Ibuprofen Well Pharmaceuticals (Ibuprofen)

Ibuprofen acts systemically to reduce pain, fever and inflammatory processes.

• Mild to moderate pain: provides analgesic relief for headaches, dental pain, musculoskeletal discomfort, and postoperative pain.
• Fever: lowers elevated body temperature by acting on the hypothalamic heat‑regulation centre.
• Arthritic inflammation: diminishes joint swelling and stiffness associated with osteoarthritis and rheumatoid arthritis.

• Ibuprofen non‑selectively inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Reduced prostaglandin synthesis leads to diminished peripheral sensitisation of nociceptors, lower fever set‑point in the hypothalamus, and decreased vascular permeability that underlies inflammation.

Adverse reactions may range from mild to severe and should be monitored during therapy.

Common Side Effects

• Nausea: mild stomach upset that often resolves with food.
• Dyspepsia: discomfort or burning in the upper abdomen.
• Headache: transient tension‑type headache.
• Dizziness: occasional light‑headed sensation.
• Rash: mild skin redness or itching.
• Diarrhoea: loose stools without blood.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration: may present as black stools or abdominal pain.
• Renal impairment: reduced urine output or swelling.
• Severe allergic reactions: hives, swelling of face or throat, difficulty breathing.
• Liver enzyme elevation: abnormal blood tests indicating hepatic stress.
• Cardiovascular thrombotic events: increased risk of heart attack or stroke.
• Blood dyscrasias: rare blood cell abnormalities.

Before initiating ibuprofen therapy, consider the following safety measures.

• Assess renal function: adjust use in patients with impaired kidneys.
• Monitor gastrointestinal risk: use with food or gastro‑protective agents in high‑risk individuals.
• Avoid in known hypersensitivity: discontinue immediately if allergic signs appear.
• Use caution with anticoagulants: heightened bleeding tendency may occur.
• Pregnancy and lactation: consult a healthcare professional before use.
• Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Ibuprofen can interact with several medication classes; awareness helps prevent adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Selective serotonin reuptake inhibitors (SSRIs): heightened hemorrhage potential.
• Lithium: ibuprofen may raise lithium serum concentrations.

Moderate Interactions (Monitor Closely)

• ACE inhibitors: possible reduction in renal function when combined.
• Diuretics: increased risk of renal impairment and electrolyte imbalance.
• Methotrexate: reduced clearance leading to toxicity.
