The precautions for the use of mannitol include checking the drug, controlling the drug concentration, cautious use in special populations, observing drug reactions, etc. It is necessary to consult a formal hospital in time and strictly follow the doctor's advice on medication. Here are the details:

1. Checking the Drug

Mannitol may form crystals when exposed to cold temperatures. If there are crystals in the drug, it may affect the use of the drug. The drug with crystals needs to be dissolved in hot water or shaken vigorously for dissolution.

2. Controlling Drug Concentration

Doctors will adjust the concentration of mannitol based on the severity of the patient's condition to avoid too low or too high concentrations, which are not conducive to improving the condition. If the drug concentration is too high, it may increase the risk of dehydration and electrolyte imbalance.

3. Cautious Use in Special Populations

Those with cardiopulmonary function impairment, hyperkalemia, and renal failure need to be cautious when using mannitol, as blind medication may exacerbate their condition and is not conducive to improving it. Special populations such as pregnant women, lactating women, and children should avoid using the drug.

4. Observing Drug Reactions

Mannitol may induce abnormalities such as dehydration, blood pressure drop, and electrolyte imbalance after administration. It is necessary to observe the body's changes after taking the drug. If any abnormalities occur, stop the medication immediately. In addition, the precautions also include complication management, drug poisoning, and other aspects, which can be improved through various methods such as stopping medication and gastric lavage treatment in time. During treatment, it is necessary to pay attention to changes in the body and regularly return to the hospital for review.
