Veltassa (patiromer) is a medication that's used to treat high potassium levels in adults. But it isn't used for life-threatening situations when potassium levels are extremely high because it works slowly. Veltassa (patiromer) comes as a packet of powder that you mix with water and then drink; generally, you only need to take one dose per day. Common side effects include bowel changes, like constipation or diarrhea. Veltassa (patiromer) is only available as a brand-name medication; there's no lower-cost generic option currently.
Treatment of high potassium levels (hyperkalemia) in adults
Veltassa (patiromer) is a potassium binder. It works by binding (attaching) to potassium in your stomach and intestines (gut) so that your body can't absorb it. It's then passed through your stool. This lowers the levels of potassium in your blood.

You can take Veltassa (patiromer) with or without food.
Make sure to separate Veltassa (patiromer) from other medications (3 hours before or 3 hours after). Veltassa (patiromer) can change the way other medications work in your body.
Don't take Veltassa (patiromer) directly in its dry form. Always mix it with water or soft foods before taking it to make sure you get the full dose and that it works the best for you.
If you get severe constipation, don't take Veltassa (patiromer) without talking to your provider first to make sure it's safe for you to continue taking.
Let your provider know if you feel unwell (e.g., diarrhea, lower appetite) because this puts you at risk for low potassium and magnesium levels. Your dose of Veltassa (patiromer) might need to be changed during this time. Or if your magnesium levels are too low, you might need to start taking a magnesium supplement.
Make sure to tell your provider about all the medications you're taking or planning to take. Veltassa (patiromer) can lower your potassium and magnesium levels. Some other medications can change your potassium levels or magnesium levels as well.
Store Veltassa (patiromer) packets in the refrigerator. You can also store the packets at room temperature, but you have to use them within 3 months. If they're stored at room temperature for longer than 3 months, throw them away and ask your provider or pharmacist for a refill.
How to prepare and take your Veltassa (patiromer) dose:
Follow the directions to prepare and take your Veltassa (patiromer) dose properly and safely. Ask your provider or pharmacist if you have any questions about how to take the medication.
Measure one-third cup of water, and pour half of it into an empty glass. Add the Veltassa (patiromer) powder and stir. Then, add the remaining water and stir well (the powder won't dissolve and the mixture will look cloudy). You can add more water to the mixture to make it easier for you to drink. Stir well and drink the mixture right away.
If there's any powder left in your glass after drinking, add more water, stir, and drink again. Repeat until there isn't anymore powder in the glass. This is to make sure you take the entire dose.
You can mix Veltassa (patiromer) with soft foods (e.g., applesauce, yogurt, pudding) instead of water. But make sure to check the ingredients so you're not mixing Veltassa (patiromer) with soft foods or drinks with a high potassium content. Never add the powder to hot foods or liquids, or heat up the mixture (e.g., microwaved).
Veltassa (patiromer) 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.
Don't use Veltassa (patiromer) if you have stomach problems, like bowel obstruction (blockage in your gut) or severe constipation, without talking to your provider first. It's not known whether Veltassa (patiromer) works well for people with these conditions. It's also possible for Veltassa (patiromer) to worsen these conditions.
Risk factors: Stomach symptoms (e.g., vomiting, diarrhea) | Starting medications that lower potassium or magnesium levels
Taking Veltassa (patiromer) puts you at risk for low potassium levels (hypokalemia) and low magnesium levels (hypomagnesemia). Don't start any new medications while taking Veltassa (patiromer) without talking to your provider first. Some medications can further lower your potassium levels (e.g., loop diuretics), and other medications can lower magnesium levels even more (e.g., reflux medications like omeprazole (Prilosec), thiazide diuretics).
If you have any of the risk factors listed above before and during treatment with Veltassa (patiromer), contact your provider. You might need to have your Veltassa (patiromer) dose lowered or get your blood drawn to check your potassium or magnesium levels. If your magnesium levels are too low, your provider might recommend you to start taking magnesium supplements to get your levels back closer to normal.
Symptoms of hypokalemia or hypomagnesemia include muscle weakness, muscle spasms, tiredness, or tingling or numbness of your body. If you experience any of these symptoms, contact your provider.
The typical starting dose is 8.4 grams by mouth once per day. Your provider will change your dose based on how your potassium levels change with treatment and whether you're having side effects. The maximum dose is 25.2 grams in a 24-hour period.
