What are the side effects of oral potassium chloride injection?
Potassium chloride injection is an electrolyte supplement primarily used to treat hypokalemia caused by various conditions, and to prevent frequent, multifocal premature beats or rapid arrhythmias due to digitalis toxicity. Oral administration may lead to side effects such as gastrointestinal reactions, nervous system reactions, cardiac reactions, muscular reactions, and skin reactions. Specific details are as follows:
1. Gastrointestinal reactions
Patients taking potassium chloride injection orally may experience nausea, vomiting, abdominal pain, and other gastrointestinal symptoms. If the dosage is excessive or treatment duration exceeds a certain period, diarrhea may occur. Overuse of potassium chloride can elevate serum potassium levels, enhancing intestinal motility and resulting in diarrhea.
2. Nervous system reactions
Long-term oral use of potassium chloride injection may cause dizziness, irritability, and palpitations as nervous system reactions. In cases of overdose, more severe neurotoxic side effects such as loss of consciousness, somnolence, and fatigue may occur.
3. Cardiac reactions
Patients taking potassium chloride injection orally may experience palpitations and other cardiovascular symptoms. Excessively high potassium levels in the body can disrupt cardiac conduction, leading to arrhythmias, and in severe cases, symptoms of heart failure may develop.
4. Muscular reactions
Muscle soreness and pain may occur after oral administration of potassium chloride injection. This is because potassium chloride binds with potassium ions within muscle cells, causing muscle contraction and resulting in discomfort or soreness.
5. Skin reactions
Rash and itching may occur following oral intake of potassium chloride injection. The strong pharmacological properties of potassium chloride may irritate the skin and stimulate cutaneous nerves, leading to redness, itching, and rashes.
In summary, oral potassium chloride injection is highly effective in treatment, but it also carries potential side effects. Patients must strictly follow medical instructions, pay close attention to proper dosage, and take precautions to prevent adverse reactions.
