricoxib. Both belong to the NSAID family, though they differ in how selectively they act on COX enzymes. In practical terms, both can help relieve pain and stiffness, but they are not the same medicine and may not be right for every patient.
These medicines may be taken by mouth or, for some forms of diclofenac, applied topically. Topical diclofenac can be useful for localized joint pain such as hand, knee, or ankle discomfort, while oral NSAIDs are often used when more systemic relief is needed. The best option depends on the location and severity of symptoms, your health history, and other medicines you use.
- Reduce inflammation and pain
- May improve stiffness and movement
- Different forms are used for different pain locations
Diclofenac: what patients should know
Diclofenac is a widely used NSAID for relieving pain and inflammation. It is commonly prescribed for arthritis, acute musculoskeletal injuries, menstrual pain, and other painful inflammatory conditions. Depending on the form, it may be used as a tablet, capsule, gel, or patch.
Topical diclofenac is often favored for localized osteoarthritis pain because it delivers medicine directly to the affected area and may have less whole-body exposure than oral forms. Even so, all diclofenac products should be used as directed, since side effects can still occur.
Possible side effects include stomach upset, heartburn, nausea, dizziness, fluid retention, and, in some people, increased risk of stomach bleeding, kidney problems, or cardiovascular events. People with a history of ulcers, kidney disease, heart disease, uncontrolled high blood pressure, or allergies to NSAIDs should discuss diclofenac with a clinician first.
- Available in oral and topical forms
- Useful for joint pain and inflammatory pain
- May increase stomach, kidney, or heart risks in some patients
Etoricoxib: where it fits in treatment
Etoricoxib is a COX-2 selective NSAID used in some countries for arthritis, gout, and other painful inflammatory conditions. By targeting COX-2 more selectively, it may cause less stomach irritation than some traditional NSAIDs for certain patients, though it still carries important risks.
It may be considered when arthritis pain and inflammation are not well controlled with other options or when a clinician wants an NSAID with a different side effect profile. However, COX-2 selectivity does not eliminate risk. Etoricoxib can still affect blood pressure, fluid balance, kidney function, and cardiovascular risk.
Because etoricoxib is not appropriate for everyone, it is especially important to review medical history before use. Patients with prior heart attack, stroke, severe heart failure, active stomach ulcers, or significant kidney or liver disease may need a different treatment plan.
- COX-2 selective NSAID
- May be considered for arthritis and gout
- Still requires careful safety review
Safety tips before taking NSAIDs
Before taking diclofenac, etoricoxib, or any NSAID, it helps to review all current medicines and health conditions with a healthcare professional. This is especially important if you take blood thinners, corticosteroids, aspirin, diuretics, ACE inhibitors, ARBs, lithium, or methotrexate, because interactions can increase risk.
Do not combine multiple NSAIDs at the same time unless a clinician specifically tells you to do so. Taking more than one NSAID does not usually improve pain control, but it can raise the risk of stomach bleeding, kidney injury, and other complications.
People who are pregnant, trying to become pregnant, breastfeeding, older adults, and those with a history of ulcers, high blood pressure, kidney disease, liver disease, asthma triggered by pain relievers, or heart disease should ask for medical advice before using these medicines. Use the lowest effective dose for the shortest time recommended by your clinician.
- Check for medicine interactions
- Avoid taking two NSAIDs together
- Use the lowest effective dose
- Ask a doctor if you have heart, kidney, or ulcer history
Beyond medicine: other ways to manage arthritis pain
Anti-inflammatory medicine is only one part of arthritis care. Many patients also benefit from movement, physical therapy, weight management, heat or cold therapy, supportive footwear, braces, and joint-friendly exercise such as walking, swimming, or cycling.
For osteoarthritis, reducing extra joint load can make a noticeable difference, especially for the knees, hips, and spine. For inflammatory arthritis, early medical treatment may help prevent joint damage, so ongoing care with a clinician is important rather than relying only on pain relief.
You should seek medical evaluation if joint pain lasts more than a few weeks, keeps returning, or is paired with fever, unexplained weight loss, rash, severe swelling, or sudden inability to bear weight. Early diagnosis can help guide treatment and protect joint function.
- Physical activity can support joint health
- Weight management may reduce pressure on joints
- Persistent or severe symptoms need medical review

Common questions
Can diclofenac help arthritis pain?
Yes, diclofenac is commonly used to treat arthritis-related pain and inflammation. It may be helpful for osteoarthritis and other painful inflammatory conditions, but the right form and dose depend on your health history and the joint involved.
Is etoricoxib safer than other NSAIDs?
Not necessarily. Etoricoxib may cause less stomach irritation for some patients, but it can still raise risks related to blood pressure, fluid retention, kidney function, and the heart. A clinician should decide whether it is a good choice for you.
Can I take ibuprofen with diclofenac or etoricoxib?
Usually no, unless a healthcare professional specifically tells you to. Taking more than one NSAID together can increase the risk of stomach bleeding and kidney problems without giving much extra pain relief.
When should I see a doctor for joint pain?
See a doctor if pain is severe, lasts more than a few weeks, or comes with swelling, redness, warmth, fever, or trouble using the joint. Prompt evaluation is especially important after an injury or if the pain is affecting daily activities.
