# Match evidence to the exact claim

Evidence means information used to support a claim. Ask whether it concerns the same medicine, the same kind (such as a shot or tablet), and the same health problem.

## A matching source versus a broad claim

### A matching source

The record names the product and the claim it supports. It also makes its limits clear.

### A broad claim

Ask what the source actually says. A medicine name in a study title leaves the treatment question to check.

A study about one medicine or health problem may not answer a question about another. Ask how it supports the medicine and use being offered to you.

## Ask what supports the offer

- Does the source name this exact medicine and the same kind, such as a shot or tablet? 

- Does it address the proposed treatment purpose? 

- Is the source an approval record, board guidance, or a report? 

- What date does the source cover? 

- What does the source leave unanswered? 

## Keep these distinctions

FDA (Food and Drug Administration) guidance checked September 26, 2026 rejects claims that a compounded (made-to-order) product is proven to give the same result as an approved drug. [FDA · Claims about compounded drugs ↗ ](https://www.fda.gov/drugs/human-drug-compounding/fda-telehealth-companies-what-know-when-promoting-compounded-drugs) 

FDA explains that a medicine-problem report by itself cannot show that the medicine was the cause, in material checked September 17, 2026. [FDA · What a report shows ↗ ](https://www.fda.gov/drugs/fda-adverse-event-monitoring-system-aems/fda-adverse-event-monitoring-system-aems-public-dashboard) 

A warning letter records FDA’s accusations when it sent the letter. FDA says later contact with the company may change the status of those issues. A letter is not a final decision, and finding no letter does not prove a company has been checked. [FDA · Letter context ↗ ](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/compliance-actions-and-activities/warning-letters) 

Ask what the letter was about and whether there is a later reply or closing letter. It cannot settle by itself whether your medicine is safe.

## Keep this answer

Ask the person deciding treatment to explain how the source supports your medicine and use, including what is still uncertain.
