Introduction
Amidol 370 is known as a contrast agent. It is injected into the body before an X-ray test or CT scan to enhance the visibility of internal body structures like blood vessels and non-bony structures.
Some side effects of this agent include injection site reactions (pain, swelling and redness), nausea and hot flashes. This medicine is given under the supervision of a healthcare professional.
Side effects of Amidol 370

- Injection site reactions (pain, swelling, redness)
- Nausea
- Hot flashes
How to use Amidol 370
Your doctor or nurse will give you this medicine. Kindly do not self administer.
How Amidol 370 works
Amidol 370 is a radiopaque contrast agent. It contains iodine, a substance that absorbs x-rays and makes blood vessels and other non-bony tissues appear more clearly during an X-ray or CT scan.
What if you forget to take Amidol 370?
Not applicable. Amidol 370 is given before imaging test, so it is important to take it at the time as advised by the doctor. If you miss the dose, your test results can be inaccurate.

Mode of Action
Iopamidol is a nonionic iodinated radiographic contrast medium. It allows visualisation of internal body structures by opacifying the path of its flow.
Precaution
May inhibit blood coagulation. Multiple myeloma or other paraproteinaemia. Sickle-cell disease. Known or suspected phaeochromocytoma (monitor closely). Hyperthyroidism. Ensure adequate hydration. History of a previous sensitivity to a contrast medium, sensitivity to iodine, bronchial asthma, hay fever and food allergy. Monitor patients with CHF. Avoid angiography in patients with homocystinuria. Severe arterial or venous disease. Severe renal impairment, combined renal and hepatic disease or anuria, especially when large doses are used. Pregnancy and lactation.
Lactation: Excretion into breast milk unknown; not recommended
