Can you take Tylenol (acetaminophen) for a headache?
Yes. Tylenol (acetaminophen) is commonly used to treat headache pain, including tension-type headaches and many types of mild to moderate pain [1].
What dose should you use for headache?
For adults, typical OTC dosing is 650 mg to 1,000 mg per dose, taken every 4 to 6 hours as needed, with a maximum daily total of 3,000 mg (some labels allow 4,000 mg, but 3,000 mg is a safer ceiling for many people) [1].
Follow the label on your specific Tylenol product, because “Tylenol” comes in different strengths and formulations (regular, extra strength, extended release).
When should you avoid Tylenol?
Avoid or ask a clinician first if you have liver disease or drink heavy alcohol, because acetaminophen can cause serious liver injury in high doses [1].
Also be careful about “double dosing.” Many cold, flu, and pain products contain acetaminophen, so you can accidentally exceed the daily limit [1].
What side effects should you watch for?
Most people tolerate Tylenol well when they take it as directed. The main serious risk is liver damage from taking too much acetaminophen [1]. Get urgent medical help if you take more than the label allows or have signs of liver problems (for example, severe nausea/vomiting, right-sided upper belly pain, extreme fatigue, or yellowing of the skin/eyes).
What if Tylenol doesn’t help?
If your headache doesn’t improve after taking acetaminophen as directed, or keeps returning, it may be from a trigger that needs different treatment (like dehydration, lack of sleep, caffeine withdrawal, sinus issues, or medication overuse). Consider switching strategies or speaking with a clinician.
When to seek urgent care for a headache
Get urgent medical attention for a headache that is sudden and severe, after head injury, with weakness/numbness, confusion, fainting, stiff neck with fever, trouble speaking, or vision loss.
