Ouch, when I asked to move from the slow release BB to normal BB, Metoprolol, to save money I had no idea the half life is so short. If I understand half life that says in 8 hours my medication level is to 25% and at 12 hours (2 half lives) down to 12.5% almost the same as empty. I take every 12 hours, approximately. I'll ask my cardiologist about Antenolol, maybe it will reduce my dreaming problems too.
I take CCB to lower AFib driven high HR.
you won't be on a time release with standard metoprolol that is why you need to take it twice a day. I don't know why you have to cut in in half, Wal-Mart has generic metoprolol in 25mg tablets for $4.
No caffine or very little I mix my coffee half and half. 4. excersize couple times a week. 5. My cardiologist told me that in his opinion it is a proven fact that taking omega 3 fish oil suppliments can prevent and sometimes cure a- fib. Although it is not fda proven. 6. Stop drinking wine a liquor completely! Beer is ok but not dark or wheat Bud light works for me DONT DRINK EXCESSIVE more than two nights in a row. 7. Get good night sleep if possible. 8.
d ask my doc of course, and I know metoprolol has a short half life so maybe I just need to take the two doses a bit closer together. The pharmacist said 8-12 hours apart should be ok, but I am still getting some fast pulse in evening before my night dose.
So would it help to start taking one 25mg tablet three times a day instead of just twice? Just to make sure it's in my system longer?
The half life of metoprolo is 3-4 hours. Meaning the drug reamaining in your system is reduced by 1/2 every 3-4 hours. The duration of it's effects is 13-19 hours. Get out your calculator and do the math.
You took a very small dose for a very short time, so you should be close to having none left in your body.
If you are still "feeling" effects after your "withdrawal," call your doctor and let them know. Not everybody metabolizes at the same rate.
With some idea of the plasma half life of Metoprolol, and the dose strength, there is technically a small amount remaining. So to answer your question directly, yes, there is a cumulative buildup with each dose. But at that strength, it would take "forever" to build up. For some, the initial dose takes some getting use to. I've been on 75mg. for years, and feel no side effects of whatsoever.
Propranolol has a reportedly better shortening effect on Long Q than Metoprolol. Are you taking Metoprolol Tartrate? Metoprolol has a very short half life; typically 5 hours or so. In that time, half of it is metabolized. Physicians usually prescribe Metoprolol to be taken twice a day beca use of his. MetoprololSuccinate is the time release version, and that is taken once a day. In addition 25mg. is an exceedingly small dose.
Metoprolol 25 mg. Does it make a difference in what I'm taking, wether I can cut in half or not? The PA knows what I am taking and he told me just to cut it.
i take the metoprolol tartrate 25mg one pill a day but i take 1/2 when i wake up and 1/2 at bed time... like every twelve hours basically and it has helped me with my sinus tachy.
m on 75mg and have been as high as 200mg. If you look at the plasma half life of Metoprolol, at the end of the day, there is very little remaining in you blood. Are you taking it more than once a day? With Metoprolol Tartrate (the standard release kind) taking it only once a day creates these peaks and valleys as opposed to a more level dose.
The nurse finally told me to break the pill in half and take half in the morning and half at night. That worked a little better. I ended up eventually on Atenolol which I have taken for 6 years. I take it in divided doses, as my bp or hr goes up or down. If my hr and bp are too low, I delay a dose. But I never just skip it. So I might take between 1-1/2 tablets over the day, sometimes 2 pills. I don't think you're supposed to just stop it.
In fact, it has has groove where they give you a guide where to cut it, I just looked at my Metoprolol pills. If your doctor suggests you split the dosage in half and take one segment in the AM and the other in the PM I'd procede with great confidence.
Metoprolol has the same bradycardia effect as Atenolol, so that has to be watched. Metoprolol has a serum half life of around 5 hours, the Succinate version helps to even the rate of absorption out. Admittedly, my dosage is somewhat of a roller coaster curve, but it seems to work well for me. Since my ablation procedure, I continue to take it for mild hypertension. It is very effective for that for me, so I was just kept on it.
Hi Brooke,
I have a call into the cardiologist. I have been plagued with palpitations most of my life. I am very healthy, exercise all the time and weight is fine. I have just had a bout over the past two weeks with hundreds of skipped/fluttering beats. I've eliminated morning caffine and have wine occasionally. I did take my BP and it is 146/83. The added does of beta blocker isn't working. They will probably need to adjust meds.....thanks for your support.
Hi - I have a question for all of you metoprolol users...is it possible to gain weight on 12.5 mgs per day? :( I'm a very active 53 yo woman (cardio 60 min daily, weight training 4x a week, martial arts 3 x). How is it possible that I'm struggling to keep from gaining weight? I'm currently looking at my calorie intake and also the macro allocation, but one would think with all of the cardio, sparring and weigh training keeping the weight off would be easy!
Metoprolol Tartrate only has a half life of 3-7 hours. So basically, after 3-7 hours you have just 12mg in your blood, then after 6-14 hours 5-6mg which will then slow down in effect. I would ask your DOC if you can split the dosage to
twice a day, or change to another type of medication. I had the same issue as you for years, trying to balance my meds. Finally, we now have the medication to exactly the right amounts. Each morning I now take 2.
If it adversely affects you, stopping it will quickly eliminate it from your body. Metoprolol has a short half life of around 5 hours so it is metaboloized rather quickly, and its effect on you will quickly disappear.
Metoprolol has a relatively short half life of 3 to 7 hours. In other words, when you take it, its medicinal benefit begins to lessen rather quickly. By taking it only once a day, you get a spike followed by a rapid lessening of its effect. People taking Metoprolol Tartrate usually take if twice a day to maintain a relatively stable level of the drug in their system.
Another thing I wanted to point out is your dosage is extremely low. Body mass could play a factor on your dose.
