Adverse reactions and product complaints

Reporting an adverse reaction or product complaint

If you experience an adverse reaction or a product quality issue (e.g., unusual smell or texture, broken tablets, receipt of expired products, etc.), we ask that you report the incident by submitting an adverse reaction or product complaint form. Please discontinue further use of
the original product associated with the complaint.

Depending on the scenario, you may qualify for a refund or replacement for the product associated with the issue.

Information you’ll need to provide

Check if you have the information below ready before filling out a form:

  • Your order number
  • Name of product(s)
  • Lot number
  • Expiration/manufacture date
  • A photo of the issue (optional)
  • Details of the adverse event or quality complaint


The lot number may be found on the label or bottom of the bottle and is usually accompanied by the expiry or manufacture date. If you’re unsure which number to provide, you may write out all of the characters you see or send us a picture of the lot information instead.

Adverse reactions

If you suffer from an adverse reaction from any of your Fullscript purchases, please discontinue the use of the original product immediately. Get in touch with your practitioner to help identify the cause of the reaction then submit an adverse reaction complaint to request a refund.

Product complaints

If you’ve received a product affected by a manufacturer or quality issue, please submit a product complaint to request a replacement or refund, and stop using the product immediately unless instructed otherwise by your practitioner. Our team will follow up with next steps upon review of your complaint.


Product complains should be submitted within 6 months of the original order date.
