Privacy Policy


ViroPharma is committed to maintaining the integrity and privacy of your personal information collected through this Web site. This Privacy Policy discloses ViroPharma’s information collection and dissemination practices in connection with the Web site and applies solely to the information that we collect through the Web site. This Privacy Policy does not address personal information that you provide to us in other contexts (eg, through a business or investment relationship not handled through the Web site).


By using the Web site, you signify your acceptance of this Privacy Policy. If you do not agree to the terms of this Privacy Policy, please do not use this Web site. Your continued use of the Web site following the posting of changes to these terms will mean that you accept those changes.


ViroPharma only collects your personally identifiable information ("PII") through this Web site when you choose to provide such information, such as when you provide information on CINRYZE, or participate in the CINRYZESolutions® Patient Resources Program. PII can include your name, date of birth and ZIP code. ViroPharma uses your PII to address your requests for information, products or services. ViroPharma will not sell, rent, license, or trade your PII with third parties for their own direct marketing use unless we receive your express consent to do so. Unless you give us permission to do so, ViroPharma will not share your PII other than as specified in this Privacy Policy.

Disclosures to Third Parties Assisting in Our Operations. ViroPharma may share your PII under confidentiality agreements with other companies that work with, or on behalf of, ViroPharma to provide products and services. These companies, which may include members of ViroPharma’s corporate family, may use your PII to assist ViroPharma in its operations. However, these companies do not have any independent right to share this information.

Disclosures Under Special Circumstances. We may provide information about you to respond to subpoenas, court orders, legal process or governmental regulations, or to establish or exercise our legal rights or defend against legal claims. We believe it is necessary to share information in order to investigate, prevent or take action regarding illegal activities, suspected fraud, situations involving potential threats to the physical safety of any person, or as otherwise required by law.

Business Transfers. We may share your PII with other business entities, in connection with the sale, assignment, merger or other transfer of all or a portion of ViroPharma’s business to such business entity. We will require any such successor business entity to honor the terms of this Privacy Policy.


Each time a visitor comes to the Web site, ViroPharma collects some information to improve the overall quality of the visitor’s online experience.

Aggregated Data. ViroPharma collects aggregate queries for internal reporting and also counts, tracks, and aggregates the visitor's activity into ViroPharma’s analysis of general traffic-flow at the Web site. To these ends, ViroPharma may merge information about you into aggregated group data. In some cases, ViroPharma may remove personal identifiers from PII and maintain it in aggregate form that may later be combined with other information to generate anonymous, aggregated statistical information. Such anonymous, group data may be shared on an aggregated basis with ViroPharma’s affiliates, business partners, service providers and/or vendors; if it does so, ViroPharma will not disclose your individual identity.

CINRYZE® (C1 esterase inhibitor [human]) is an injectable medicine that is used to help prevent swelling and/or painful attacks in teenagers and adults with Hereditary Angioedema (HAE).

Important Risk Information
You should not use CINRYZE if you have had life-threatening immediate hypersensitivity reactions, including anaphylaxis to the product.

Tell your healthcare provider about all of your medical conditions, including if you:

  • have an indwelling catheter/access device in one of your veins.
  • have a history of blood clots, heart disease, or stroke.
  • are taking birth control pills or androgens.
  • are pregnant or planning to become pregnant. It is not known if CINRYZE can harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if CINRYZE passes into your milk and if it can harm your baby.

Tell your healthcare provider and pharmacist about all of the medicines you take, including all prescription and non-prescription medicines such as over-the-counter medicines, supplements, or herbal remedies.

Allergic reactions may occur with CINRYZE. Call your healthcare provider or get emergency support services right away if you have any of the following symptoms:

  • wheezing
  • difficulty breathing
  • chest tightness
  • turning blue (look at lips and gums)
  • fast heartbeat
  • swelling of the face
  • faintness
  • rash
  • hives

Because CINRYZE is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

The most common side effects seen with CINRYZE were headache, nausea, rash, and vomiting. These are not all the possible side effects of CINRYZE. Tell your healthcare provider about any side effect that bothers you or that does not go away. You can also report side effects to ViroPharma Medical Information at (866) 331-5637 or the FDA at 1-800-FDA-1088.

Medicines are sometimes prescribed for purposes other than those listed here. Do not use CINRYZE for a condition for which it is not prescribed. Do not share CINRYZE with other people, even if they have the same symptoms that you have.

Before starting CINRYZE, please read the accompanying Patient Information carefully and each time you get a refill. This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about CINRYZE. If you have questions after reading this, ask your healthcare provider.
