A patient with a history of alcohol abuse, severe gastrointestinal events, liver disease, hypertension or reduced renal function may be more at risk of experiencing side effects while taking Advil, according to Drugs.com. Ibuprofen is a nonsteroidal anti-inflammatory drug and is the active ingredient in Advil. A patient takes this medication to reduce fever, pain or inflammation.
Taking Advil may increase a patient's risk of having a heart attack or stroke if taken in high doses or for a long term, notes Drugs.com. A patient with heart disease is at higher risk of having a heart attack or stroke caused by Advil. Other cardiovascular side effects include peripheral edema and elevated blood pressure, and rare cases of peripheral cyanosis may occur.
The maximum amount of ibuprofen for an adult patient is 800 milligrams per dose, up to four times per day, for a total of 3200 milligrams per day, according to Drugs.com. An overdose may damage the patient's intestines or stomach.
Symptoms of an overdose include bluish lips, disorientation, dizziness, drowsiness and muscle tremors, describes Mayo Clinic. An Advil overdose may also cause hallucinations, mood changes or other mental changes. An overdose can cause the patient to have a slow or irregular heartbeat, fall into a coma or, in severe cases, stop breathing.
