Brand Names: Klor-Con
What is Klor-Con?
Klor-Con contains potassium chloride, a mineral that is found in many foods and is needed for several functions of your body, especially the beating of your heart.
Klor-Con is used to prevent or to treat low blood levels of potassium (hypokalemia). Potassium levels can be low as a result of a disease or from taking certain medicines, or after a prolonged illness with diarrhea or vomiting.
Klor-Con may also be used for purposes not listed in this medication guide.
You should not use Klor-Con if you have high levels of potassium in your blood (hyperkalemia), or if you also take a "potassium-sparing" diuretic.
To be sure Klor-Con is helping your condition, your blood may need to be tested often. Your heart rate and rhythm may also be checked using an electrocardiograph or ECG (sometimes called an EKG) to measure electrical activity of the heart. Do not miss any scheduled appointments.
Serious side effects of potassium include uneven heartbeat, muscle weakness or limp feeling, severe stomach pain, and numbness or tingling in your hands, feet, or mouth.
Do not stop taking Klor-Con without first talking to your doctor. If you stop taking potassium suddenly, your condition may become worse.
Do not crush, chew, break, or suck on an extended-release tablet or capsule. Swallow the pill whole. Breaking or crushing the pill may cause too much of the drug to be released at one time. Sucking on a potassium tablet can irritate your mouth or throat. Take Klor-Con with food or just after a meal.
Before taking this medicine
You should not use Klor-Con if you are allergic to potassium chloride, or if:
you have high levels of potassium in your blood (hyperkalemia); or
you take a "potassium-sparing" diuretic (water pill) such as amiloride, spironolactone, or triamterene.
To make sure Klor-Con is safe for you, tell your doctor if you have ever had:
high blood pressure;
liver or kidney disease;
a large tissue injury such as a severe burn;
an electrolyte imbalance (such as low levels of calcium or magnesium in your blood);
stomach bleeding, an ulcer, or a blockage in your stomach or intestines;
an adrenal gland disorder;
Tell your doctor if you are pregnant or breast-feeding.
How should I take Klor-Con?
Take Klor-Con exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Take Klor-Con with a full glass of water. Take the medicine with food or just after a meal.
Swallow Klor-Con extended release tablets or sprinkle capsules whole without crushing, chewing or sucking. Sucking on the pill could irritate your mouth or throat.
You can mix the microcapsules from a Klor-Con sprinkle capsule with soft food, such as applesauce or pudding. The mixture must be swallowed immediately without chewing and followed with a glass of cool water or juice to ensure complete swallowing of the microcapsules. Carefully follow your doctor's instructions.
Klor-Con is also available in a powder form to be mixed into an oral solution. Mix the powder with at least 4 ounces (one-half cup) of cold water or fruit juice before taking. Drink the mixture slowly, over 5 to 10 minutes in all. To make sure you get the entire dose, add a little more water to the same glass, swirl gently and drink right away.
To be sure this medicine is helping your condition, you may need frequent blood tests. You may not notice any change in your symptoms, but your blood work will help your doctor determine how long to treat you with Klor-Con. Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG). Even if you have no symptoms, tests can help your doctor determine if this medicine is effective.
Your treatment may include a special diet. Follow the diet plan created for you by your doctor or nutrition counselor. Get familiar with the list of foods you should eat or avoid to help control your condition.
Potassium-rich foods include: squash, baked potatoes (skin on), spinach, lentils, broccoli, Brussels sprouts, zucchini, kidney or navy beans, raisins, watermelon, orange juice, bananas, cantaloupe, and low-fat milk or yogurt. Consume only the daily amounts recommended by your doctor or nutrition counselor.
Store at room temperature away from moisture and heat. Keep the medication in a closed container.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include stomach pain, vomiting, irregular heartbeats, chest pain, muscle weakness, loss of movement, numbness or tingling, or feeling light-headed.
What should I avoid while taking Klor-Con?
Do not use potassium supplements or other products that contain potassium, unless your doctor has told you to. Salt substitutes or low-salt foods often contain potassium. Read the label of any food or medicine to see if it contains potassium.
