How long should you wait before taking more Advil (ibuprofen)?
Advil dosing intervals are typically based on the drug label: take a dose, then wait the recommended number of hours before the next dose. For most adults, that interval is commonly 4 to 6 hours. [1]
What happens if you take it too soon or too much?
Taking ibuprofen doses too close together can raise the risk of side effects and overdose, including stomach irritation/bleeding, kidney problems, and increased cardiovascular risk at higher doses. If you think you took too much or too often, seek medical help right away. [1]
Can you combine Advil with other pain relievers?
Avoid doubling up on other medicines that also contain ibuprofen or other nonsteroidal anti-inflammatory drugs (NSAIDs) (for example, naproxen). Combining NSAIDs increases the chance of stomach bleeding and other complications. [1]
How long until Advil starts working?
Many people feel pain relief within about 30 minutes of taking ibuprofen, though it varies by person and the condition being treated. [1]
When should you not keep dosing and instead get medical advice?
Get medical advice before taking more if you have a history of stomach ulcers or GI bleeding, kidney disease, are on blood thinners, or if you have severe symptoms that aren’t improving as expected. [1]
