Generalized anxiety disorder is a chronic mental health condition that needs different types of treatment depending upon the severity of the condition. Generally, a combination of psychotherapy and medications is considered the best treatment for managing the symptoms of generalized anxiety disorder. 


Psychotherapy plays a crucial role in the quick treatment of a patient with GAD. It helps discover the underlying causes of the condition, the trigger points, the responsive attitude towards the triggers, and so much more. Here are the main therapies for the treatment of different types of anxiety disorders including GAD. 

  1. Cognitive Behavioral Therapy: CBT is the most common type of behavioral therapy that aims to reduce the symptoms of depression and various types of mental health disorders. The therapy emphasizes challenging the disturbing patterns including a patient’s thoughts, beliefs, and attitudes. Moreover, it also helps you understand your trigger points and accordingly develop coping strategies to improve emotional regulation. Simply put, getting cognitive behavioral therapy helps you identify your negative or discouraging thought patterns and help them replace with realistic and positive thoughts. 
  2. Exposure Therapy: Exposure therapy is a common technique used in behavioral therapy to treat a number of conditions including anxiety disorders, specific phobias, and post-traumatic stress disorder.  In this therapy, you’re exposed to a condition that you’re afraid of and are taught the best ways to cope with the condition using a technique known as ‘systematic desensitization. It involves three steps: 
  • You will be given relaxing training to help manage your anxiety symptoms. Training includes deep breathing exercises, guided imagery, etc. 
  • The next step is to create a list of all your triggers that make you anxious and rank them in terms of their severity. 
  • In the final step, you would be exposed to your triggering conditions and will be taught step-by-step actions to combat your anxiety. 

There are many online clinics available that treat different types of anxiety disorders including generalized anxiety disorder. Websites like steady care medical are a good example. 


Below are the common types of medications used to treat generalized anxiety disorder:

  1. Antidepressants: Though antidepressants may not completely cure the disorder but greatly helps reduce symptoms. There are a bunch of antidepressants available but your doctor will recommend the ones which are best-suited to manage your symptoms. Do not take antidepressants without your doctor’s recommendation. 
  2. Benzodiazepines: Benzodiazepines are a class of drugs that are used to manage various medical conditions including anxiety, seizures, and insomnia. There are different types of benzodiazepines with slightly different uses. Too much consumption of the drug could be risky and lead to some severe side effects. Again, consult a licensed doctor before taking any type of medication. 
  3. Hydroxyzine: Hydroxyzine medications are used to manage anxiety symptoms and control muscle tension triggered by nervous and emotional conditions.  
  4. Buspirone: Buspirone belongs to the class of medications named anxiolytics and is used as a short-term treatment for anxiety disorders including GAD.  These medications help you think more clearly, relax and calm your body to easily perform your everyday tasks. 

Final Thoughts 

Summing up the entire discussion, it could be concluded that while anxiety disorders including GAD cannnot be completely cured but following the right treatment diligently could reduce the intensity of the symptoms and could highly improve one’s quality of life. If you think you have symptoms of anxiety, instead of jumping to conclusions by yourself, make sure you talk to a doctor and share your exact condition to get the best guidance.
