Omniscan (Gadodiamide)

Gadodiamide, the active ingredient in Omniscan, is a gadolinium‑based contrast agent presented as a solution for intravenous use. It enhances magnetic resonance imaging to help visualize vascular structures and tissue characteristics in adult and pediatric patients. GNH USA supplies Omniscan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and diagnostic imaging centres worldwide.

Omniscan is used in magnetic resonance imaging procedures that require contrast enhancement to assess vascular and tissue abnormalities.

- Central nervous system imaging: Improves visualization of lesions, tumors, and inflammatory processes. - Angiography: Enhances delineation of blood vessels for diagnostic and interventional planning. - Body imaging: Improves detection of lesions in liver, kidneys, and other organs. - Cardiac imaging: Assists ​​  ​  ​  ​  ​ ​ ​  ​  ​  ​  ​  enhancement  ​  ​  ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​​ - Whole‑body screening: Provides contrast for comprehensive assessment of multiple organ systems.

Adverse reactions to gadodiamide‑based contrast agents are generally infrequent but can occur.

Common Side Effects: - Nausea: Mild, transient feeling of stomach upset. - Headache: Usually short‑lived and resolves without treatment. - Injection site discomfort: Mild pain or burning sensation at the infusion site. - Warmth or flushing: Temporary sensation of warmth spreading through the body. - Dizziness: Light‑headed feeling that typically subsides quickly.

Serious or Rare Side Effects: - Nephrogenic systemic fibrosis (NSF): Fibrotic skin changes   g   g    g    ewline     ewline   ewline   ewline   ewline

Omniscan should be administered only under conditions where patient monitoring is possible.

- Assess renal function: Check serum creatinine or eGFR before administration. - Review allergy history: Identify prior reactions to contrast media. - Hydration: Encourage adequate fluid intake before and after the procedure. - Use lowest effective dose: Tailor volume to imaging requirements. - Pregnancy and lactation: Use only if clearly needed; weigh benefits against potential risks. - Store at ambient temperature: Keep in original packaging, protect from light and moisture.
