Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions with Alcohol

Pharmacokinetic Interactions

Simultaneous ingestion of NSAIDs, such as ibuprofen (the active ingredient in Advil), and alcohol can affect the absorption, distribution, metabolism, and excretion of both substances. Alcohol can increase the risk of gastrointestinal bleeding and ulceration associated with NSAID use by impairing the protective mucosal lining of the stomach. This effect is particularly pronounced with chronic use and higher doses of NSAIDs.

Pharmacodynamic Interactions

Both NSAIDs and alcohol can affect the central nervous system (CNS). Combining these substances may potentiate CNS depressant effects, leading to increased drowsiness, dizziness, impaired coordination, and slowed reaction time. This combination can significantly impair judgment and motor skills, increasing the risk of accidents.

Hepatotoxicity

Both alcohol and some NSAIDs can exert toxic effects on the liver. While the liver generally processes both substances efficiently, concurrent use, especially with high doses or pre-existing liver conditions, may increase the risk of liver damage. This is often manifest as elevated liver enzymes detected in blood tests.

Gastrointestinal Effects

NSAIDs, particularly at higher doses, can irritate the stomach lining, increasing the risk of ulcers, gastritis, and bleeding. Alcohol exacerbates this effect, leading to a heightened risk of gastrointestinal complications, including nausea, vomiting, and abdominal pain.

Increased Risk of Bleeding

Both alcohol and NSAIDs can inhibit platelet aggregation (the process of platelets clumping together to form blood clots). Combining these substances may prolong bleeding time and increase the risk of bleeding, especially from minor injuries or pre-existing bleeding disorders. This interaction is particularly relevant to patients undergoing surgery or already suffering from conditions involving bleeding.

Management and Recommendations

It is recommended to consult a healthcare professional before concurrently using NSAIDs and alcohol. If unavoidable, minimizing both alcohol consumption and NSAID dosage is crucial. Patients with a history of gastrointestinal problems, liver disease, bleeding disorders, or those on other medications should exercise particular caution.
