Usual Adult Dose for Diabetes Type 2

Oral Tablets:
Initial dose: 3 mg orally once a day for 30 days; then 7 mg orally once a day
-Titration: If additional glycemic control is needed after at least 30 days at 7 mg/day, may increase to 14 mg orally once a day
Maintenance dose: 7 to 14 mg/day
Maximum dose: 14 mg/day (taking two 7 mg tablets to achieve a 14 mg dose is not recommended)

Subcutaneous Administration:

Maintenance dose: 0.5 to 1 mg subcutaneously once a week
Maximum dose: 1 mg/week

Switching between Subcutaneous Administration and Oral Tablets:
-Patients receiving 14 mg orally once a day can be transitioned to 0.5 mg subcutaneously once a week; subcutaneous administration should start after their last oral dose
-Patients receiving 0.5 mg subcutaneously once a week can be transitioned to 7 or 14 mg orally once a day; oral therapy should start up to 7 days after their last subcutaneous injection
-No equivalent oral dose is recommended to replace a subcutaneous dose of 1 mg weekly

Comments:
-Doses of 0.25 mg subcutaneously once a week and 3 mg orally once a day are intended for treatment initiation and are not effective doses for glycemic control.
-This drug is not recommended as a first-line therapy due to the uncertain relevance of rodent C-cell tumor findings to humans.
-This drug has not been studied in patients with a history of pancreatitis; other antidiabetic therapies should be considered in these patients.

Use: As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Precautions

US BOXED WARNING: Risk of Thyroid C-Cell Tumors:
-In rodents, this drug causes dose-dependent and treatment-duration dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether this drug causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC) in humans, as the human relevance has not been determined.
-This drug is contraindicated in patients with a personal or family history of MTC and in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
-Counsel patients regarding the risk of MTC and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients receiving this drug.

CONTRAINDICATIONS:
-Hypersensitivity to active substance or any product components
-Personal or family history of medullary thyroid carcinoma (MTC)
-Patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)

Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.

Dialysis

No adjustment recommended with ESRD; however, no specific data is available for dialysis

Other Comments

Administration advice:
Oral Tablets:
-Take orally with no more than 4 ounces of plain water at least 30 minutes before the first food, beverage, or other oral medications of the day; waiting less than 30 minutes or taking with food, beverages other than plain water will decrease the absorption of this drug; waiting more than 30 minutes to eat may increase the absorption of this drug
-Swallow whole, do not split, crush or chew tablets
-Taking two 7 mg tablets to achieve a 14 mg dose is not recommended
MISSED DOSE: If a dose is missed, skip the missed dose and resume regular schedule

Subcutaneous Injection:

-Administer on the same day each week; may give at any time of the day, with or without meals
-When administering with insulin, administer as separate injections; it is okay to give in the same body region, but the injections should not be adjacent to each other
-Never share a pen between patients, even if the needle is changed; do not reuse or share needles or syringes between patients as this presents a risk for transmission of blood-borne pathogens
MISSED DOSE:
-If a dose is missed, administer as soon as possible within 5 days after the missed dose; if more than 5 days have passed, skip the missed dose and administer the next dose on the regularly scheduled day, resume regular once a week dosing
-Day of administration may be changed if the time between doses is greater than 48 hours

Storage requirements:
Oral:

-This drug should not be used to treat patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis as it would not be effective.

Monitoring:
-Blood glucose and hemoglobin A1C measurements should be measured periodically to assess efficacy

-Observe for signs and symptoms of pancreatitis
-Monitor for worsening diabetic retinopathy

Patient advice:
-Patients should be advised to read the US FDA-approved patient labeling (Medication Guide and Instructions for Use).
-Patients receiving subcutaneous therapy should be advised to never share a pen with another person, even if the needle is changed; patients should understand that sharing needles or syringes with another person carries a risk for transmission of blood-borne pathogens.
