Salt Substitutes and Hyperkalemia

Salt substitutes often contain potassium chloride as a replacement for sodium chloride. In older adults, especially those with impaired kidney function or those taking certain medications, using salt substitutes can lead to hyperkalemia (high potassium levels in the blood). This risk is further increased when salt substitutes are used in conjunction with:

• Potassium-sparing diuretics: These medications increase potassium levels in the body.
• ACE inhibitors and ARBs: These drugs, commonly used to treat high blood pressure, can also increase potassium levels.
• Certain antibiotics: Some antibiotics can interfere with potassium excretion.

3. Preventing and Evaluating Medication Nonadherence

Medication nonadherence is a common problem among older adults, often due to factors like:

• Complex medication regimens: Multiple medications with different dosing schedules can be confusing.
• Cognitive impairment: Memory problems or dementia can make it difficult to remember to take medications.
• Physical limitations: Difficulty opening pill bottles or swallowing pills can hinder adherence.
• Cost: Medications can be expensive, and some older adults may skip doses to save money.
• Lack of understanding: Not understanding the purpose of the medication or how to take it can lead to nonadherence.

To prevent and evaluate medication nonadherence in older adults:

• Simplify medication regimens: Work with healthcare providers to consolidate medications and simplify dosing schedules whenever possible.
• Provide clear instructions: Ensure the older adult and their caregiver understand the purpose of each medication, how to take it, and any potential side effects.
• Use memory aids: Suggest using pill organizers, alarms, or medication reminder apps to help remember doses.
• Address physical limitations: Explore alternative medication forms, such as liquids or patches, if swallowing pills is a problem.
• Assess financial barriers: Discuss cost concerns and explore options for medication assistance programs.
• Monitor for side effects: Regularly monitor for side effects and address any concerns promptly.
• Build a support system: Encourage involvement of family members, caregivers, or community resources to provide support and encouragement.
• Regularly review medications: Periodically review all medications with the older adult and their healthcare providers to ensure they are still appropriate and effective.

By taking a proactive approach to medication management, healthcare providers can help older adults stay safe and healthy while maximizing the benefits of their medications.
