Can Cosentyx (secukinumab) cause liver damage?
Cosentyx (secukinumab) has been associated with liver enzyme elevations in some people, which can be a sign of liver irritation or injury. Reports also exist of liver-related adverse events, including cases that required medical evaluation. Because liver injury can have many causes (including other medicines and infections), clinicians typically advise monitoring and stopping or reassessing treatment if liver injury is suspected.
What liver problems are reported with Cosentyx?
The liver-related safety signals reported for Cosentyx include:
- Increases in liver enzymes (for example, ALT/AST), which can show up on routine blood tests.
- Rare reports of more significant liver injury, which may present with symptoms such as jaundice (yellow eyes/skin), dark urine, fatigue, nausea, or right-sided upper abdominal discomfort.
If you develop symptoms consistent with liver injury, seek prompt medical care rather than waiting for a scheduled visit.
Who is at higher risk of liver injury while taking Cosentyx?
Risk is higher when liver stress is already present. Common factors include:
- Pre-existing liver disease (such as hepatitis or cirrhosis)
- Heavy alcohol use
- Concurrent medicines known to affect the liver
- Recent infections, including viral hepatitis
- Treatment combinations where liver effects may overlap
Your clinician may monitor liver labs more closely if you have any baseline liver concerns or take other potentially hepatotoxic drugs.
What should you do if your liver tests change or symptoms appear?
If liver enzymes rise or symptoms suggest liver injury:
- Contact your prescribing clinician promptly.
- They may repeat blood tests (liver enzymes and bilirubin) and evaluate other causes.
- Depending on severity, Cosentyx may be held or discontinued while the cause is assessed.
Do not stop or restart Cosentyx without medical guidance.
How does Cosentyx compare with other biologics for liver safety?
Compared with some other immunotherapies, biologics like Cosentyx are not among the most common causes of severe drug-induced liver injury, but liver enzyme abnormalities can still occur. The key practical point is that any biologic can cause lab changes in susceptible individuals, so clinicians use symptom review and lab monitoring to manage risk.
If you’re asking because you saw a lab result, what does it mean?
If your ALT/AST or bilirubin is elevated, doctors usually interpret it in context:
- Magnitude (mild vs. marked elevation)
- Trend over time (stable vs. rising)
- Presence of symptoms (jaundice, dark urine, abdominal pain)
- Other causes (alcohol, infections, other medications)
Those details determine whether it’s likely related to Cosentyx versus another cause and whether treatment should change.
