Prozac may reduce Exercise-Related low blood sugar in type 1 diabetes
NCT ID NCT01672255
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This early study tests whether the antidepressant fluoxetine (Prozac) can improve the body's nervous system response during exercise in people with type 1 diabetes. Many with diabetes avoid exercise due to fear of low blood sugar. The study includes 64 adults—half with type 1 diabetes and half healthy—who take either Prozac or a placebo for 6 weeks. Researchers measure stress hormone levels during exercise to see if Prozac helps the body respond better.
