From the Guidelines
For a 19-pound infant who is teething, you can give acetaminophen (Tylenol) at a dose of 10 to 15 mg/kg every 6 hours, which translates to approximately 95 mg every 6 hours, and ibuprofen (IBU) at a dose of 10 mg/kg every 8 hours, which is about 95 mg every 8 hours, as needed, not exceeding the maximum daily dose. When calculating the dose, it's essential to consider the child's weight in kilograms, as the dosing recommendations are based on weight 1. To convert the infant's weight from pounds to kilograms, we use the conversion factor: 1 pound is approximately equal to 0.45 kilograms, so a 19-pound infant weighs approximately 8.6 kilograms. Using the recommended dose of 10 to 15 mg/kg for acetaminophen 1, the calculated dose would be 86 to 129 mg every 6 hours, and for ibuprofen, the dose would be 86 mg every 8 hours 1. However, it's crucial to use the infant formulation of these medications and measure with the provided dosing syringe or cup for accuracy to avoid overdosing. Additionally, non-medication relief such as cold teething rings, gentle gum massage, or a clean, cold washcloth for the baby to chew on can be offered. If the infant's symptoms don't improve after 24 hours, or if they develop fever, excessive fussiness, or other concerning symptoms, it's essential to contact the pediatrician promptly. It's also important to note that the maximum daily dose for acetaminophen should not exceed 60 mg/kg 1, and for ibuprofen, the maximum daily dose is not explicitly stated in the provided evidence, but it's generally recommended not to exceed 40 mg/kg per day for infants. Always prioritize the infant's safety and consult with a pediatrician if there are any concerns or questions regarding the dosage or administration of these medications.
From the Research
Teething Relief for 19 lbs Infant
To determine the appropriate dose of Tylenol (acetaminophen) and IBU (ibuprofen) for a 19 lbs infant experiencing teething symptoms, we must consider the available evidence.
- The American Academy of Pediatrics does not recommend topical agents for teething due to concerns of toxicity, as highlighted in a review of lidocaine-based teething gels 2.
- A survey of South Dakota physicians found that 80% recommended acetaminophen or ibuprofen for relieving teething symptoms in infants and young children 3.
- The American Dental Association recommends nonopioid medications, such as ibuprofen and acetaminophen, for managing acute dental pain in children, including toothache and tooth extractions 4.
Dosage Guidelines
While there is no specific dosage information provided in the studies for a 19 lbs infant, the following general guidelines can be considered:
- Acetaminophen (Tylenol) is commonly recommended for infants, but the exact dosage depends on the child's weight and age.
- Ibuprofen (IBU) is also recommended, but its use should be guided by the child's weight and age, as well as the consultation of a healthcare professional.
Important Considerations
It is essential to consult with a healthcare professional before administering any medication to an infant, as they can provide personalized guidance on dosage and treatment options 3, 4. Additionally, the use of topical agents, such as lidocaine-based teething gels, is not recommended due to potential risks and toxicity 2.
