Pros and cons of Amiloride
Pros
- Helps prevent low potassium levels in people taking certain diuretics (water-pills)

Cons
- Not a first-choice option for treating high blood pressure if used alone
- Need regular blood tests to check potassium levels

Pharmacist tips for Amiloride
- Take amiloride with food at the same time every day.
- Dizziness is a common side effect of amiloride. It should go away as your body gets used to the medication. If it becomes bothersome or worsens, speak to your prescriber.
- Check your blood pressure at home and keep a log of the readings. Bring it to your appointments so your prescriber can see how well amiloride is working and decide if any changes are needed.
- Try to eat a balanced diet that's low in salt while you're taking amiloride. This can help lower your blood pressure and reduce fluid buildup. Ask your care team for meal planning resources or other ways to manage your blood pressure safely.
- Since amiloride raises your potassium levels, avoid taking potassium supplements and using potassium-containing salt substitutes. Speak to your prescriber about the safest amount of potassium-rich foods for you.
- Contact your prescriber right away if you're pregnant or thinking of getting pregnant while you're taking amiloride. Since there are other recommended blood pressure medications during pregnancy, your prescriber will probably consider a different medication for you.
Risks and warnings for Amiloride
Amiloride can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
High potassium levels
- Risk factors: Kidney problems | Conditions that affect kidney function | Diabetes | Taking other medications that raise potassium levels | Using potassium-based salt substitutes | Older adults
Amiloride can raise the amount of potassium in your blood, which can sometimes be dangerous. Your risk is greater if you have diabetes, kidney problems, or if you're taking other medications that also raise potassium levels. For this reason, make sure your prescriber knows your full medical history and the medications you're taking before you start treatment. You'll also want to avoid using potassium-based salt substitutes in your food. Tell a healthcare professional right away if you have signs of high potassium levels, such as nausea, muscle weakness, irregular heartbeat, or a numbing or tingling feeling.
