Liderfeme (Ibuprofen)

Liderfeme (ibuprofen) works by targeting inflammatory pathways that cause discomfort and fever. It is commonly employed for several conditions:

• Pain: provides relief from headaches, dental pain, musculoskeletal aches, and menstrual cramps.
• Fever: lowers elevated body temperature associated with infections or inflammatory states.
• Inflammation: reduces swelling in conditions such as sprains, strains, and minor injuries.
• Arthritis: helps manage pain and stiffness in osteoarthritis and rheumatoid arthritis.

• Ibuprofen inhibits both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, leading to decreased synthesis of prostaglandins that mediate pain, fever, and inflammation. By reducing prostaglandin levels, it diminishes peripheral sensitization of nociceptors and lowers the hypothalamic set‑point for body temperature, providing analgesic, antipyretic, and anti‑inflammatory effects.

Adverse reactions to ibuprofen may vary in frequency and severity.

Common Side Effects

• Stomach upset or dyspepsia.
• Heartburn or acid reflux.
• Nausea or vomiting.
• Dizziness or light‑headedness.
• Headache.
• Mild skin rash.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Severe allergic reactions such as anaphylaxis or angioedema.
• Acute kidney injury or worsening of chronic renal disease.
• Elevated liver enzymes or hepatitis.
• Cardiovascular events including myocardial infarction or stroke.
• Blood dyscrasias such as thrombocytopenia.

When using ibuprofen, consider the following safety measures:

• Assess gastrointestinal risk: avoid use in patients with active ulcers or a history of GI bleeding.
• Use the lowest effective dose for the shortest duration needed.
• Avoid if known hypersensitivity to ibuprofen or other NSAIDs exists.
• Caution in renal or hepatic impairment: monitor function and adjust use accordingly.
• Limit concurrent use with anticoagulants or other NSAIDs to reduce bleeding risk.
• Store at room temperature: keep in the original pack, protect from moisture.

Ibuprofen can affect the activity of several other medicines.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Selective serotonin reuptake inhibitors (SSRIs): heightened gastrointestinal bleeding risk.
• Lithium: ibuprofen may raise lithium serum concentrations.
• ACE inhibitors or ARBs: may reduce renal perfusion, especially in volume‑depleted patients.
• Diuretics: can exacerbate renal function decline.

Moderate Interactions (Monitor Closely)

• Other NSAIDs: additive gastrointestinal toxicity.
• Corticosteroids: increased ulcer risk.
• Methotrexate: reduced clearance leading to toxicity.
• Antihypertensives: possible attenuation of blood pressure‑lowering effect.
• Alcohol: potentiates gastric irritation and bleeding.
