Pedmarqsi contains sodium

3. How Pedmarqsi is given

Before you or your child will receive this medicine, he/she will be given anti-sickness medicines to help prevent vomiting.

This medicine is a solution that is given as an infusion (drip) into a vein by a doctor or nurse. This is usually done via a tube inserted into a vein in the chest, known as a central line. The infusion is given over 15 minutes. Treatment is started 6 hours after the dose of cisplatin has finished.

The dose of this medicine is worked out based on your size (body surface area) in m2 , which is calculated from height and weight. The recommended dose for those weighing 10 kg or more is 12.8 g per m2 ; lower doses are given to those weighing less than 10 kg. Your doctor will work out the dose that is right for you or your child.

If you or your child receives more Pedmarqsi than he/she should

Because the dose is worked out and checked by healthcare professionals, it is unlikely that you or your child will be given the wrong amount. In case of overdose, you or your child may experience nausea, vomiting, changes to levels of sodium, phosphate or potassium in the blood, changes to blood pressure, or acidic blood (metabolic acidosis) which can cause nausea, vomiting, drowsiness and breathlessness.
