Does Nexpram only work in 10 or 20 mg dosage, or in smaller doses too?

Each dose has a greater or lesser effect on the body. The therapeutic effect occurs already with the use of a dose of 5 mg. According to the manufacturer: "In a 24-week study to determine the dosage, the efficacy of escitalopram at doses of 5 mg, 10 mg and 20 mg was demonstrated." The dose is determined by the doctor, depending on the symptoms, e.g. in the treatment of panic disorder: "In the first week of treatment, a starting dose of 5 mg is recommended, followed by an increase to 10 mg per day. Depending on the individual response of the patient, the dose may be increased to the maximum dose, i.e. 20 mg per day. The greatest effectiveness is achieved after about 3 months of using the product. The treatment lasts for several months." More here: https://www.gdziepolek.pl/kategorie/zaburzenia-lekowe-nerwica
