Potassium chloride, a vital form of potassium, plays a crucial role in maintaining the body's overall health. Klor-Con, a brand name for potassium chloride, is primarily used to treat and prevent low potassium levels, also known as hypokalemia, by replenishing the body's potassium stores. This article delves into the uses, potential side effects, precautions, and other essential information regarding Klor-Con (potassium chloride).
What is Potassium Chloride Used For?
Potassium chloride is commonly prescribed to treat or prevent hypokalemia, a condition characterized by insufficient potassium levels in the blood. Maintaining a normal potassium level is essential for the proper functioning of cells, kidneys, heart, muscles, and nerves. While most individuals obtain sufficient potassium through a balanced diet, certain medical conditions, medications, or lifestyle factors can lead to potassium deficiency, necessitating potassium chloride supplementation. In addition to treating hypokalemia, potassium chloride may be used for other conditions as determined by a healthcare provider.
How Does Potassium Chloride Work?
Potassium chloride works by directly increasing potassium levels in the body. As a form of potassium, it supplements the body's existing potassium stores, helping to restore and maintain a healthy balance.
Dosage Forms and Strengths
Potassium chloride is available in various oral forms, including:
- Extended-release oral capsules: 8 mEq, 10 mEq
- Extended-release oral tablets: 8 mEq, 10 mEq, 15 mEq, 20 mEq
- Powder for oral solution: 10 mEq, 20 mEq
- Oral solution: 20 mEq/15 mL (10%), 40 mEq/15 mL (20%)
Common brand names for potassium chloride products include K-Dur, K-Tab, Klor-Con, Klor-Con M, Klotrix, Micro-K, and Slow K.

Proper Storage of Potassium Chloride
To maintain its effectiveness, potassium chloride should be stored at room temperature, ideally between 68°F and 77°F (20°C to 25°C). Brief exposure to temperatures between 59°F and 86°F (15°C to 30°C), such as during transportation, is acceptable. It is crucial to store potassium chloride in a cool, dry place, shielded from direct light, and to prevent freezing.
Common Side Effects
Like all medications, potassium chloride can cause side effects. The most commonly reported side effects include:
- Nausea or vomiting
- Diarrhea or gas
- Stomach pain or discomfort
If any of these side effects persist or become bothersome, it is essential to inform your healthcare provider.
Serious Side Effects and What to Do
While less frequent, potassium chloride can cause serious side effects that require immediate medical attention.
Severe Allergic Reactions
Potassium chloride may trigger allergic reactions, which can be serious. Discontinue potassium chloride and seek immediate medical assistance if you experience any of the following symptoms:

- Swelling of the face, lips, mouth, tongue, or throat
- Difficulty swallowing or throat tightness
- Itching, skin rash, or hives
- Nausea or vomiting
- Dizziness, lightheadedness, or fainting
- Stomach cramps
- Joint pain
High Potassium Levels (Hyperkalemia)
Potassium chloride can lead to hyperkalemia, a condition characterized by excessively high potassium levels in the blood. This risk is elevated in individuals taking certain medications or with specific health conditions. Your healthcare provider may regularly monitor your potassium levels while you are on potassium chloride. Seek immediate medical attention if you experience any of the following symptoms of hyperkalemia:
- Muscle weakness or unusual fatigue
- Slow heartbeat or feeling of skipped heartbeats
- Nausea or vomiting
- Breathing difficulties
- Abnormal heart rhythm
Intestine Bleeding or Narrowing
Potassium chloride can increase the risk of developing bleeding sores (ulcers) in the gut and may also cause the gut to narrow, increasing the risk of blockage. The risk is higher in individuals with a history of stomach ulcers or those taking anticholinergic medications. Discontinue potassium chloride and seek emergency medical help if you experience any of the following symptoms:
- Severe vomiting
- Vomiting blood
- Black or tarry stools
- Persistent stomach pain
- Stomach swelling or bloating
Warnings and Precautions
Who Should Not Use Potassium Chloride?
Individuals with the following conditions should avoid taking potassium chloride:
- Allergies: People allergic to potassium chloride or any of the ingredients in specific potassium chloride products, such as K-Dur, K-Tab, Klor-Con, Klor-Con M, Klotrix, Micro-K, Pokonza, or Slow K, should not take this medication.
- High Potassium Levels: Individuals with existing hyperkalemia should not take potassium chloride.
- Esophagus, Stomach, or Gut Problems: Individuals with conditions such as stomach or intestinal ulcers, difficulty swallowing, slow stomach emptying (gastroparesis), or intestinal blockage should avoid potassium chloride tablets or capsules. A liquid form of potassium chloride may be a more suitable option for these individuals.
Drug Interactions
Potassium chloride can interact with certain medications. Inform your healthcare provider about all prescription and over-the-counter medications, vitamins/minerals, herbal products, and supplements you are taking to avoid potential drug interactions.
Important Considerations Before Using Potassium Chloride
- Only take potassium chloride as prescribed by a healthcare provider.
- Do not share potassium chloride with others, even if they have similar conditions.
- Keep potassium chloride out of the reach of children.
- Avoid taking other forms of potassium, such as supplements or salt substitutes containing potassium, without consulting your healthcare provider.
- Do not chew, crush, or suck on potassium chloride extended-release tablets. Swallow these tablets whole with a full glass of water while eating or immediately after a meal.
- Potassium chloride extended-release capsules should be taken with a full glass of water during or immediately after a meal. If swallowing capsules is difficult, you can open the capsules and sprinkle the medicine onto soft food, such as applesauce or pudding. Swallow the soft food whole, without chewing, followed by a full glass of water or juice.
- Liquid and powder forms of potassium chloride should be mixed with about one-half cup (120 milliliters) of a cold beverage before consumption during or immediately after a meal. Use an accurate measuring device to ensure correct dosage.
- Regular blood tests and heart rhythm monitoring may be necessary while taking potassium chloride.
