Cenforce FM 100 mg is primarily used for treating erectile dysfunction and is a combination of sildenafil and fluoxetine. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, while fluoxetine is a selective serotonin reuptake inhibitor (SSRI). Typically, Cenforce FM 100 mg is not known to directly cause high blood sugar. Fluoxetine, an antidepressant, can have various side effects, but high blood sugar is not commonly reported as a direct effect. However, both medications can have a range of side effects, and individual reactions can vary. If you're experiencing high blood sugar or other unusual symptoms, it’s important to consult with your healthcare provider. They can help determine if these symptoms are related to the medication or if there might be another underlying issue.
