Weight gain with atenolol. What can I do?

Hi, ryirvin!
"Yes. Weight gain can occur as a side effect of some beta blockers. The average weight gain is about 2.6 pounds (1.2 kilograms)."
"Weight gain is more likely with older beta blockers, such as atenolol (Tenormin) and metoprolol (Lopressor, Toprol-XL).
"The good news is that weight gain tends to occur in the first few months after beginning the drug and then generally stops."
"If you're taking a beta blocker for heart failure, tell your doctor immediately if you suddenly gain more than 2 to 3 pounds (about 1 to 1.4 kilograms) in a day or 5 pounds (about 2.3 kilograms) in a week.
This sudden weight gain may mean that fluid is building up in your legs, abdomen or chest, which may signal that your heart failure is worsening. Your doctor can help distinguish weight gain from the buildup of fluid that may occur in heart failure."

I think it's important that you contact your doctor and get their professional advice about adjusting your dosage or changing medications.
