Drug Incompatibility in Paediatrics
In infusion therapy, drug incompatibility is a well-known challenge. In paediatrics and neonatology, this is no exception. This makes it even more important to know which risk factors you should be aware of, and which measures you can take to protect your young patients from harmful drug interactions.

Drug incompatibility is the undesirable reaction between a drug and a solution, container or another drug. There are either physical or chemical types of incompatibilities associated with intravenous administration.1, 2
Paediatric and neonatal patients in hospitals are often affected by polypharmacy. The concurrent use of multiple medications poses a significant risk of adverse drug events (ADEs) also connected to drug–drug incompatibility.7
Major drug–drug interactions can be life-threatening. At one children's hospital, older patients or patients with longer hospital stays or with complex chronic conditions (CCC) were more likely to be exposed to that risk. In the 10-year-old to 20-year-old age group, potential drug–drug interactions (PDDI) occurred in more than half of the patients.7
“Exposure to major potential drug-drug interactions occurs in 41% of pediatric hospitations in childrens hospitals.”
The number of drugs prescribed could be identified as a risk factor for potential intravenous drug incompatibility. In addition, pH level is the major factor for drug incompatibility. Drugs with an extreme pH, such as phenobarbital and phenytoin, are more likely to contribute to the risk.8
In day-to-day operations at the paediatric or neonatal ICU, separate drug administration is often not possible due to the large number of intravenous drugs used and limited venous access.6
Furthermore, high off-label use in paediatrics and neonatology compared to adult patients is an associated risk, resulting in only a limited number of drugs being approved for children.8
Drug incompatibility can have serious health consequences for patients in paediatrics and neonatology. In addition, the financial aspect for paediatric and neonatal wards and hospitals is not to be underestimated due to prolonged hospitalisations. To prevent the risk of drug interactions, we want to raise awareness of the possible adverse reactions beforehand.
Potential drug interactions may lead to:
Depending on the various treatment processes and individual risk factors for potential incompatibilities, there are a number of preventive solutions.
In general, the following strategies should be considered to increase safety with regard to drug incompatibilities, especially in intravenous therapy.
