overproduction and buildup of chemicals called porphyrins or porphyrin precursors. AIP is
Patients Diagnosed with AIP Deserve Access to Treatment
For people living with Acute Intermittent Porphyria (AIP), there are treatments available, but many
still encounter barriers to receiving accessible care at their preferred hospitals.
The American Porphyria Foundation (APF) urges all healthcare institutions to provide timely access
to medically necessary care. We encourage everyone involved in the care of patients with AIP to
demand timely access to FDA-approved treatments. We believe:

AIP is a genetic disease and there is no cure. However, there are strategies that can be used to

• Avoiding dieting or fasting, even for short periods
• Avoiding certain medications that can trigger an attack
• Limiting physical and emotional stress
• Avoiding alcohol
People with frequent attacks can also consider wearing a medical alert bracelet.

Prompt Treatment is Critical
Even with proper diet and control of environmental factors, some patients still have recurring, and
often severe attacks. Acute attacks typically require hospitalization and delays in treatment can
be life-threatening and result in serious complications such as irreversible nerve damage.
Treatments can include:
• Medication to manage pain and other symptoms
• Glucose and carbohydrates given orally or intravenously
• Intravenous heme if the patient’s symptoms fail to improve within 36 hours of glucose treatment
