Understanding your AllerVie Health data breach notification letter
If a AllerVie Health letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
AllerVie Health is a healthcare provider specializing in allergy and immunology services, which necessitates the collection and maintenance of highly sensitive patient records. As a healthcare entity, the organization typically stores comprehensive personal data including medical histories, diagnostic information, and insurance details required for clinical care and billing purposes. In 2025, the company officially reported a data security incident to the New Hampshire Attorney General, confirming that unauthorized access to their systems occurred. If you received a data breach notification letter from AllerVie Health, it indicates that your personal or protected health information may have been compromised during this event. This notice is intended to inform you of the incident and provide guidance on the steps you should take to protect your identity and medical privacy.
What to do after the letter
Confirm the notice is genuine
A legitimate AllerVie Health notice references the specific incident reported to the New Hampshire Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
