Dizziness With Feeling Lightheaded. Trying To Stop Metroprolol. How Long Does It Take To Get The Medicine Out Of The Body? Have Panic Attacks

I have been on metoprolol for less than a month I am getting weaned off. How long will I feel crappy, dizzy, and lightheaded? Also how long does it take to be completely out of my system. I started on 1/21 with 25 mg two times a day. On 1/29 I was told to start 50 mg two times a day starting with my evening dose. This was making me feel horrible and very tired. On 2/5 I was dropped to 25 mg two times a day. Yesterday my cardiologist said he is weaning me off. Last night I took 12.5 mg and will have the same dosage two times today and two times tomorrow. Saturday and Sunday I will only have one dose of 12.5 mg. nothing on Monday. I was only prescribed this because I had a panic attack my hr was up to 140. The ER diagnosed me with svt. Saw my family dr a week later and my hr was 101. ( I was nervous to get results). He then doubled my dose. My cardiologist says my heart is strong and he sees no problems. I am just wondering if this type of weaning will make me feel worse and when can I expect to feel like me again?

Hi friend,
Welcome to Health Care Magic

The blood level of any substance - including drugs - falls to negligible levels in by the end of 7th half life.
Half life of one day means half the substance will be cleared by the body in one day – in other words only 50% will remain on second day. At this rate, the reminder on day 3 = 25% / Day 4 = 12.5% / day 5 = 6.25% / Day 6 = 3.125%. / day 7 = 1.5625%

The half life of Metoprolol is about 3 to 7 hours / so, in 2 days, it will be gone!

Take care
Wishing speedy recovery
God bless
Good luck
