What are the side effects of aspirin and codeine?

Aspirin and codeine in combination may cause some mild side effects including constipation, dizziness, headache, increased thirst, nausea, rash, sweating, tiredness, or vomiting. Some of the stomach issues may be settled by taking the medication with some food or milk.

 If you have any sign if severe allergic reactions like difficulty breathing, hives, or swelling in the mouth, throat, or face, get medical help right away.

 Some more serious side effects could indicate internal bleeding, possibly triggered by the aspirin: black, bloody, or tarry stools and coughing up blood or vomit that looks like coffee grounds. Additional serious side effects could include the following: convulsions; difficulty urinating; dizziness, confusion, unusual thoughts or behavior; decreased hearing or ringing in the ears; feeling light-headed, fainting; feeling like you might pass out; pale skin, easy bruising or bleeding; ringing in the ears or decreased hearing; severe nausea, vomiting, or stomach pain; shallow breathing, fast or slow heartbeat; swelling, or pain lasting longer than 10 days; wheezing, chest tightness, trouble breathing.
