Warnings for Some Serious Health Conditions:

For people with Asthma/ Chronic Obstructive Pulmonary Disease (COPD):

  • People with asthma or COPD should generally avoid atenolol. If prescribed, it's usually in small doses with careful monitoring, as higher doses can worsen asthma or COPD symptoms by narrowing the airways. This occurs because atenolol blocks beta receptors in the heart cells, which, in higher doses, can affect the beta receptors in the airways.

For people with Diabetes:

  • The indicators of dangerously low blood sugar levels can be difficult to detect since atenolol can conceal them, including tremors and an elevated heart rate.

For people with Poor Circulation:

  • Poor circulation in your feet and hands may worsen with atenolol, as it reduces blood pressure, potentially limiting blood flow to these areas.

Storage of Atenolol

  • Protect your medication from heat, air, and light to prevent damage and harmful effects.
  • The medication should be kept at room temperature, ideally between 68 and 77 degrees Fahrenheit (20 and 25 degrees Celsius), and out of the reach of minors.
  • Consult your doctor before taking Atenolol and seek medical assistance immediately if you experience any problems or side effects.
  • Carry your medication while traveling to address any emergencies promptly.
  • Adhere to your prescription and follow your doctor's advice when taking Atenolol.
