Here are the 10 most common side effects people may notice:
1. Fatigue or tiredness
One of the most frequent effects. The heart beats more slowly, so some people feel low energy, especially at the beginning.
2. Dizziness or lightheadedness
Often due to lowered blood pressure, especially when standing up quickly.
3. Slow heart rate (bradycardia)
A known effect since the drug reduces heart workload. Usually monitored by doctors.
4. Cold hands and feet
Reduced circulation to extremities can cause this feeling.
5. Shortness of breath (in sensitive people)
More likely in those with asthma or lung conditions.
6. Sleep disturbances or vivid dreams
Some people report changes in sleep patterns.
7. Depression or mood changes
Uncommon but reported in some users, especially at higher doses.
8. Digestive issues
Nausea, stomach discomfort, or diarrhea can occur.
9. Reduced exercise tolerance
You may notice getting tired faster during physical activity.
10. Sexual side effects
Reduced libido or erectile difficulties in some individuals.
