Can Dexa Pico and Phlegamine syrups be given alternately?

Such a combination is not advisable. Inhibiting a wet, productive cough with Dexa Pico syrup can make it difficult to get rid of residual secretions and aggravate the infection. If absolutely necessary (e.g. there is a choking cough at night), you can give your child Dexa Pico just before bedtime or at night (if the cough makes it difficult to sleep). Phlegamine during the day - the last dose no later than 4 hours before bedtime. I enclose a link to a helpful entry: https://www.gdziepolek.pl/artykuly/kaszel-suchy-i-mokry-jak-go-leczyc
