These drugs should not be combined with each other.
Acti-trin contains dextromethorphan - together with fluoxetine (the active ingredient in Seronil) may cause an increase in the concentration of dextromethorphan in the blood and consequently lead to the occurrence of m.in vomiting, headache and dizziness, fever, high blood pressure, convulsions, hallucinations or other similar symptoms. Since the risk of these types of symptoms is high, such a combination should be avoided. Acti-trin can be replaced with another syrup with an antitussive effect.
