Indosin

Indometacin, the active ingredient in Indosin, is a nonsteroidal anti-inflammatory drug (NSAID) presented as a gel for cutaneous use. It works by decreasing prostaglandin production and is employed to relieve pain and inflammation in rheumatoid arthritis, osteoarthritis, gout and other musculoskeletal disorders.

GNH USA supplies Indosin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Indometacin is used in the management of inflammatory and painful conditions affecting the musculoskeletal system. - Rheumatoid arthritis: reduces joint pain, swelling and stiffness. - Osteoarthritis: alleviates chronic joint discomfort and improves mobility. - Gout: diminishes acute gouty attacks and associated inflammation. - General musculoskeletal pain: provides topical relief of localized pain and inflammation.

Topical indometacin may cause local and systemic adverse reactions.

Common Side Effects: - Skin irritation: redness or discomfort at the application site. - Burning sensation: transient warmth or stinging after use. - Itching: mild pruritus localized to the treated area. - Dry skin: occasional flaking or dryness where the gel is applied. - Headache: occasional mild headache unrelated to the disease.

Serious or Rare Side Effects: - Severe allergic reaction: rash, swelling, or difficulty breathing. - Stevens‑Johnson syndrome: rare but serious skin disorder. - Gastrointestinal ulceration: possible systemic absorption leading to ulcer risk. - Liver toxicity: elevated liver enzymes in rare cases. - Kidney impairment: reduced renal function with extensive use. - Blood dyscrasias: rare blood count abnormalities.

When using Indosin, consider the following precautions to minimize risk. - Assess renal function: monitor kidney parameters in patients with existing renal impairment. - Avoid use in active peptic ulcer disease: increased risk of gastrointestinal complications. - Limit exposure to sunlight: the gel may increase photosensitivity on treated skin. - Do not apply to broken or infected skin: risk of enhanced systemic absorption. - Store at room temperature: keep in the original container, protect from moisture and heat.

Indometacin can interact with several medicines; interactions are grouped by clinical significance.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): increased bleeding risk. - Lithium: elevated lithium serum concentrations. - Methotrexate: enhanced methotrexate toxicity. - ACE inhibitors or ARBs: potential reduction in renal function. - Selective serotonin reuptake inhibitors: heightened bleeding tendency.

Moderate Interactions (Monitor Closely): - Diuretics: possible additive renal impairment. - Corticosteroids: increased gastrointestinal ulcer risk. - Other NSAIDs: additive toxicity and gastrointestinal side effects.
