Proper Use

Drug information provided by: Micromedex

Take this medicine after meals or with food (except for enteric-coated capsules or tablets and aspirin suppositories) to lessen stomach irritation.

Take tablet or capsule forms of this medicine with a full glass (8 ounces) of water. Also, do not lie down for about 15 to 30 minutes after swallowing the medicine. This helps to prevent irritation that may lead to trouble in swallowing.

For patients taking aspirin (including buffered aspirin and/or products containing caffeine):

  • Do not use any product that contains aspirin if it has a strong, vinegar-like odor. This odor means the medicine is breaking down. If you have any questions about this, check with your health care professional.
  • If you are to take any medicine that contains aspirin within 7 days after having your tonsils removed, a tooth pulled, or other dental or mouth surgery, be sure to swallow the aspirin whole. Do not chew aspirin during this time.
  • Do not place any medicine that contains aspirin directly on a tooth or gum surface. This may cause a burn.
  • There are several different forms of aspirin or buffered aspirin tablets. If you are using:
    • chewable aspirin tablets, they may be chewed, dissolved in liquid, crushed, or swallowed whole.
    • delayed-release (enteric-coated) aspirin tablets, they must be swallowed whole. Do not crush them or break them up before taking.
    • extended-release (long-acting) aspirin tablets, check with your pharmacist as to how they should be taken. Some may be broken up (but must not be crushed) before swallowing if you cannot swallow them whole. Others should not be broken up and must be swallowed whole.

To use aspirin suppositories:

  • If the suppository is too soft to insert, chill it in the refrigerator for 30 minutes or run cold water over it before removing the foil wrapper.
  • To insert the suppository: First remove the foil wrapper and moisten the suppository with cold water. Lie down on your side and use your finger to push the suppository well up into the rectum.

To take choline and magnesium salicylates (e.g., Trilisate) oral solution:

  • The liquid may be mixed with fruit juice just before taking.
  • Drink a full glass (8 ounces) of water after taking the medicine.

To take enteric-coated sodium salicylate tablets:

  • The tablets must be swallowed whole. Do not crush them or break them up before taking.

Unless otherwise directed by your medical doctor or dentist:

  • Do not take more of this medicine than recommended on the label, to lessen the chance of side effects.
  • Children up to 12 years of age should not take this medicine more than 5 times a day.

When used for arthritis (rheumatism), this medicine must be taken regularly as ordered by your doctor in order for it to help you. Up to 2 to 3 weeks or longer may pass before you feel the full effects of this medicine.
