Can I give acetaminophen to children under 6 months old?
Yes, acetaminophen (Tylenol) can be given to infants under 6 months old, but only under the guidance of a pediatrician. Because dosing is based on your baby's weight—not age—it's essential to confirm the correct amount with a healthcare provider before administering any medication to young infants.
Key points to know:
- Always consult your pediatrician first before giving acetaminophen to a baby under 6 months.
- Dose by weight, not age for accurate and safe administration.
- Use the dropper or syringe provided with infant acetaminophen to measure precisely.
- Never give ibuprofen to infants under 6 months.
- Seek immediate medical care if your baby has a fever over 100.4°F (38°C), is unusually lethargic, or won't feed.
If your infant is showing symptoms like fever, fussiness, or discomfort, it can be difficult to know whether medication is the right next step—or whether something more serious is going on. Rather than guessing, take 3 minutes to complete a free, instant, online symptom check. It's built by doctors, asks the right questions based on your baby's specific symptoms, and helps you understand possible causes and when to seek care. It's a smart, safe first step before reaching for the medicine cabinet.
