Don’t miss what’s next in HAE

Is HAE management forcing you to make trade-offs?

Living with HAE can be complicated and frustrating.
Knowing how and when to take your medication shouldn’t be.

TRADE-OFFS WITH HAE INJECTIONS

FEAR OF NEEDLES

Needles may cause anxiety

TRAVEL PLANNING

Injections can be difficult to carry, require more planning, and take up space

FAMILY PLANNING

Treatment options should consider impact on personal choices in family planning

SIDE EFFECTS

May cause pain and/or a reaction at the injection site

REQUIRES TRAINING

Learning to give oneself an injection can take time and require training

TIRED OF NEEDLES

Some people may get tired of giving themselves injections and may avoid treatments as a result

TRADE-OFFS WITH HAE ORALS

EFFECTIVENESS

On average, currently available orals may not provide injection-like efficacy

SIDE EFFECTS

For prevention of attacks, currently available orals may have side effects that could lead people to stop therapy

TRADE-OFFS WITH HAE INFUSIONS

TIME CONSUMING

May require travel to an infusion center

HARD TO SELF-ADMINISTER

May be hard to find a vein or get IV to work

CONFLICTS WITH PLANS

May interfere with personal and work plans

SIDE EFFECTS

May cause headaches, nausea, rash, and fever

NEED ASSISTANCE

May need other people for help giving IV

TRAVEL ISSUES

When away from home, hard to give oneself an IV

While current HAE management may help, are you making trade-offs among effectiveness, side effects, and convenience?

While effectiveness is important in HAE management, people also prioritize few side effects and convenience

People want few side effects AND an effective management that fits into their lives

Convenience is important, but people with HAE also value effectiveness and/or few side effects

How can something so effective also be so hard for some people to take and carry around?

What good is a treatment that fits your life if you may not be able to trust it?

Should you have to schedule your whole life around your HAE?

GET THE FACTS

There are two ways to manage HAE

  • Prevent attacks
  • Treat attacks if they occur

Attacks may be triggered by injury, stress, or even excitement—but may also appear for unknown reasons

Because HAE is rare and healthcare providers may not easily recognize it, attacks are often mistaken and mistreated as allergic reactions or appendicitis

The usual treatments healthcare providers give for allergies will not work for HAE

  • Allergy medicines, corticosteroids, and epinephrine (adrenaline) do not work for HAE attacks
