Final answer:
Codeine can be given as an alternative if Tylenol #4 is not available.
Step-by-step explanation:
If Tylenol #4 is not available, codeine can be given as an alternative.
Codeine is a medication that belongs to the class of drugs known as opioids. It is commonly used to relieve pain and can be prescribed for mild to moderate pain.
While ibuprofen and aspirin are also pain medications, they do not have the same potency as codeine and may not provide sufficient relief for moderate to severe pain.
