How to Prepare for your Infusion

What to expect when visiting a Restor Metabolix clinic

Eat a healthy, balanced breakfast before you arrive.

Take all non-diabetic medications as prescribed.

Take 1/2 dose of all oral diabetic medications and hold insulin dosage on the day of treatment.

Afternoon Appointments

Eat a healthy, balanced meal before you arrive.

The night before, take all medications as prescribed.

Take 1/2 your insulin dose on the morning of your treatment.

Take all other medications as prescribed.

Insulin Pump Users

Turn pump off two hours before treatment.

Do NOT eat breakfast if you have a morning treatment.

Turn pump back on immediately after treat is complete.

What to Eat Before You Come

Prior to a PIR infusion, it is advised to eat higher-protein meals/snacks. If a high amount of carbohydrates is consumed prior to treatment, blood glucose levels will affect the infusion. Consuming foods/snacks higher in protein will not cause extreme spikes in blood glucose levels.

Frequently Asked Questions

Do you take my insurance?
We work with most insurance plans and, of course, Medicare. However, if we are not in-network on your plan, our insurance experts will assist you in determining coverage for your services. When we get your insurance information, we can review your policy and better answer the question.
What’s the first step?
The first step is to come in for a consultation so we can review your specific situation and physical condition and help you understand how the treatment can help you individually.
What does the consultation consist of?
You will meet with a member of our medical staff who will review your medical history and physical condition and explain the treatment in more depth. This consultation is very important in creating your customized care plan. Typical consultations take 30 to 60 minutes. You may be asked to come prepared for blood work if your latest blood work is not up to date.
How often will I be taking treatments?
Everyone is different, so we rely on your individual and personalized care plan. At your consultation, our medical staff will determine your care plan and course of treatment. Care plans range from one three-hour weekly infusions to one two-hour infusion every six weeks.
Do I Need To Talk To My Doctor First?
We do not require a referral or approval from your doctor; however please note that we are not a replacement for your doctor. Instead, we prefer to work with your doctor to co-manage your individualized care plan including treatment, testing, and clinical results.
No Insurance?
Ask about cash plans and patient financing. We’d love to help!
