Meloxicam: 6 things you should know
Medically reviewed by C. Fookes, BPharm Last updated on Nov 2, 2018.
1. How it works
- Meloxicam helps relieve pain and inflammation by blocking the effects of the enzymes cyclooxygenase (COX)-1 and COX-2. This prevents prostaglandin synthesis (prostaglandins elevate body temperature and make nerve endings more sensitive to pain transmission).
- Meloxicam belongs to a group of medicines known as NSAIDs (nonsteroidal anti-inflammatory drugs).
- Effective for the relief of pain and inflammation associated with osteoarthritis and rheumatoid arthritis.
- NSAIDs (including meloxicam) are considered first-line options for mild-to-moderate arthritis-type pain because at correct dosages they are effective, do not cause dependence, and are readily available at a low cost.
- Generic meloxicam is available.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Stomach-related side effects including indigestion, heartburn, and bleeding. People of an older age, taking other medicines that affect the stomach, or who drink more than 3 glasses of alcohol per day may be more at risk. Meloxicam is considered to have a low potential for stomach-related side effects compared with other NSAIDs.
- Most NSAIDs have been associated with an increased risk of stroke or heart attack. The risk may be higher in patients with preexisting cardiovascular conditions and with higher dosages. NSAID use may cause or worsen high blood pressure or increase the risk of hospitalization for heart failure.
- May not be suitable for some people including those with kidney disease, a history of stomach ulcers or other gastrointestinal disorders, with pre-existing cardiovascular disease, a history of recurrent heart attacks, or following coronary artery bypass graft surgery.
- May increase liver enzymes up to three-fold. Fatal liver injury is rare. Long-term use may also damage the kidneys, and patients should be monitored for signs of worsening renal function. Increases in potassium levels may also be reported.
- May interact with some other medicines such as warfarin, SSRIs, ACE inhibitors, and diuretics.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Can be taken without regard to meals.
- Use the lowest effective dose for the shortest duration of time.
- Available as a suspension.
- Response to different NSAIDs can vary so switching types (such as from meloxicam to naproxen) may improve response.
- NSAIDs should not be used in the last 3 months of pregnancy; always ask your doctor before using any medication during pregnancy.
- Avoid if you have a history of asthma or hives after taking aspirin or other NSAIDs, like ibuprofen.
- Combining with alcohol may increase the risk of stomach ulcer or bleeding.
- Do not use this medicine in the setting of heart bypass surgery (CABG).
- See a doctor immediately if you experience any difficulty with breathing, unexplained sickness or fatigue, loss of appetite, vision changes, fluid retention or abnormal bleeding.
6. Response and Effectiveness
- Peak concentrations are reached within 2 hours (capsule) and 4 to 5 hours (tablets). Meloxicam appears to be recycled in the liver so another peak is reached in 8 hours (capsule) or in 12-14 hours (tablet) after the initial dose.
