Key takeaways
Metoprolol tartrate (Lopressor) and atenolol (Tenormin) are both beta blockers used to treat high blood pressure, chest pain, and to lower the risk of death after a heart attack. One key difference is that metoprolol tartrate is typically taken twice daily, while atenolol is usually taken once daily. Metoprolol tartrate should be taken with food to reduce side effects, whereas atenolol can be taken without regard to meals. Metoprolol tartrate is available in both immediate-release and extended-release forms, while atenolol is only available in an immediate-release form. Both medications can cause dizziness and tiredness, but atenolol is more likely to cause cold hands and feet. Additionally, atenolol is not recommended during pregnancy or breastfeeding, while metoprolol tartrate may be an option for breastfeeding mothers. Both medications are available as lower-cost generic versions.
