Why Report Entresto Side Effects to Your Doctor?
Yes, report any side effects from Entresto (sacubitril/valsartan) to your doctor immediately. This heart failure medication can cause issues like low blood pressure, high potassium levels, kidney problems, cough, dizziness, or angioedema (swelling). Your doctor can adjust the dose, switch treatments, or run tests to address them, preventing worsening health risks.[1][2]
What Side Effects Warrant Urgent Reporting?
Contact your doctor right away for severe symptoms such as:
- Swelling of the face, lips, tongue, or throat (sign of angioedema, which can be life-threatening).
- Fainting, severe dizziness, or rapid heartbeat from low blood pressure.
- Signs of kidney issues like reduced urine output or swelling in legs/ankles.
- Persistent cough, nausea, or fatigue not improving over time.
Milder effects like headache or diarrhea often resolve but still need monitoring.[2][3]
How Does Reporting Help Manage Treatment?
Doctors use reports to track if side effects stem from Entresto interacting with other drugs (e.g., potassium supplements or NSAIDs), improper dosing, or underlying conditions. They might lower your dose from the standard 97/103 mg twice daily or add supportive meds. Regular check-ups include blood tests for potassium and kidney function.[1][4]
Should You Also Report to the FDA?
Yes, alongside telling your doctor, report serious side effects to the FDA via MedWatch (1-800-FDA-1088 or online at fda.gov/medwatch). This helps track rare issues across users and improves drug safety data. Your doctor can file it for you.[3]
What If Side Effects Persist or Worsen?
If symptoms don't improve after reporting, seek emergency care—don't wait. Entresto carries a boxed warning for fetal harm, so inform your doctor if pregnant or planning pregnancy.[2] Switching to alternatives like beta-blockers or ARNI competitors may be needed.
