Meloxicam is a prescription anti-inflammatory drug used mainly for arthritis pain, and its most common side effects involve the stomach and digestive system. In an 18-month study of 357 rheumatoid arthritis patients taking 15 mg daily, 28% experienced gastrointestinal problems, 18% had skin-related issues, and 15% reported respiratory symptoms. Most people tolerate it well enough to keep taking it, but meloxicam carries serious warnings about heart, gut, and kidney risks that are worth understanding before you start.
Common Side Effects
The side effects most people notice are digestive: nausea, stomach pain, indigestion, diarrhea, and gas. These are the same complaints you’d expect from any anti-inflammatory painkiller, though meloxicam tends to cause fewer stomach problems than older alternatives like ibuprofen or naproxen. A large meta-analysis found that meloxicam users had roughly half the rate of serious stomach complications (perforations, ulcers, and bleeding episodes) compared to people on non-selective anti-inflammatory drugs.
That relative gentleness comes from the way meloxicam works. Your body produces two versions of an enzyme involved in inflammation and tissue protection. One version (COX-1) helps maintain the stomach lining and support kidney function. The other (COX-2) drives pain and swelling. Older painkillers block both equally, which is why they’re hard on the stomach. Meloxicam is moderately selective for the inflammation-driving version, so it disrupts the protective enzyme less. It’s not perfectly selective, though, which is why stomach side effects still happen.
Other common but less frequent effects include headache, dizziness, mild swelling in the hands or feet, and skin rashes. In clinical trials, each of these occurred in a small percentage of patients. Dose doesn’t seem to make a dramatic difference for everyday tolerability. A head-to-head trial comparing 7.5 mg and 15 mg daily found no meaningful difference in how well patients tolerated either dose over three weeks.
Stomach and Intestinal Risks
Beyond everyday discomfort, meloxicam can cause serious gastrointestinal bleeding, ulcers, or even a hole in the stomach or intestinal wall. These events can happen without warning symptoms, sometimes in people who’ve been taking the drug for months without trouble. In the 18-month rheumatoid arthritis study, severe gut complications (perforation, ulcer, or bleeding) occurred in 0.8% of patients, and 3.9% stopped the drug because of stomach-related problems.
Your risk goes up if you’re older, if you’ve had ulcers before, if you take the drug for a long time, or if you combine it with other medications that affect the stomach or blood clotting. Alcohol use also increases the risk.
Heart Attack and Stroke Risk
Meloxicam carries the FDA’s strongest warning label, a boxed warning, for cardiovascular risk. All anti-inflammatory painkillers in this class can increase the chance of heart attack and stroke, and the risk grows the longer you take them. People who already have heart disease or risk factors like high blood pressure, high cholesterol, or diabetes face a greater chance of these events.
Meloxicam should not be used around the time of coronary artery bypass surgery. Blood pressure can also rise during treatment, so monitoring is important, especially when you first start the drug. If you already take blood pressure medication, the anti-inflammatory effect of meloxicam can partially counteract it.
Kidney Effects
Your kidneys rely on the same protective enzyme that meloxicam partially blocks, so the drug can reduce blood flow to the kidneys and impair their function. Long-term use has been linked to kidney damage, including acute kidney failure in some cases. In clinical trials, less than 2% of patients showed signs of kidney stress, such as protein in the urine, elevated waste products in the blood, or blood in the urine.
Certain groups are especially vulnerable. If you’re dehydrated, elderly, have existing kidney problems, or have heart failure, meloxicam poses a higher kidney risk. The combination of meloxicam with common blood pressure drugs (ACE inhibitors or ARBs) can further reduce kidney function, so staying well hydrated matters, and periodic blood work helps catch problems early.
Liver Effects
Liver inflammation can develop during meloxicam use. It’s uncommon, but because it can occur without obvious symptoms, routine blood tests to check liver enzymes are recommended for long-term users. If you notice unusual fatigue, yellowing of the skin or eyes, dark urine, or upper-right abdominal pain, these could signal a liver problem that needs evaluation.
Interactions That Raise Risk
Meloxicam changes how your blood clots by affecting platelet function. Taking it alongside blood thinners, whether antiplatelet drugs like aspirin or anticoagulants like warfarin, significantly increases your bleeding risk, particularly in the digestive tract. Antidepressants in the SSRI class (commonly prescribed for depression and anxiety) also affect platelet function and can compound this effect.
If you take low-dose aspirin for heart protection, adding meloxicam doesn’t just increase bleeding risk. It may also interfere with aspirin’s ability to protect your heart. This is a combination worth discussing carefully with whoever prescribes your medications.
Rare but Severe Skin Reactions
In very rare cases, meloxicam can trigger Stevens-Johnson syndrome or its more severe form, toxic epidermal necrolysis. These are medical emergencies. The early signs often mimic the flu: fever, fatigue, sore throat, and burning eyes. Within one to three days, a painful rash develops that spreads, blisters, and causes the top layer of skin to peel away. The rash can also affect the mouth, eyes, and other mucous membranes. These reactions can occur during treatment or up to two weeks after stopping the drug.
What Long-Term Use Looks Like
Many people take meloxicam for months or years to manage chronic arthritis. In the 18-month study, only 13.7% of patients stopped because of side effects, which means the large majority were able to continue treatment. That said, long-term use requires ongoing attention. Periodic blood work to check kidney function, liver enzymes, and blood counts is standard practice for anyone on the drug indefinitely.
The most important risks, cardiovascular events, serious GI bleeding, and kidney damage, can all develop without early warning signs. This is why routine monitoring matters even when you feel fine. Staying at the lowest effective dose for the shortest time needed remains the general principle for minimizing risk with any drug in this class.
