Worried I will get a heart attack while smoking cannabis. My heart is fine but I take metoprolol for tachycardia. What would it take for heart attack?

Worried I will get a heart attack while smoking cannabis. My heart is fine but I take metoprolol for tachycardia. What would it take for heart attack?

Don't Self medicate!: I presume if your holter was normal your metoprolol is to reduce frequency of panic attacks? Your anxiety is not being treated properly and my concern is that you are "self medicating" for your underlying condition. (anxiety) Also cannabis can trigger anxiety, paranoia and psychosis! Please seek mental health help! ...Read more

On 25mgER of metoprolol for tachycardia PVC, PAC, SVT. Recently having light headedness but no heart symptoms. Dr said stop metoprolol. Ok to stop and c?

On 25mgER of metoprolol for tachycardia PVC, PAC, SVT. Recently having light headedness but no heart symptoms. Dr said stop metoprolol. Ok to stop and c?

Yes, most likely: You are young, and more importantly you need to better elucidate the type of SVT you have. IF your PCP, said stop, I would like to trust his/her judgement. You may wish to see an electrophysiologist (arrhythmia subspecialist of cardiovascular disease) to better refine your dignosis and treatment plan, if any. I suspect non-cardiac causes of high heart rate, such as thyroidfunction, dehydra, exclud ...Read more

24 weeks pregnant and drs want to put me on Metoprolol for supraventricular tachycardia. They say it's fine but online says it's pregnant cat. C! Safe?

24 weeks pregnant and drs want to put me on Metoprolol for supraventricular tachycardia. They say it's fine but online says it's pregnant cat. C! Safe?

Metoprolol: Yes, it is category C. However, your tachycardia can easily be a much bigger problem for the health of your pregnancy. During your bouts of tachycardia the blood flow to the placenta is compromised to a certain extent. Repeated bouts of tachycardia could affect the development of your baby. It is a balancing act, but taking the medicine is almost always the better choice for the pregnancy ...Read more

Have headache, stuffy nose, swollen glands, dizziness, chills, &sweating. Cold or flu? I take Lopressor (metoprolol tartrate) for Pots/tachycardia. What cold meds should I avoid?

Have headache, stuffy nose, swollen glands, dizziness, chills, &sweating. Cold or flu? I take Lopressor (metoprolol tartrate) for Pots/tachycardia. What cold meds should I avoid?

No Sudaphed: Afrin will help with nasal congestion, & when used correctly has little systemic effect. The drug alone can only be taken short time or stops working. I suggest U ask physician for prescription of Fluticosone Propionate which sprayed in nostrils & breathed in once daily can help U to take the meds longer. Reasonable to test for flu & take tamiflu if positive. Tylenol (acetaminophen) or ASA for other symptoms ...Read more

Tachycardia better after a wk of low dose metoprolol, but rhr still a lil high. How long b4 body adjusts, how soon b4 knowing if dose should be incr?

Tachycardia better after a wk of low dose metoprolol, but rhr still a lil high. How long b4 body adjusts, how soon b4 knowing if dose should be incr?

What is cause?: Did they determine cause of your tachycardia? Sometimes the best treatment is to treat the underlying cause. For example, Effexor (venlafaxine) can cause tachycardia. Perhaps they need to reduce your dose of this. Usually, metoprolol should slow down heart rate within a week. If not improving, see your doctor again. Good luck! ...Read more

Prev rhr 120-154, 1 wk metoprolol tartrate 12.5mg twice daily for tachycardia, rhr now 112. How long b4 body adjusts, how soon b4 dose incr, if any?

Time will tell: Depends, every person is different on how they take to medications. You should be ruled out for inappropriate sinus tachycardia (a diagnosis of exclusion). If everything else is ruled-out and inapp. Sinus tach is what you have, be patient this is a relatively benign condition but very difficult to treat. Good luck. ...Read more

Tachycardia of 102-116 for ten straight days no other symptoms---dangerous? Wearing patch monitor. On no medications after two years on toprol (metoprolol).

Could be: A tachycardia of that magnitude that is persistent at your age is strongly suggestive of an arrhythmia or cardiac irregularity more likely due to atrial fibrillation. You need to see your doctor as this put you at risk for stroke even if you have no symptoms. Also you need an adjustment of your medication to control your heart rate. ...Read more

Is it safe to exercise with sinus tachycardia? I'm on metoprolol ER 25mg a day.

Needs evaluation.: To help decide if it's safe to exercise, it would be important to undergo a thorough examination to determine the underlying cause of the tachycardia. Hyperthyroidism causes a rapid heart rate; there are less common medical problems which could be at fault. Finding the problem will enable the determination of the proper treatment. Then the exercise question can be answered. ...Read more

I have been taking toprol (metoprolol) for over two weeks for high BP &tachycardia. I seem to be gaining weight & am very tired. Is this normal?

I have been taking toprol (metoprolol) for over two weeks for high BP &tachycardia. I seem to be gaining weight & am very tired. Is this normal?

Tired? Yes.: Toprol's main side effect is fatigue but people usually get used it over several weeks. If you're exercising less and sitting around, possibly eating more, you'll gain weight but I wouldn't blame the toprol (metoprolol) for that. If the side effects are unacceptable, it helps to halve the dose for 2 weeks, and then build up a full dose. ...Read more

Propranolol safety in 18y/o male with tachycardia & high bld. Press? Life expectancy decreased? Side effects? Toprol (metoprolol) vs propranolol?

Propranolol safety in 18y/o male with tachycardia & high bld. Press? Life expectancy decreased? Side effects? Toprol (metoprolol) vs propranolol?

This is so common: That I despair of accurate diagnosis. Your heart and BP at 18 are controlled by the limbic system of the brain---a computer that organizes your ability to adapt to environment. Defective oxidative metabolism causes the computer to send out unnecessary signals through the sympathetic nervous system. Commonest cause is vitamin b1 and magnesium deficiency from ingestion of sugar and sweeteners. ...Read more

High: The starting dose of metoprolol varies according to the indications for its use and the exact condition of the patient. However, a starting dose of 250 mg would be high in most typical situations. Daily doses up to 400 mg and even higher are used in some situations, but not as a starting dose. ...Read more
