Using alcohol while taking sulfasalazine can potentially lead to liver injury in people who have liver disease, hypersensitivity, or a drug allergy to the medication. Allergic reactions tend to occur soon after starting the medication, and acute liver failure is possible. Sulfasalazine has, in some cases, been shown to cause liver disease—with or without concurrent use of alcohol.
Mixing Alcohol and Medications
Using alcohol while taking certain medications regularly can be dangerous. Some interactions may be acute, potentially causing an immediate life-threatening reaction and some interactions can lead to gradual health issues.
Azulfidine and Alcohol
There is no specific mention of avoiding alcohol on the FDA label for sulfasalazine.
Heavy alcohol use while taking the medication can have adverse effects on the body, and there are rare reports of liver damage that has been attributed to using sulfasalazine with heavy alcohol use.
In one case report, a 57-year-old man who had a history of alcoholism and had just started taking sulfasalazine was hospitalized with signs of liver injury. When the medication was stopped, his liver functions significantly improved, which suggested that the liver injury was drug-induced and was not solely caused by his prior alcohol misuse.
Liver toxicity from heavy alcohol use while on sulfasalazine can include:
Mild elevation in liver function tests Liver failure Cirrhosis Acute hepatitis
The risk of liver toxicity with alcohol and sulfasalazine is associated with the breakdown of sulfasalazine into sulfapyridine and 5-aminosalicylic acid. Sulfapyridine undergoes a chemical reaction, and is then absorbed in the gut and eliminated. The speed of this process can vary based on a genetic predisposition. People who have a slower process of breaking down and absorbing sulfapyridine can be more predisposed to sulfasalazine-induced liver toxicity.
Liver Toxicity
In rare instances, sulfasalazine can lead to liver toxicity if alcohol is consumed.
Liver injury can be an adverse effect of sulfasalazine. When taking sulfasalazine, it is recommended to have liver function tests on a regular basis to monitor for possible liver damage.
Alcohol can also cause liver injury, and using two substances that can damage the liver may increase the likelihood of this effect.
A Word From Verywell
Moderate consumption of alcohol is generally safe if you are using sulfasalazine. However, it is best to check with your healthcare provider, as you could have additional health issues that may make this combination unsafe for you. Be sure to tell your practitioner and pharmacist about any vitamins, supplements, and herbs that you take—they can also interact with alcohol or with medications such as sulfasalazine.
