Report an Adverse Event, Product Complaint 
or Suspected 
Counterfeit Product

If you experience side effects taking a Lilly medicine, talk to your doctor or other healthcare professional. This includes any possible side effects not listed in the package leaflet. By reporting side effects, you can help provide information on the safety of medicines. See the Yellow Card website or search for MHRA Yellow Card in the Google Play or Apple App Store for how to report 
side effects.
You can also report an adverse event, side effect, product complaint involving a Lilly medicine, or any suspected counterfeit Lilly product directly to Lilly UK using the contact details below.
Medicines with the black triangle symbol (▼) have additional monitoring. This will allow quick identification of new safety information. You can help by reporting any side effects you may get. See the Yellow Card website or search for MHRA Yellow Card in the Google Play or Apple App Store for how to report side effects.
