Fluoxetine is a medicine that can help treat depression and other mental health conditions. It belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs).
Basaglar is a long-acting insulin that helps control blood sugar levels. It is used to treat type 1 and type 2 diabetes.
Fluoxetine can treat major depressive disorder in adults and children. It also treats obsessive-compulsive disorder (OCD) in adults and children. Fluoxetine can help with bulimia nervosa (an eating disorder) and panic disorder. Sometimes, it is used with another medicine called olanzapine to treat depression related to bipolar disorder.
Basaglar is used to lower blood sugar in adults and children with type 1 diabetes. It also helps adults with type 2 diabetes manage their blood sugar. However, Basaglar is not for treating diabetic ketoacidosis, a serious condition with high levels of ketones in the blood.
Fluoxetine works by increasing the amount of serotonin in your brain. Serotonin is a chemical that helps regulate mood. By increasing serotonin, fluoxetine can help improve mood and reduce symptoms of depression, OCD, and other conditions.
Basaglar is a long-acting form of insulin. It works by replacing the insulin that your body does not make, or helping your body use insulin better. This helps to lower your blood sugar levels over a longer period.

Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, fluoxetine has 15,944 submissions while insulin glargine has 76,422.
