Administration Instructions for Patiromer

Patiromer should be taken with food. Mix the powder with water and drink it immediately. Do not take patiromer within 3 hours of other oral medications, as it can interfere with their absorption. Always follow your doctor’s instructions on how to take this medication.

Patiromer Side Effects and Adverse Reactions

Like all medications, patiromer can cause side effects. Some are more common than others, and it’s important to talk to your doctor if you experience any of the following:

1. Constipation (Common): Some patients may experience difficulty with bowel movements.
2. Diarrhea (Less Common): Loose or watery stools may occur in some patients.
3. Nausea (Common): Feeling nauseous is a possible side effect.
4. Low Magnesium Levels (Hypomagnesemia) (Less Common): Patiromer can lower magnesium levels in the blood, which may cause muscle cramps or weakness.
5. Abdominal Discomfort (Common): Some patients report mild stomach pain or bloating.

Contraindications for Patiromer

A contraindication is a specific situation or condition where a medication should not be used because it may be harmful. If you have any of the following conditions, you should not take patiromer. Always consult with your healthcare provider before starting or stopping any medication. If you have concerns, you can schedule a telemedicine appointment with one of our providers.

1. Severe Hypokalemia (Low Potassium Levels): Patiromer is used to lower potassium levels, so if your potassium is already too low, taking this medication can worsen the condition, leading to muscle weakness, irregular heartbeats, or even life-threatening complications.
2. Severe Constipation or Bowel Obstruction: Patiromer can cause or worsen constipation. If you already have severe constipation or a bowel obstruction, taking this medication could lead to further complications, including a complete blockage of the intestines.
3. Allergy to Patiromer or its Ingredients: If you have had an allergic reaction to patiromer or any of its components, you should not take this medication. Allergic reactions can range from mild rashes to severe, life-threatening conditions like anaphylaxis.

Drug to Drug Interactions

Patiromer can interact with other medications, which may affect how well it works or increase the risk of side effects. Be sure to inform your healthcare provider about all the medications you are taking, including prescription drugs, over-the-counter medications, and supplements. Here are some common medications that may interact with patiromer:

1. Levothyroxine (Synthroid): Patiromer can reduce the absorption of levothyroxine, a medication used to treat thyroid disorders. This may make your thyroid condition harder to manage.
2. Metformin (Glucophage): Patiromer may decrease the absorption of metformin, which is used to manage blood sugar levels in people with diabetes. This could result in less effective blood sugar control.
3. Ciprofloxacin (Cipro): Patiromer can interfere with the absorption of ciprofloxacin, an antibiotic, making it less effective in treating infections.
4. Loop Diuretics (e.g., Furosemide/Lasix): These medications are often used to treat heart failure or kidney disease. Combining them with patiromer may increase the risk of low potassium levels (hypokalemia).

Patiromer in Pregnancy

Is it safe to take Patiromer when pregnant?

There is limited information on the use of Patiromer during pregnancy. While animal studies have not shown harm to the fetus, no well-controlled studies have been conducted in pregnant women. Since Patiromer is not absorbed into the bloodstream, it is generally considered to pose a low risk to the developing baby. However, it is essential to consult your healthcare provider before taking any medication during pregnancy. If you are pregnant or planning to become pregnant, consider scheduling a telemedicine visit with one of our providers to discuss your treatment options.

Patiromer while Breastfeeding

Is it safe to take Patiromer while breastfeeding?

Because Patiromer is not absorbed into the bloodstream, it is unlikely to pass into breast milk. However, there is no clinical data available on its safety during breastfeeding. If you are breastfeeding or planning to breastfeed, it is important to discuss this with your healthcare provider to carefully weigh the potential risks and benefits. You can book a telemedicine appointment with one of our providers for personalized advice.

Estimated Cost of Patiromer Medication

The estimated cost of a 30-day supply of Patiromer (brand name Veltassa) without insurance ranges from approximately $600 to $700. However, with a GoodRX coupon, you may be able to reduce the cost to around $500. Prices can vary depending on the pharmacy and location, so it’s a good idea to check for the best available discounts.

Possible Alternatives to Patiromer

If you have been diagnosed with any of the following conditions, alternative treatments or lifestyle changes may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. If you need guidance, our telemedicine providers are available to assist you.

1. Hyperkalemia: In addition to Patiromer, medications such as sodium polystyrene sulfonate (Kayexalate) or sodium zirconium cyclosilicate (Lokelma) may help lower potassium levels. Dietary adjustments, such as reducing the intake of potassium-rich foods (e.g., bananas, potatoes), can also be beneficial.
2. Chronic Kidney Disease: Managing blood pressure, blood sugar, and cholesterol levels is crucial to slowing the progression of kidney disease. Medications like ACE inhibitors or ARBs are commonly prescribed. Dietary changes, such as reducing sodium and protein intake, may also be helpful.
3. Heart Failure: Along with medications like beta-blockers, ACE inhibitors, and diuretics, lifestyle changes such as reducing salt intake, maintaining a healthy weight, and engaging in regular exercise can improve heart function.
4. Diabetes: Managing blood sugar levels through medications like insulin or metformin, along with lifestyle changes such as a balanced diet and regular physical activity, is essential for controlling diabetes.
5. Hypertension: Medications like ACE inhibitors, ARBs, and calcium channel blockers, combined with lifestyle changes such as reducing sodium intake, losing weight, and exercising regularly, can help manage high blood pressure.
6. Acute Kidney Injury: Treatment focuses on addressing the underlying cause, such as dehydration or infection. In some cases, temporary dialysis may be necessary. Avoiding medications that can harm the kidneys, such as NSAIDs, is also important.
7. End-Stage Renal Disease: Dialysis or kidney transplantation is often required. Managing symptoms and complications through medications and dietary changes is also essential.
8. Chronic Heart Failure: Similar to heart failure, treatment involves medications like beta-blockers and diuretics, along with lifestyle changes such as reducing sodium intake and exercising regularly.
9. Metabolic Acidosis: This condition is often treated with sodium bicarbonate or other alkalinizing agents. Managing the underlying cause, such as kidney disease, is also important.
10. Renal Impairment: Treatment depends on the underlying cause but may involve managing blood pressure, blood sugar, and cholesterol levels. Dietary changes and avoiding nephrotoxic medications are also key components of care.

Recent Updates on Patiromer Research

Recent studies have focused on the long-term safety and effectiveness of Patiromer in managing chronic hyperkalemia, particularly in patients with chronic kidney disease and heart failure. A 2022 study found that Patiromer effectively maintained normal potassium levels over a 52-week period, with a low incidence of side effects. Another ongoing clinical trial is exploring Patiromer’s potential benefits in preventing hyperkalemia in patients taking renin-angiotensin-aldosterone system (RAAS) inhibitors, which are commonly used to treat heart failure and chronic kidney disease.

These findings suggest that Patiromer may be a valuable long-term option for patients at risk of hyperkalemia. However, further research is needed to fully understand its role in different patient populations. If you have questions about whether Patiromer is right for you, our telemedicine providers are available to discuss your treatment options.
