Hello thanks for asking from HCM
You have been on
Paroxetine 20 for last 15 years. As anxiety developed again so you were advised to take 40 mg Paroxetine but you started with 25 mg and then upped the dose to 30 mg. Even after that you developed severe anxiety and panic attacks. As per my opinion on possibility of such severe anxiety is sudden increase in dose of paroxetine but you are taking the drug since last 15 years so this could not be the sole reason. Even on paroxetine you are having severe anxiety. In such case I would advise you to visit your
psychiatrist again for evaluation. Medicines like lost dose Benzodiazepines can help you, but you didn't get relief. Other medicines like
Propranolol can help in reducing such symptoms. The drug is a
beta blocker drug and helps to reduce symptoms of severe panic attacks. You can discuss with your psychiatrist for the prescription of drug.
Apart from that
behaviour therapy and relaxation exercises like
Progressive Muscle Relaxation Exercises, Breathing Exercises help to reduce the frequency of panic attacks.
Persistent panic attacks even on medicines can occur due to some sub clinical
hyperthyroidism. High thyroid levels can be the reason for such symptoms. Angina is other possible medical reason. Discuss with your psychiatrist to rule out these conditions.
Thanks, hope this helps you
