What are the side effects of Chlorpheniramine?

Generally speaking, "Purmin" refers to chlorpheniramine maleate tablets, whose side effects include drowsiness and dizziness, dry mouth, inattention, gastrointestinal discomfort, and difficulty urinating. It is recommended to use this medication under the guidance of a physician. A detailed explanation is as follows:

1. Drowsiness and Dizziness

As an antihistamine, this medication easily crosses the blood-brain barrier into the central nervous system, suppressing its activity, which can lead to significant drowsiness and dizziness in patients, affecting their daily work and lifestyle.

2. Dry Mouth

Chlorpheniramine maleate tablets may inhibit the secretion of glands such as the salivary glands, reducing saliva production in the mouth, thereby causing a dry mouth sensation. In severe cases, this may affect swallowing and speech.

3. Inattention

The inhibitory effect of chlorpheniramine maleate tablets on the central nervous system may decrease brain alertness and reaction capability, making it difficult for patients to concentrate and increasing the likelihood of errors during tasks requiring high levels of focus.

4. Gastrointestinal Discomfort

This medication may interfere with normal gastrointestinal motility and digestive juice secretion, causing symptoms such as nausea, vomiting, and abdominal discomfort, thus disrupting normal digestion and absorption functions.

5. Urinary Difficulty

Chlorpheniramine maleate tablets have certain anticholinergic effects, which may cause relaxation of the bladder detrusor muscle and contraction of the urethral sphincter muscle, leading to difficulty in urination, particularly more common in elderly male patients.

In daily life, while taking chlorpheniramine maleate tablets, to prevent accidents caused by central nervous system depression, alcohol consumption should be avoided, adequate rest should be taken, and engaging in hazardous activities or operations should be avoided.
