Why does Entresto (sacubitril/valsartan) cause low blood pressure?
Entresto lowers blood pressure by blocking two pathways in the renin-angiotensin system. Valsartan is an angiotensin receptor blocker (ARB), which relaxes blood vessels. Sacubitril increases natriuretic peptides, which also promote vasodilation and help the body remove salt and water. Together, these effects can make blood pressure drop, especially after starting treatment or after dose increases.
Low blood pressure is a known on-target risk with ARBs/RAAS-modifying therapy and is more likely in people who already run low, are dehydrated, or take other blood-pressure-lowering medicines.
What symptoms of low blood pressure should patients watch for?
Patients often notice symptoms such as:
- dizziness or lightheadedness (especially when standing)
- fainting or near-fainting
- unusual weakness or fatigue
- blurred vision
- cold/clammy skin
If low blood pressure symptoms are severe (for example, fainting) or persistent, clinicians typically reassess dosing and contributing factors (dehydration, diuretics, other BP meds).
What should be done if blood pressure runs low on Entresto?
Clinicians usually take a stepwise approach that may include:
- checking whether the person is dehydrated or has low fluid intake
- reviewing other medications that lower blood pressure (diuretics, nitrates, other antihypertensives)
- adjusting the Entresto dose downward or pausing titration
- monitoring blood pressure more frequently, including orthostatic measurements (lying vs standing)
The practical goal is to keep the heart-failure benefits while preventing symptomatic hypotension.
When is low blood pressure more likely with Entresto?
Low blood pressure is more likely if someone has:
- higher diuretic exposure (more volume depletion)
- dehydration or low salt/fluid intake
- kidney impairment affecting fluid balance
- older age
- starting at a higher dose or increasing the dose quickly
- other vasodilators or BP-lowering drugs used at the same time
Is Entresto still safe if you have “low-normal” blood pressure to begin with?
Many people with heart failure tolerate Entresto, but starting and titrating require caution when baseline blood pressure is low or borderline. In practice, clinicians may start at a lower dose, titrate more slowly, and monitor closely for dizziness or orthostatic symptoms.
Could low blood pressure be caused by something else (and not Entresto)?
Yes. Symptoms that feel like “Entresto low blood pressure” can also come from:
- dehydration from vomiting/diarrhea or poor intake
- infection or bleeding
- kidney function changes
- medication interactions
- overdiuresis (too much diuretic effect)
If symptoms are new or getting worse, a clinician will often check hydration status, electrolytes, kidney function, and medication timing.
Does Entresto dosing differ for people who get hypotension?
Often, yes. When hypotension occurs, clinicians may reduce the Entresto dose and slow or stop further titration until symptoms improve. The right target dose is individualized; maintaining tolerability matters as much as reaching a maximum dose.
What are the most urgent “go now” situations?
Seek urgent medical care if low blood pressure comes with:
- fainting
- confusion, inability to stay awake
- chest pain, severe shortness of breath
- signs of shock (very low BP, cool/clammy skin, rapidly worsening symptoms)
