Melox (Meloxicam)

• Melox (meloxicam) is an NSAID that reduces inflammation by inhibiting COX‑2, and it is indicated for the following conditions:
• Osteoarthritis: decreases joint pain, stiffness and swelling, improving functional ability in patients with degenerative joint disease.
• Rheumatoid arthritis: lessens inflammatory joint pain, reduces swelling and may improve range of motion in chronic autoimmune arthritis.
• Acute pain and inflammation: offers prompt relief of moderate to severe pain and inflammation from musculoskeletal injuries or postoperative states.

• Meloxicam selectively inhibits the cyclooxygenase‑2 (COX‑2) enzyme, which blocks the conversion of arachidonic acid to prostaglandins responsible for pain, fever and inflammation. By sparing COX‑1, it preserves gastric mucosal protection while providing anti‑inflammatory and analgesic effects. The inhibition is dose‑dependent and results in decreased synthesis of inflammatory mediators in synovial tissue, cartilage and peripheral nerves, leading to reduced edema and sensitization of nociceptors.

Melox may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, abdominal pain or mild heartburn that may occur shortly after injection.
• Headache: mild to moderate throbbing headache, often transient and responsive to simple analgesics.
• Dizziness or vertigo: transient sensations of light‑headedness or imbalance, usually resolving without intervention.
• Injection site reactions: erythema, swelling, warmth or mild pain at the intramuscular administration site.

Serious or Rare Side Effects

• Severe gastrointestinal ulceration or bleeding: may present with melena, hematemesis or severe abdominal pain requiring medical attention.
• Cardiovascular events: increased risk of myocardial infarction, stroke or unstable angina, particularly in patients with existing heart disease.
• Renal impairment: acute kidney injury, reduced urine output or worsening of chronic renal insufficiency, necessitating monitoring of renal function.

When prescribing Melox, clinicians should consider several precautionary measures to minimize risks.

• Assess renal function: evaluate baseline creatinine clearance before initiating therapy.
• Monitor gastrointestinal risk: avoid use in patients with active ulcers or a history of GI bleeding.
• Cardiovascular assessment: use cautiously in individuals with known heart disease or hypertension.
• Concomitant NSAIDs or anticoagulants: avoid or closely monitor for additive bleeding risk.
• Pregnancy and lactation: contraindicated or use only if benefits outweigh potential risks, as safety data are limited.
• Store at ambient temperature: keep below 25°C, protect from moisture and light, and retain in original packaging.

Melox can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Other NSAIDs or COX‑2 inhibitors: additive gastrointestinal toxicity.
• High‑dose aspirin: heightened bleeding tendency and renal effects.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal function when combined.
• Diuretics: potential for decreased potassium and renal impairment.
• Lithium: NSAIDs can raise lithium serum levels, risking toxicity.
