Drug Interaction Report

Vaccination with influenza virus vaccine, H1N1, live is not recommended in children less than 18 years of age who are receiving aspirin therapy. The use of aspirin or related medications has been linked to a serious and potentially fatal condition called Reye's syndrome in children with certain viral infections such as influenza or chicken pox. Because influenza virus vaccine, H1N1, live contains live (but weakened) virus, there is some concern that it can cause Reye's syndrome when used with aspirin. The immunizing doctor should be informed of current or recent therapy with aspirin so that appropriate measures and/or precautions can be taken, such as substituting influenza virus vaccine, H1N1, live with a vaccine that contains inactivated virus. Never give aspirin to children or adolescents who have a fever without talking to a doctor, especially if they also have flu symptoms or chicken pox. It is important to tell the doctor about all other medications being used, including vitamins and herbs. Do not stop using any medications without first talking to the doctor.

Ask your doctor before using aspirin together with ethanol (alcohol). Do not drink alcohol while taking aspirin. Alcohol can increase your risk of stomach bleeding caused by aspirin. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Both pseudoephedrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects.

You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
