Diabetic nerve damage can affect people with type 1 or type 2 diabetes. No one yet knows exactly what causes the nerve damage. Having high blood sugar (glucose) levels over time is likely to be involved. People who have had problems controlling their blood sugar levels, have high blood pressure, are overweight, or have had diabetes for at least 25 years may also have a greater risk of developing diabetes-related nerve damage.

Fortunately, research has shown that diabetic neuropathy can be prevented through improved control of blood sugar. Some ways you can play a role in helping your loved one manage their diabetes and blood sugar include:

Your support is vital, and your loved one will appreciate your kindness and compassion.

What should I talk about with my healthcare provider?

Patients on antidepressants and their families or caregivers should watch for new or worsening symptoms, unusual 
changes in behavior, thoughts of suicide, anxiety, agitation, panic attacks, difficulty sleeping, irritability, hostility, 
aggressiveness, impulsivity, restlessness, or extreme hyperactivity. Call your healthcare provider right away if you have 
thoughts of suicide or if any of these symptoms are severe or occur suddenly. Be especially observant within the first few 
months of antidepressant treatment or whenever there is a change in dose.

You should also know that:
Suicide is a known risk of depression and some other psychiatric disorders.
Antidepressants may increase suicidal thoughts or behaviors in some children, adolescents, and young adults 
especially within the first few months of treatment or when changing the dose. No increased risk has been shown for adults 
over age 24, and risk decreased for those over age 65.
All patients starting therapy should be monitored appropriately and observed closely for new or worsening 
depression symptoms, suicidal thoughts or behavior, or unusual changes in behavior.
Cymbalta is not approved for use in patients under age 18.
Who should NOT take Cymbalta?
