If I stop taking tamsulosin how long before dizziness stops?

I stopped taking this medication about 2 days ago and still experiencing all the side effects of Tamsulosin 0.4MG. I am still having extreme Dizziness and Lightheadedness,Chest Pains & Chest Tightness, Feeling like fainting & Muscle Weakness. I am trying to get this medication out of my system as soon as possible. I took it for Kidney Stones but now I feel like it's taking forever to come out of my system... I maybe took it for about 1 week when I was on it. I am a 21 year old female and average weight. It's causing me so much anxiety and panic attacks.

All I can say is the dizziness might not stop..even after you stop taking the medication it's self. Just be super careful with this medication.

Tamsulosin is working to relax one's muscles in the prostate and bladder, so one can urinate easier.
It also helps to treat BPH in men. Dizziness happens usually because you just started taking the medication or after you increase the dosage. How long does it take for the dizziness to go away depends on your condition, weight, and height, etc. However, in the meanwhile, try not to get up so quickly after lying down can help.
