No. While no studies have shown a tolerance build up (or weakening of pain relieving power), over-the-counter pain relievers (including Advil®) should not be used for longer than 10 days unless directed by a physician.
It depends. For most Advil® products you can take 1 capsule/tablet every 4 to 6 hours. For Advil® Migraine take 2 capsules with a glass of water every 24 hours. Click on a product link below to learn more.
Advil® should be used only as directed on the label. Stop taking Advil® and talk to your doctor if your pain gets worse or lasts for more than 10 days, or if your fever gets worse or lasts for more than 3 days.
When used as directed, it is not possible to overdose on Advil®. Signs of overdose are known to occur at 40x the maximum daily dose (1200mg). This low toxicity profile makes Advil® a safe and effective pain reliever for multiple aches and pains.
RX ibuprofen (the active ingredient in Advil®) has a higher dosage than OTC and must be prescribed by a doctor.
