For long-standing Social Anxiety Disorder, medicines like Desstar XR 50 are commonly used to reduce anxiety over time and are generally appropriate when prescribed by a doctor. Arminol 10 can help control physical symptoms like palpitations or trembling in stressful situations, while Etilaam 0.25 mg may give short-term relief from anxiety but is usually not preferred for long-term daily use because it can lead to dependence if taken continuously. Vincoma Plus is generally supportive but does not directly treat anxiety. Overall, your treatment plan seems reasonable, but after 20 years, it is important to review it regularly with your doctor to see if any adjustments are needed, especially to reduce or slowly stop medicines like etizolam if possible. In addition to medicines, therapies like counselling or cognitive behavioural therapy (CBT), along with lifestyle measures such as regular exercise, good sleep, and stress management, can make a big difference and sometimes reduce the need for long-term medication. Any changes should always be done gradually under medical guidance to avoid withdrawal or return of symptoms.
