When starting your child on a new medication, parents and caregivers should know potential adverse reactions associated with the medication.
Before learning about adverse reactions, it's important to understand the different types of adverse reactions.
What is an Adverse Reaction?
An adverse drug reaction is a response to a medication which is unintended and potentially harmful.
Adverse reactions can be broken down into 2 categories: “Predictable” or “Unpredictable”.
Predictable | Unpredictable |
|
|
Predictable
Expected due to what we know about the drug.
Usually the most common and least harmful.
Will usually stop when the medication is discontinued.
Side Effects
Drug-Drug Interactions
Drug-Disease Interactions
Drug-Food Interactions
Toxicity
Unpredictable
Not expected from what we know about the drug.
Rare and potentially more harmful.
Allergic
Rash/hives due to a penicillin (antibiotic) allergy
Angioedema (sudden swelling) due to a blood pressure medication such as lisinopril or enalapril.
(please note that is not an exhaustive list - just a list of examples)
Idiosyncratic
Why does it matter?
Risk vs. Benefit
If you know that your child is experiencing a common (non-severe) side effect (ex: tremors & increased heart rate from albuterol), usually the benefits of the medication will outweigh the unwanted effects.
If your child is experiencing effects that are not expected and/or severe, it is time to get in contact with your child’s medical provider or seek additional medical attention. In this case, you should have a discussion with your child’s medical provider about how the benefit might not outweigh the risks.
Bottom Line
Adverse reactions can be split into two general categories: predictable and unpredictable.
Each category is defined by how common the reaction is and severity.
Knowing the differences between each can help determine when you should seek further medical attention.
