Is it safe to consume alcohol during cosentyx treatment?

Does alcohol interact with Cosentyx?
Cosentyx (secukinumab) is a monoclonal antibody that targets interleukin-17A. Alcohol does not directly bind to the drug or change how it works, but both alcohol and Cosentyx can stress the liver and immune system, so combined use is not automatically harmless.

How does the liver handle both substances?
Cosentyx is cleared through protein breakdown rather than liver enzymes, so it does not compete with alcohol for metabolism. However, heavy drinking can still raise liver enzymes and inflammation, which may complicate long-term safety monitoring while a patient is on the drug.

What do prescribing information and patient reports say?
The official Cosentyx label lists no specific alcohol contraindication. Clinical trials excluded patients with active alcohol-use disorder, so real-world data on moderate versus heavy drinking are limited. Some patients report increased fatigue or skin irritation after drinking, but these effects are anecdotal and not proven to be caused by the combination.

Are there other health risks to consider?
Cosentyx raises the chance of infections, and alcohol can suppress immune responses and irritate mucous membranes, potentially adding to that risk. Patients with psoriatic arthritis or ankylosing spondylitis who already take other medications (methotrexate, NSAIDs) face extra liver strain when alcohol is added.

When should patients talk to their doctor about drinking?
Anyone on Cosentyx who drinks regularly should ask their rheumatologist or dermatologist for personalized advice. Blood tests that track liver function and infection markers are usually done every few months; results can help decide whether occasional moderate drinking is acceptable or whether complete avoidance is safer.
