A sachet is a small, single-dose package that contains the powdered or granulated medication. The medication is usually intended to be dissolved in water or another liquid before being taken orally. Sachets are convenient for patients as they are easy to transport and allow for precise dosing of the medication. They are commonly used for oral rehydration salts, electrolyte solutions, and other types of powders that are intended to be dissolved in liquid before consumption. Sachets can also be used for other types of medications, such as topical powders, that can be sprinkled directly onto the skin. It is important to always follow the instructions of a healthcare professional when using sachets to ensure proper dosing and to avoid any adverse reactions. Additionally, it is important to properly store sachets to protect the potency and efficacy of the medication.
