Can bisoprolol cause tiredness or fatigue?
Yes. Bisoprolol (a beta-blocker) can cause tiredness, sleepiness, or low energy in some people. This is a common reason people feel “wiped out” after starting the medication or after dose increases.
Why would bisoprolol make you feel tired?
Bisoprolol lowers heart rate and reduces the effects of adrenaline on the heart and circulation. For some patients, that can also reduce how strongly the body feels “driven” during activity, leading to fatigue or sluggishness, especially early in treatment or when the dose is increased.
When does tiredness usually happen, and does it go away?
Tiredness is most likely to show up when you first start bisoprolol or shortly after your dose is increased. In many cases, the body adjusts over time and the feeling improves. If it keeps getting worse or doesn’t improve after a period of adjustment, it’s worth discussing with your clinician.
What signs mean the tiredness could be from something more serious?
Seek medical advice promptly if tiredness comes with symptoms such as:
- dizziness or fainting
- very slow pulse
- shortness of breath that is new or worsening
- chest pain
- confusion or severe weakness
These can point to your dose being too high for you, slow heart rate, or another problem that needs evaluation.
What can you do if bisoprolol makes you tired?
Don’t stop the drug on your own. Options your prescriber may consider include:
- adjusting the dose
- changing the timing (some people do better taking it in the morning or evening—ask your clinician)
- reviewing other medicines that can also cause tiredness
If you tell your clinician your pulse rate and when the fatigue happens (for example, mornings vs. after exertion), it can help guide changes.
Could other causes be responsible for the tiredness?
Yes. Fatigue can also come from the condition bisoprolol is treating (like heart failure or blood pressure issues), other medications, poor sleep, anemia, thyroid problems, or depression. Your doctor can sort this out if symptoms persist.
