Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, you should definitely continue medicines otherwise you willingness end up in hospital again.
By your history and description, you must be having congestive heart failure
(CHF) due to hypertension
CHF is likely two cause fluid retention in lungs (pulmonary edema
) and breathlessness.
Treatment of choice for this is diuretics.
If you don't take diuretics then high possibility of recurrence of pulmonary edema in future.
Along with diuretics, strict control of hypertension and asthma
So don't stop your drugs. Do regular follow up with your doctor and take medicines regularly.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
