Important information about Aspirin

Several factors need to be taken into account in determining the right aspirin dosage that someone needs: body weight, other diseases or the use of other medicines. If your doctor has prescribed a different aspirin dosage that the ones mentioned here, don’t change that and always follow his indications. If you miss your dose you need to take it as soon as you remember, or if it’s time for your next dose, don’t worry about the missed one and continue with your regular schedule. Never use a double dose to replace the missed one. If you have questions about what to do after missing your aspirin dosage, ask your doctor for more information. Also, keep in mind that some people can experience Aspirin side effects or Aspirin allergy.

In case of prolonged treatment with this drug, it is best to choose enteric-coated aspirin tablets, because they are coated with special substances that prevents irritations of the stomach. This special coating allows a tablet to resist the action of gastric secretions, and not dissolve before reaching the small intestine. Since this coating delays the effect of the drug, the use of enteric-coated tablets is not indicated when you want a quick relief. You can take your aspirin dosage with food to avoid stomach upset. Enteric-coated aspirin can be taken without food.

Never miss your daily aspirin dosage if you want to treat the pain or condition you’re suffering from. Aspirin can be administrated orally, or can be chewed for faster effects (installs in about 15 minutes).
