Metoprolol half life

Common Questions and Answers about Metoprolol half life


Avatar f tn If you take more than one in a 24 hour period, the effect of the drug is additive due to its long half life. Please be careful!
443862 tn?1238003039 Is anyone taking metoprolol? It's driving me nuts! I do have anxiety disorder. And of course knowing they gave me this to lower my heart rate makes me nervous. And with my anxiety disorder I am taking my blood pressure every hour. I know that doesn't help. But dealing with the metoprolol, it has dropped me to 88/55 at times, today 112/73, then 93/55 then 142/70. I get hot flashes, shakes, tingling arms, a general feeling of panic when I see my reading is low or I feel the shakes....
1933354 tn?1323366434 pills of each medication, you are loosing a great deal of the latter drug's effectiveness as the day wears on. The half life of Metoprolol Tartrate is only 3-7 hours. So you must take it at least twice a day for it to be effective the entire 24 hour period. Also 25mg., once a day is a a very small dose. I'm currently on 75mg as a maintenance doseage, and have been as high as 200mg. Just something to keep in mind.
Avatar f tn 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.
1423357 tn?1511089042 Just to show I under stand at 12 hours the 12 hour half life is at half strength while an 8 hour half life is close to 3/8th strength at 12 hours. - off the "top of the head"... sounds about right. How do we beat this???? I find the fact that I occasionally forget to take my medications sort of resets my residual levels to near zero...
Avatar f tn Adenosine is very short acting with a half life of only seconds, so I really doubt it would have long standing side effects, but I am not a doctor.
Avatar m tn 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.
Avatar m tn Yes... You did tell me that. But i chose to take my drs orders instead - mostly bc as someone who constantly monitors my Bp and hr, I don't find it necessary to take twice a day. My heart rate stats around 70 and my Bp stays around 100/70 all day, I find no need to introduce even more of a drug into my body when I've been on the metrication for quite some time with normal readings when only taking it once every 24 hr....
9870921 tn?1481262567 Thanks Tom, I have read many of your post and was so inspired by your attitude and how you conquered your problems, I just pray mine will be as successful as your . Ive been on mine since May 22nd and have tried to come down to 50mg twice a day but my tacky doesn't like it, and I have made about 6 trips to the ER, hopeful he will find the extra passage and fix that too.
1464004 tn?1384139333 Metoprolol has an average half life of around 5 hours. So it's metabolized fairly quickly. If one goes in for an electrophysiology study, they will be told to discontinue Metoprolol (just) 3 days before the procedure as it's quickly removed from the body. So in your case, within 12 hours your original dose of 25mg has been greatly, but not completely metabolized when you take another 25mg. Slowly, you build up a therapeutic level.
Avatar n tn I took 2 different versions of metoprolol, Toprol (metoprolol tartrate) and Toprol XL (metoprolol succinate). The second one is the extended release version. Toprol made my symtoms worse but Toprol XL worked fairly well in controlling my conditions, PVC's and PSVT. I was taking 50 mg a day in both cases. The only thing that affected me was a slight feeling of dizziness at times and some mental fatigue.
Avatar m tn Metoprolol has a rather short half life of approximately 6 hours, so in 24 hours, 50mg is nearly completely metabolized. This type should be taken twice a day. If you took the Tartrate version once a day, then the hills a valleys are smoothed out, so you have a reasonably even dosage in you system throughout the day. I can't offer you any legal advice, except "S" happens.
1464004 tn?1384139333 may hit you harder than someone,with more body mass. Also remember that Metoprolol tartrate has a half life of about 6 hours, meaning every 6 hours or so, your body metabolizes the dose to 50% of the original amount. So 25 halves to 12, then halves to 6, then to 3mg after 18 hours. You mention ablation in your profile. It could be a good way to get rid of it forever. A lot of folks here along with myself have hadn't done. Penn has sooe great docs.
Avatar m tn They all make me tired, some of them are worse and the Bisoprolol and Metoprolol are the worse for me in term of side-effects. The half-life of the Metoprolol is between 3 to 7 hours... some people are fast metabolizer and the effect will not last 7 hours and the drug will tend to not accumulate that much in the body and blood... I'm a fast metabolizer and with the Metoprolol it's even faster. I wake up around 7 AM and take 12.
Avatar n tn Cardiologist just prescribed for me to take metoprolol, half of a 25mg so 12.5mg. I'll be starting on either tonight or tomorrow morning. I do recommend talking to a gastrointestinal doctor if you think it is food or bm related like I did. It seems like the palpitations are worse as i feel food moving in my system. Then just before a bm they definitely increase. I'm hoping the metoprolol will help and not cause more symptoms...
Avatar n tn I was put on 25 mg Metoprolol (12.5mg 2x per day) on April 4, 2012 for a multicfocal atrial tachycardia event (lasted a day). Echocardiogram showed that my heart is in great shape. All was finew/ the Metoprolol (no side effects) until late July when I started losing LOTS of hair (300-400 hairs per shampooing; "normal" shedding of 75-125 when not shampooing) and now my previously thick, shiny hair is thinning rapidly and dull.
Avatar f tn My interest in Atenolol was more than the half-life of the medication. As you may have read my experience so far confirms the Atenolol is longer lasting in my body... only one sample, others may get different results.
Avatar f tn By comparison, I'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.
876405 tn?1243511886 Here's the question- I am wondering if these PVC's and PAC's that I have been experiencing in the past 2 months have to do with suddenly stopping the metoprolol that I was on for my high blood pressure. I don't recall ever getting them before and now they occurring constantly..I was taking metoprolol 25 mg twice a day and then my dr discontinued it because I found out that I was pregnant. Now I am taking something else for the blood pressure that is safe to take in pregnancy.
221122 tn?1323014865 Do you take any type of Beta Blocker for your palps? Metoprolol (Toprol) made my hair fall out BIG TIME. The hair loss is starting to slow now, 2 months after discontinuing the beta blocker....
Avatar f tn I'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?
Avatar f tn I would suggest that you try and push through the tired feeling and you have should adjust to the drug. The plasma half life of Metoprolol Tartrate is around 4 hours for most people. This means that every 4 hours, the amount of drug in your blood is diminished by 50%. Some quick math will show you that within 24 hours, there is practically nothing remaining. This also means that there is minimal therapeutic effect as the day wears on.
612551 tn?1450025775 By the way, you can compare similar weights of Metoprolol Tartrate and the time release version called Metoprolol Succicate if you consider the longer half life of the latter version.
Avatar m tn 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.
471161 tn?1317194550 Not the answer/help you're looking for, but I add my data point saying I've taken Toprol and Metoprolol in medium to high dose and have never had a chocking sensation. I do not know anything about Digoxin. If the chocking has not stopped with your discontinuation of Metoprolol I'd say it has/had nothing to do with the chocking.
Avatar f tn 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.
Avatar n tn 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.
Avatar n tn Hi - I have a question for all of you metoprolol 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!
Avatar m tn It's interesting to note that Metoprolol Tartrate has a fairly rapid half life. In approx., 5 hours after taking it, only 50% of the drug remains in your system. This is the reason you must take it twice a day to maintain a reasonable therapeutic level in your blood.
Avatar m tn 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.
