Is it safe to take Cosentyx (secukinumab) with amoxicillin?
There are no known direct drug–drug interactions between Cosentyx (secukinumab) and amoxicillin in the information provided here. Cosentyx is a biologic injection that targets IL-17A, and amoxicillin is a penicillin antibiotic that treats bacterial infections. In general, they are commonly used together when someone develops an infection that needs antibiotics.
What infections would make people take amoxicillin while on Cosentyx?
People on Cosentyx may be treated with antibiotics like amoxicillin for routine bacterial infections (for example, some respiratory or ear infections) based on a clinician’s assessment. Cosentyx can affect immune signaling, so clinicians sometimes take extra care to evaluate infections and decide whether antibiotics are appropriate.
What should you watch for while using both?
If you take amoxicillin while on Cosentyx, the main issues are usually from the antibiotic itself, not a specific interaction with Cosentyx. Watch for:
- Allergic reaction symptoms (rash, hives, swelling, trouble breathing).
- Severe diarrhea or worsening abdominal symptoms.
- Any fever or symptoms that are getting worse instead of better.
If you suspect an allergic reaction or a serious reaction, seek urgent care.
Do you need to stop Cosentyx if you start amoxicillin?
That depends on the reason for antibiotics and how sick you are. For many mild bacterial infections, clinicians may continue treatment. For more significant infections, they may pause biologic dosing until the infection is controlled. Follow the plan from your prescriber rather than stopping on your own.
Who should confirm for your specific case?
Confirm with the clinician/pharmacist who prescribes your Cosentyx or amoxicillin, especially if you have:
- A history of penicillin allergy
- Recurrent infections
- Ongoing or severe infection symptoms
If you tell me the exact amoxicillin dose, why you’re taking it (diagnosis), and when your last Cosentyx dose was due, I can help you think through the usual coordination questions to ask your doctor.
