Name: Aspirin, Citric Acid, and Sodium Bicarbonate

What are some things I need to know or do while I take Aspirin, Citric Acid, and Sodium Bicarbonate?

  • Tell all of your health care providers that you take this medicine. This includes your doctors, nurses, pharmacists, and dentists.
  • Do not give to children and teenagers who have or are getting better from flu signs, chickenpox, or other viral infections due to the chance of Reye's syndrome. Reye's syndrome causes very bad problems to the brain and liver.
  • Do not take more than what your doctor told you to take. Taking more than you are told may raise your chance of very bad side effects.
  • Do not take aspirin, citric acid, and sodium bicarbonate for longer than you were told by your doctor.
  • You may bleed more easily. Be careful and avoid injury. Use a soft toothbrush and an electric razor.
  • Talk with your doctor before you drink alcohol.
  • If you smoke, talk with your doctor.
  • If you are on a low-sodium or sodium-free diet, talk with your doctor. Some of these products have sodium.
  • If you have phenylketonuria (PKU), talk with your doctor. Some products have phenylalanine.
  • This medicine may raise the chance of very bad and sometimes deadly stomach or bowel side effects like ulcers or bleeding. The risk is greater in older people. The risk is also greater in people who have had stomach or bowel ulcers or bleeding before. These problems may occur without warning signs. Talk with the doctor.
  • If you are over the age of 60, use this medicine with care. You could have more side effects.
  • This medicine may cause harm to the unborn baby if you take it while you are pregnant. If you are pregnant or you get pregnant while taking aspirin, citric acid, and sodium bicarbonate, call your doctor right away.
  • Tell your doctor if you are breast-feeding. You will need to talk about any risks to your baby.
