Do not administer Omnipaque 140 and 350 intrathecally: severe reactions may occur (eg, death, convulsions/seizures, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, rhabdomyolysis, hyperthermia, brain edema). Have emergency treatment and trained personnel readily available. Monitor for hypersensitivity reactions. Cardiovascular disease (monitor). Pheochromocytoma. Homozygous sickle cell disease. Homocystinuria: avoid angiocardiography. Hyperthyroidism. Thyroid dysfunction (esp. children 0–3yrs); monitor. Renal impairment or risk of (eg, diabetes, dehydration, multiple myeloma, CHF, advanced vascular disease). History of severe cutaneous reaction: avoid. Ensure adequate hydration. Avoid extravasation (esp. in arterial or venous disease). Elderly. Pregnancy. Nursing mothers: consider interrupting; pump/discard breast milk for 10hrs after administration.
Omnipaque 240 Pharmacokinetics
Omnipaque 240 Interactions
Concomitant drugs that lower seizure threshold (eg, phenothiazines): not recommended with intrathecal use. Discontinue metformin at time of, or prior to Omnipaque in patients with eGFR 30–60mL/min/1.73m2, history of hepatic impairment, alcoholism, heart failure, or will be given intra-arterial contrast; reevaluate eGFR 48hrs after procedure and restart metformin if renally stable. Increased risk of kidney injury with concomitant nephrotoxic drugs or diuretics. Discontinue CNS active drugs (eg, MAOIs, tricyclics, CNS stimulants, analeptics, tranquilizers, antipsychotics) ≥48hrs before myelography and for ≥24hrs post-procedure. Caution with beta-blockers. May interfere with thyroid uptake of radioactive iodine and decrease efficacy in thyroid carcinoma for up to 6–8 weeks. May reduce iodine-binding capacity of thyroid tissue for up to 2 weeks.
