You can off-course start the Pretrax with your current medicines if your BP is still high.
It would help improve you on your BP and reduce the swelling on feet some what.
In your case I think the swelling is due to amlodipine
. Amlodipine has got a side effect of causing edema feet and swelling would resolve in 3-4 days after stopping this drug.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
