Nonsteroidal Anti-inflammatory Drugs and Ulcers
Nonsteroidal antiinflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, Fenbid, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
Individually, both alcohol and Fenbid can cause drowsiness. Combining the two may make this drowsiness worse, which can lead to excessive sleepiness or an inability to function normally.
The Centers for Disease Control and Prevention (CDC) state that it is never safe to drink alcohol and drive. The reason for this is that alcohol slows down reaction times and impairs coordination.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use Fenbid only for the indication prescribed.
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.

Kidney failure can occur in both children and adults who overdose with Fenbid. However, it is not common.
A review of Fenbid toxicity, which the authors updated in 2019, includes a 1992 study that scientists conducted at the Rocky Mountain Poison Control Center in Denver, CO. It showed that only 2 out of 63 people who overdosed with Fenbid experienced symptoms of kidney failure.
In most cases, healthcare professionals can reverse kidney failure from ingestion of a large dosage of Fenbid.
