Is your potassium level high? Let's learn about this medicine Sodium Polystyrene Sulfonate!

Do you sometimes feel like you have no energy? Do you notice something different, faster, or irregular in your heartbeat? Perhaps the reason for this is that your body has too much of an essential mineral called potassium. Potassium is actually essential for our body to function properly. However, like anything, when it increases in the body, problems can arise. At such times, when the potassium level in the blood increases unnecessarily, a special medicine that doctors give us to help is called Sodium Polystyrene Sulfonate. Let's see what this medicine is and how it helps our body?

What kind of medicine is this?

Simply put, Sodium Polystyrene Sulfonate is a medicine that helps reduce the amount of excess potassium in our body. It does this very simply. When you take this medicine, it goes into your intestines and grabs the excess potassium there. It's like a magnet grabbing iron powder. Then, this captured potassium is passed out of the body with feces. Then the potassium level in the blood gradually returns to normal.

You may see this medicine under brand names like `(Kionex)` or `(SPS)`. But no matter what the name, it does the same thing. Sometimes this medicine can be used for other reasons, you can ask your doctor or pharmacist about it.

What are the things I need to tell the doctor before taking this medicine?

Before you start taking this medication, it's important to tell your doctor some important things about your health. That way, he or she can decide exactly whether this medication is right for you and how to give it. Here's what they are:

  • If you have a condition like a blockage in your bowel: This means that you have difficulty passing stools, such as a blockage somewhere in your intestines.
  • If you have constipation: If you haven't had a bowel movement in days, or if it's difficult to pass stool.
  • If you have dry, hard stools that do not pass through the anus (impaction): This means that there is a very hard, stone-like stool stuck in the rectum.
  • If you have heart failure: This means that your heart's pumping ability is slightly weakened.
  • If you have high blood pressure: This means that your blood pressure is high.
  • If you have low calcium levels in your blood, or low potassium levels (before taking this medicine): This medicine reduces potassium, so it may be a problem if those levels are already low.
  • If you are following a low sodium diet: This is important because this medicine contains sodium.
  • If you have recently undergone surgery and have had problems with your bowels after surgery.
  • If you have previously had an unusual or allergic reaction to Sodium Polystyrene, other medicines, foods, food dyes, or preservatives.
  • If you are pregnant or trying to get pregnant.
  • If you are breastfeeding a child.

This information is very important. Because the doctor can then think about your safety and advise you on the use of this medicine in a way that is right for you. So, is it better to tell everything without hiding anything?

How should I use this medicine?

This medicine is usually given to you in a hospital or clinic. That means under medical supervision. It can be given to you as a liquid to take by mouth, or sometimes rectally. However, you should follow the instructions given by your doctor or on the prescription label.

Here is something very important:

If you are taking other oral medications, you should take them 3 hours before or 3 hours after taking Sodium Polystyrene Sulfonate. Did you know that this medicine can slightly interfere with the absorption of other medications into your body?

Imagine you have a condition that delays emptying of food from your stomach to your intestine. That means it takes longer for food to move from your stomach to your intestines than normal, so you need to take other oral medications 6 hours before or 6 hours after this one. It is very important to follow these timings for the other medications to work.

Take your medicine at the right time, in the right amount. Don't take it more often than your doctor tells you to.

When to give this medicine to small children?

Special care should be taken when giving this medicine to young children. Therefore, before giving this medicine to your child, be sure to talk to a pediatrician and follow his or her instructions.

What to do if you take too much medicine? (Overdosage)

If you think you have taken too much of this medicine, call your nearest poison control center or hospital emergency room immediately. Do not take this lightly, as taking too much can cause serious problems.

Another thing, this medicine is only for you. Even if a friend or family member has the same illness as you, wouldn't it be better to not give them your medicine?

What to do if you miss a dose of medication?

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose when you remember, skip the missed dose and take your next dose at the scheduled time.

👩🏽‍⚕️ Additional questions (FAQs)

💬 What is Sodium Polystyrene Sulfonate / Kayexalate?

This is a special (powder/liquid) medicine that is given when your blood potassium levels become too high (Hyperkalemia) due to kidney problems. If potassium levels in the blood become too high, the heart can suddenly stop beating and cause death, and this prevents that fatal risk 100%.

💬 How do you absorb that potassium in your intestines after taking this medicine?

This is a chemical that works like an 'Ion-exchange resin'! After you drink this powder/liquid, it is not absorbed into the body (blood). As it passes through the intestines, the 'Sodium' in this medicine leaves them and absorbs the 'Potassium' that is increased in our blood like a sponge. Finally, all that potassium is excreted with feces (that is why the patient has diarrhea).

💬 What are the specific side effects that can occur when taking this medicine?

The biggest problem is that this is a very harsh/poisonous medicine for the intestines! Therefore, for some people, it can cause severe intestinal damage (the medicine will curdle) and lead to a fatal condition called intestinal necrosis (especially if mixed with Sorbitol). Also, when potassium is reduced, sodium (salt) in the body increases, so there is a risk of swelling in the legs and increased pressure (Fluid retention).
