Hola, encuentro los efectos de 5 mg de bisoprolol por la mañana casi instantáneos, y en una hora tengo un ritmo cardíaco de 45 bpm. Pero también me siento muy cansado.
Pero hacia las 6 pm, vuelven las palpitaciones, pero no me atrevo a tomar más bisoprolol, me dejaría KO. ¿Sería seguro, crees, tomar 2.5 mg de bisoprolol por la mañana y luego solo 25 mg de atenolol a las 6 o 7 pm? Así al menos podría mantenerme despierto para ver la televisión. (Como no hay mucho más que pueda hacer, si sabes a lo que me refiero, estas pastillas me afectan "ahí abajo" 
).
Soy hombre, 55 años.
Gracias.
Can you spilt your 5mg of bisoprolol into 2.5 morning and the other 2.5 at night? I did this as I found my palpitations would kick in, in the evening if I just took it all first thing.
Gracias Sian, sí, puede que lo intente. Es solo que el Atenolol no causa somnolencia. Quizás si tomo las primeras 2.5 pastillas a las 10 y la siguiente a las 9 pm, me ayudaría a dormir.
Pero mi pobre esposa.....
Lol I share your pain but I do find 2.5 doesn't make me as tired, it may take a few days before you feel the difference
Beta blockers should be usually taken in the morning since they slow down our heart and give us a protection during the day, when a heart in general pumps faster and there is a higher chance to get an arrhythmia.
Our natural Heart rate is slower at evening and the slowest in the night while we sleep. (For example, something like 70 at noon, 60 at evening and 40-50 while sleeping at night).
Now, the point of BBs is to get a protection when your natural Heart rate is at it's highest (during the day).
During the night, our HR drops a lot, and if you take too many drugs at evening, there is a slight chance that your heart will start to beat too slow during the night and that can cause pauses and a heart attack also.
In majority of people HR won't go too low.
But in people who already have a lower natural HR during the night, Beta blockers can be dangerous.
Also, in your case, you said that Beta blockers hit you hard right away after you take the dose.
Now, if you take them too late in the evening, there is a chance for these problems which I have explained above.
The best thing would be to talk to your doc about your side effects and ask him to give you a different dose which will suit you better. Good luck
Gracias Bob,
creo que tienes razón, el BB por la noche puede hacer que baje peligrosamente bajo durante el sueño
