Pseudoephedrine hydrochloride sustained-release capsules refer to compound pseudoephedrine hydrochloride sustained-release capsules. Drowsiness may occur after taking compound pseudoephedrine hydrochloride sustained-release capsules.

Compound pseudoephedrine hydrochloride sustained-release capsules are primarily used to relieve symptoms of colds and influenza, such as nasal congestion, runny nose, and sneezing. This medication is a compound formulation that may contain ingredients with central nervous system depressant effects, which could lead to adverse reactions such as drowsiness or sleepiness.

During the course of treatment with compound pseudoephedrine hydrochloride sustained-release capsules, if drowsiness or sleepiness occurs, there is generally no need for excessive concern, as this is usually one of the normal adverse reactions of the medication. However, to ensure safety, it is recommended that patients avoid engaging in activities requiring high levels of concentration and precise coordination, such as driving vehicles or operating machinery, to prevent accidents caused by drowsiness.

Before taking any medication, patients should carefully read the drug's instruction leaflet to understand information regarding the drug's components, dosage instructions, adverse reactions, and other details, and use the medication appropriately under the guidance of a physician.
