Expigen Cough Syrup is generally considered safe and effective for relieving cough and congestion, but like most cough syrups, it may cause side effects in some people[2].
Common side effects associated with cough syrups and expectorants (such as guaifenesin and dextromethorphan, which are typical active ingredients in such products) can include:
- Drowsiness or dizziness[1]
- Headache[3]
- Nausea or vomiting[1]
- Constipation[3]
- Stomach pain or gastrointestinal upset[1]
- Tiredness (fatigue)[3]
- Rash (possible allergic reaction)[3]
Less common or rare side effects may include:
- Blurred vision[1]
- Confusion[1]
- Difficulty urinating[1]
- Shakiness or lack of coordination[1]
- Abdominal pain or diarrhea[1]
- Unusual excitement, nervousness, restlessness, or irritability (severe)[1]
Children and older adults may be more sensitive to side effects such as drowsiness, dizziness, confusion, and difficulty urinating. In some cases, young children might experience agitation or excitement instead of drowsiness[5].
If you experience severe or persistent side effects, or if you have underlying health conditions such as asthma, glaucoma, or enlarged prostate, consult your healthcare provider before using Expigen Cough Syrup[5]. Always follow the recommended dosage.
