Study Notes
- Pediatric drug interactions are important to understand in order to identify common interactions in pediatric patients, recognize the consequences of these interactions, and discuss what to do if an interaction occurs.
Acetaminophen and Anticoagulants
- Warfarin metabolism is inhibited by acetaminophen
- Acetaminophen affects clotting factors
- Taking acetaminophen with an anticoagulant can increase bleeding risk
- To mitigate this interaction, use the lowest effective dose of acetaminophen
- Monitor INR levels more frequently when these drugs are taken together
- Avoid long-term or high-dose acetaminophen use with anticoagulants
- Watch for signs of bleeding
Ibuprofen and Aspirin
- The drug interaction between ibuprofen and aspirin leads to gastrointestinal bleeding and ulcers
- To avoid this drug interaction, avoid concurrent use of ibuprofen and aspirin
- Use alternative pain relievers
Antihistamines and Sedative Medications
- Drug interactions between antihistamines (e.g., diphenhydramine) and sedative medications cause sedation
- Excessive drowsiness can result from this interaction
- Respiratory depression is a possible result of this drug interaction
- Avoid combining antihistamines and sedatives
- Use lower doses if the combination cannot be avoided
- Monitor breathing
- Consider non-sedating antihistamines
Decongestants and ADHD Medications
- The drug interaction between decongestants and ADHD medications can increase heart rate and blood pressure
- Monitor for restlessness, palpitations or high blood pressure
- Consult a doctor before use if the child has heart conditions or is on ADHD medication
Cough Suppressants and Antidepressants
- The drug interaction between cough suppressants and antidepressants can result in a risk of serotonin syndrome
- Avoid this combination if the child is on an antidepressant or mood stabilizer
- Look for non-medicated options in this case
NSAIDs and Antihypertensive Drugs
- Drug interactions between NSAIDs and antihypertensive drugs increase blood pressure
- This combination can cause fluid retention and edema
- This can result in acute kidney injury
- Avoid long-term use of NSAIDs
- Monitor blood pressure and kidney function
- Consider alternative pain relief such as paracetamol (acetaminophen)
- Adjust antihypertensive doses
Corticosteroids and NSAIDs
- The drug interaction between corticosteroids and NSAIDs can lead to gastrointestinal complications
- It increases the risk of fluid retention and hypertension
- It delays wound healing and increases susceptibility to infections
- It has the potential for hyperglycemia
- Use the combination of corticosteroids and NSAIDs with caution
- Prescribe gastroprotective agents (e.g. PPI - Omeprazole)
- Monitor for signs of GI distress
- Limit NSAID use
Warfarin and Antibiotics
- Drug interactions between warfarin and antibiotics inhibits warfarin metabolism
- This combination disrupts gut flora
- Protein binding displacement can occur
- Monitor INR levels closely
- Adjust warfarin dosage if necessary
Methotrexate and NSAIDs
- Drug interactions between methotrexate and NSAIDs means NSAIDs reduce renal clearance of methotrexate
- Increased methotrexate level causes severe toxicity
- Avoid NSAIDs when using high-dose methotrexate
- Monitor for toxicity
- Monitor kidney function and liver enzymes
- Check blood counts (CBC)
- Consider alternative pain relievers
Antibiotics and Oral Antifungals
- The drug interaction between antibiotics and oral antifungals may involve antibiotics altering the balance of normal gut flora
- Fungal growth
- Potential infections
- Avoid combination
- Monitor toxicity symptoms
- Adjust dosages
- Choose alternative antibiotics or antifungals
Digoxin and Diuretics
- Drug interactions between digoxin and diuretics cause electrolyte imbalance
- These can also cause dehydration
- Monitor electrolyte levels
- Check digoxin level
- Use potassium-sparing diuretics (e.g., spironolactone)
- Supplement potassium and magnesium
Iron Supplements and Antibiotics
- Drug interactions: iron binds to antibiotics forming insoluble complexes (Chelation)
- Iron reduces the bioavailability of antibiotics
- Separate doses by at least 2-4 hours to avoid chelation
- Monitor treatment failure
Theophylline and Antibiotics
- Drug interaction: antibiotics inhibit the metabolism of theophylline
- Increased risk of toxicity
Albuterol and Beta-Blockers
- Drug interaction: beta-blockers reduce the effectiveness of albuterol
Albuterol and Diuretics
- Drug interaction: hypokalemia
Ranitidine/Omeprazole and Antifungal
- Drug interaction: reduce absorption of antifungals in the stomach due to reduced acidity
- Administer antifungal at least 2 hours apart from ranitidine or omeprazole
- Use an alternative antifungal
General Precautions
- Avoid multi-symptom medications
- Do not give Aspirin to children because of the risk Reye's syndrome
- Use dosing based on weight, not age alone
- Consult a doctor
