MST side effects

Get emergency medical help if you have signs of an allergic reaction: sneezing, runny or stuffy nose; wheezing or trouble breathing; hives; swelling of your face, lips, tongue, or throat.

MST may cause serious side effects. Stop using MST and call your doctor at once if you have:

  • new symptoms such as redness or swelling;
  • ringing in your ears, hearing loss;
  • a light-headed feeling, like you might pass out;
  • new or worsening stomach pain; or
  • bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds.

    • Less serious side effects may be more likely, and you may have none at all.

    This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

    Before taking MST

    MST can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. Do not use MST just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

    MST may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using this medicine, especially in older adults.

    You should not use this medicine if you are allergic to aspirin or other salicylates.

    Ask a doctor before giving the medicine to a child younger than 12 years old. Do not give this medicine to a child or teenager with a fever, flu symptoms, or chickenpox. Salicylates can cause Reye's syndrome, a serious and sometimes fatal condition in children.

    Ask a doctor or pharmacist if this medicine is safe to use if you have ever had:

  • bleeding problems;
  • heartburn, stomach ulcer, or stomach bleeding;
  • asthma;
  • heart disease, high blood pressure;
  • liver disease, cirrhosis, or if you drink more than 3 alcoholic beverages per day;
  • kidney disease;
  • arthritis, gout; or
  • diabetes.

    • Ask a doctor before using this medicine if you are pregnant or breastfeeding.

    If you are pregnant, you should not take this medicine unless your doctor tells you to. Taking an NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.
