Something similar happened to me, back in the 90's. I had to take an MAO inhibitor for depression, and my blood pressure went up due to medication side effects -- or at least, I thought it was due to medication side effects. The blood pressure did not go back down when the medication was discontinued. My psychiatrist told me, at the time, that the people whose blood pressure does not go back down tend to be people who have other predisposing factors for hypertension. Several years later, with my blood pressure getting higher year after year, it was discovered that I had aortic valve insufficiency.
I also have been told that sometimes the blood pressure "set point" can get elevated by something like medication side effects, and then it becomes necessary to take antihypertensive medication to move the set point back to baseline. In your position, kuntaykarthik, I think I would just try to get the blood pressure back down by any means necessary. dolphin8088 had some good suggestions, above. If you should end up having to take antihypertensive medication, then perhaps after your BP has been normal for a sustained period of time, you could talk to your doctor about tapering off of the medication on a trial basis.
Are you over weight? Do you have a family history of high Blood Pressure?
Have you tried reducing your salt intake?
It may not have been the medication at all that was doing it. Many people can reduce their blood pressure without medication by making lifestyle changes such as, reducing salt intake, working out more days then not, losing weight if they have a few extra pounds on and destressing as much as possible.
You should do all this with your doctors assistance and approval. Sometimes these things do not help if there is a genetic component and medication is needed but your doctor can help you through those steps.
Good luck!
