Can I take syrup before bed even if I took Tylenol during the day?

Yes, you can take syrup before going to bed even if you have taken Tylenol during the day. However, it's important to check the ingredients of the syrup to make sure it doesn't contain acetaminophen, which is the active ingredient in Tylenol. If it does contain acetaminophen, you should space out the doses by at least 4 hours and not exceed a total of 4000 mg of acetaminophen in a 24-hour period. Be cautious and mindful of the total amount you are consuming to avoid exceeding the recommended daily dose.
