1. What is Veltassa and what is it used for

Veltassa is a medicine that contains patiromer as the active substance.

This medicine is used to treat adults and adolescents from 12 to 17 years of age with high levels of potassium in the blood.

Too much potassium in the blood can affect the way nerves control muscles; this can cause weakness or even paralysis. High levels of potassium can also cause an abnormal heartbeat, which can have serious effects on your or your child's heart rhythm.

This medicine works by binding to potassium in the intestine, which prevents potassium from entering the bloodstream and reduces potassium levels in the blood to restore normal levels.

2. What you need to know before taking Veltassa

Do not take Veltassa

• If you or your child are allergic to patiromer or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before starting to use Veltassa if you or your child:

• have problems swallowing. If you cannot swallow the medicine, it will not work.
• have severe stomach or intestinal problems. This medicine can cause constipation or diarrhea in some patients.
• have had major stomach or intestinal surgery. This medicine works through the intestine, so major surgery in this area may reduce its effect.

The level of magnesium in the blood may decrease when taking this medicine. Your doctor will monitor the magnesium level during treatment with this medicinefor at least 1 month and may prescribe a magnesium supplement if necessary.

Children and adolescents

Do not give this medicineto children under 12 years of age, as it has not been studied in this age group.

• telmisartan, bisoprolol, carvedilol, nebivolol: medicines to treat high blood pressure and heart problems.

This medicine is given once a day. The recommended initial dose of this medicine varies with age. Several sachets may be used to achieve the desired dose. Your doctor may adjust the daily dose based on your or your child's blood potassium level, up to a maximum dose of 25.2 g per day.

Adults

Initial dose:8.4 g of patiromer (the contents of one 8.4 g sachet) once a day.

Adolescents from 12 to 17 years of age

• Initial dose:4 g of patiromer (the contents of four 1 g sachets) once a day. Switch to 8.4 g patiromer sachets if doses above 7 g are needed.

Your doctor will determine the duration of treatment based on your blood potassium level.

Use this medicine at least 3 hours before or after taking other oral medicines, unless your doctor or pharmacist tells you otherwise.

Method of administration

Before taking this medicine, it must be mixed with water, as described below. The volume of water depends on your dose:

• 1 g of patiromer: 10 ml (2 teaspoons)
• 2 g of patiromer: 20 ml (4 teaspoons)
• 3 g of patiromer: 30 ml (6 teaspoons)
• 4 g of patiromer: 40 ml (3 tablespoons)
• More than 4 g of patiromer: 80 ml (6 tablespoons)

Prepare the mixture by following these steps:

• Pour half of the water into a glass, add the required number of Veltassa sachets, and mix.
• Add the remaining half of the water and mix well. The powder does not dissolve but forms a suspension that can be felt as granular.
• You can add more water to the mixture to help you swallow the medicine. Note that with a larger volume, the powder may settle more quickly.
• Drink the mixture within 1 hour of preparation.If powder remains in the glass after drinking the contents, add more water, mix, and drink immediately. You may need to do this again to ensure you have taken all the powder.

If you prefer, you can use the following liquids or soft foods instead of water to prepare the mixture, following the same steps as above: apple juice, cranberry juice, pineapple juice, orange juice, grape juice, or pear juice, apricot or peach nectar, yogurt, milk, thickener (e.g., cornstarch), applesauce, chocolate pudding, or vanilla pudding.

If you use these liquids and foods, you or your child must follow the recommendations for potassium intake in your diet. If you are unsure, ask your doctor or pharmacist.

Only drink cranberry juice in small amounts (less than 400 ml per day), as it may affect other medicines.

Use the prepared Veltassa suspension with or without food, preferably at the same time every day. Neverheat this medicine or add it to hot foods or liquids.

Do not takethis medicine as a dry powder.

If you use a nasogastric tube or a percutaneous endoscopic gastrostomy (PEG) tube, follow the steps described above to prepare the suspension for oral administration. For doses up to 8.4 g of patiromer, use the volume described above. For doses above 8.4 g and up to 16.8 g of patiromer, use a total volume of 160 ml (12 tablespoons), and for doses above 16.8 g and up to 25.2 g of patiromer, use a total volume of 240 ml (18 tablespoons). These volumes ensure that the suspension flows easily through the tubes.

Polyurethane, silicone, and polyvinyl chloride tubes can be used. The recommended tube diameter is 2.17 mm (6.5 Fr) or larger. After administration of the suspension, the tube should be flushed with water. Follow the manufacturer's instructions for the tube.

If you take more Veltassa than you should

Stop using this medicine and talk to your doctor or pharmacist immediately.

If you forget to take Veltassa

If you or your child forget to take a dose, take it as soon as possible on the same day. Do not take a double dose to make up for forgotten doses. If you forget more than one dose, contact your doctor.

If you stop treatment with Veltassa

Do not stop using the medicine without your doctor's approval, as the level of potassium in the blood may increase.
