Can you mix simlasan cold and mucus relief with claritin (loratadine)?

?: Similasan is herbal used by homeopath, it contains senega which loosens mucus through irritation of mucus membranes, thus more mucus is produced , hence expectorated, claritin (loratadine) though decreases secretions and not meant to be an expectorant rather at times it works as a cough suppressant, at any rate if you have cold symptoms and are in doubt, rest, fluids and either medicine would help,
