If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses. These may affect the way your medicine works. Check before stopping or starting any of your medicines.
Elderly patients are more likely to get side effects.
Call your doctor as soon as you can if you get any of these side effects. Let your doctor know if your pain continues, do not take with other pain-killers without advice. Do not treat yourself for a fever with ibuprofen for more than 3 days, or for pain for more than 10 days without asking your doctor for advice. You may be covering up a more serious illness. To reduce unpleasant effects on your throat and stomach, take ibuprofen with a full glass of water and never just before lying down.
