The treatment of both anxiety and sleep disorders requires the use of thorough pharmacological and non-pharmacological therapies. Anxiolytic drugs are recommended with caution because of the risk of substance dependence, and in more advanced disorders antidepressants are usually the drugs of choice. Alternative therapy may consist of herbal medicines (natural drugs). One of such preparation is Sedatif PC, which is a composite drug with several active herbal substances. This medication is particularly recommended in the case of nervousness, adverse response to stress, and in the treatment of vegetative symptoms which accompany anxiety and sleep disorders.
