Alcohol and Meloxicam, a caution.
Alcohol can increase the risk of stomach bleeding while taking meloxicam. Meloxicam is somewhat COX-2 selective but still causes clinically meaningful NSAID GI injury, especially with chronic use. Risk is higher with older age, prior ulcers, high dose, dehydration, or other bleeding-risk drugs.

Caution
What is happening. Alcohol can increase the risk of stomach bleeding while taking meloxicam. Meloxicam is somewhat COX-2 selective but still causes clinically meaningful NSAID GI injury, especially with chronic use. Risk is higher with older age, prior ulcers, high dose, dehydration, or other bleeding-risk drugs.
Mechanism. Meloxicam inhibits prostaglandin synthesis and can impair gastric mucosal defense. Alcohol adds direct mucosal irritation and can worsen NSAID-associated erosive injury and bleeding.
Recommendation. Avoid heavy alcohol while taking meloxicam. If meloxicam is used daily, report black stools, vomiting blood, worsening stomach pain, dizziness, or unusual weakness right away.
