Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation. While most people tolerate it well, it can cause side effects in some individuals. Here are some of the worst side effects of meloxicam:

• Bleeding: Meloxicam may cause bleeding in the stomach or bowels, which can be fatal. This problem can happen without warning signs, and it is more likely to occur if you or your child have had a stomach ulcer in the past, if you smoke or drink alcohol regularly, if you are over 60 years of age, are in poor health, or are using certain other medicines (eg, steroids, blood thinner).

• Allergic reaction: Meloxicam may cause a serious type of allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, or fainting.

• Liver damage: Meloxicam may affect your liver, causing symptoms such as yellowing of your skin or whites of your eyes and liver inflammation, damage, or failure. Your doctor may check your liver function while you take this drug.

• Multiorgan hypersensitivity/DRESS: This is a rare but serious side effect of meloxicam that can cause fever, rash, and organ failure. If you experience any of these symptoms, you should seek medical attention immediately.

• Organ failure or serious heart problems: Overdosing on meloxicam can cause organ failure or serious heart problems. If you think you’ve taken too much of this drug, call your doctor or seek guidance from the American Association of Poison Control.

It is important to note that these side effects are not common, and most people who take meloxicam do not experience them. However, if you experience any of these symptoms, you should seek medical attention immediately. Other side effects of meloxicam may include stomach upset, diarrhea, and swelling.
