Hi. I’m sorry you had to go through that. Panic attacks can feel extremely frightening, especially when they seem to come out of nowhere, but it’s reassuring that your cardiac evaluation has been normal.
Regarding the clonazepam, a dose of 0.25 mg may not always stop an ongoing panic attack immediately, and it can take some time to start working. One episode not responding doesn’t necessarily mean the treatment isn’t appropriate.
Next Steps
Since you are continuing to have recurrent panic attacks, including without any obvious trigger, I would recommend a follow-up with your treating psychiatrist rather than making changes to your medication on your own.
If you would like a second opinion, I would be happy to evaluate you in detail. During a consultation, we can go through your symptoms, medical history, previous investigations, and discuss the most appropriate treatment options for you.
Take care, and feel free to message me if you have any questions or if you’d like to schedule a consultation.
Health Tips
In the meantime, if you experience chest pain unlike your usual panic attacks, fainting, severe breathlessness, or any new concerning symptoms, please seek emergency medical care immediately.
