Side effects
Monitor
- Apical pulse + BP before dose — know your hold parameters (often HR < 60, SBP < 100)
- Blood glucose awareness in diabetics — tachycardia warning sign is blunted
- Caution in asthma/COPD (non-selective agents can bronchospasm)
🎓 Patient teaching
Never stop abruptly — rebound tachycardia and angina. Rise slowly. Diabetics: check sugars; your usual low-sugar warning signs are muted.
