Infant vs. Children's Tylenol: What's the Difference?
For decades, "Infant Tylenol" was a highly concentrated drops formula (80mg/0.8mL), making it 3x stronger than Children's Tylenol. This led to confusion and overdoses.
Good News: Today, in the United States, BOTH Infant and Children's Liquid Tylenol use the exact same concentration: 160mg/5mL.
So why are they sold separately?
- The Bottle Design: Infant bottles are smaller and come with a specific syringe for safe dosing of babies.
- The Price: Infant versions are often priced higher per ounce, despite being the exact same medicine.
Crucial Warning
"Always verify your label. If you have an OLD bottle of concentrated drops (80mg/0.8mL), the math is completely different. Safe practice is to throw it away and buy a new bottle with the standard 160mg/5mL."
Common Questions
Can I give Ibuprofen and Tylenol together?
Yes, they can be alternated every 3 hours (e.g., Tylenol at 12:00, Ibuprofen at 3:00, Tylenol at 6:00). This helps maintain fever control. Always track the times carefully to avoid double dosing the same med.
My baby is under 12 weeks old with a fever. What should I do?
Call your doctor immediately. A fever in a neonate (under 3 months) is a medical emergency and requires professional evaluation, not home treatment.
