Carcinogenesis, Mutagenesis, And Impairment Of Fertility
Studies in rats at doses of up to 5000 parts per million (ppm) in complete feed (approximately 340 times the maximum recommended human dose, based on surface area) for 30 months showed no evidence of carcinogenesis. In mice, administration of Getryl for 24 months resulted in an increase in benign pancreatic adenoma formation that was dose-related and was thought to be the result of chronic pancreatic stimulation. No adenoma formation in mice was observed at a dose of 320 ppm in complete feed, or 46-54 mg/kg body weight/day. This is about 35 times the maximum human recommended dose of 8 mg once daily based on surface area.
Getryl was non-mutagenic in a battery of in vitro and in vivo mutagenicity studies (Ames test, somatic cell mutation, chromosomal aberration, unscheduled DNA synthesis, and mouse micronucleus test).
There was no effect of Getryl on male mouse fertility in animals exposed up to 2500 mg/kg body weight ( > 1,700 times the maximum recommended human dose based on surface area). Getryl had no effect on the fertility of male and female rats administered up to 4000 mg/kg body weight (approximately 4,000 times the maximum recommended human dose based on surface area).

Is Getryl safe to take if I'm pregnant or breastfeeding?
- In animal studies, Getryl and other sulfonylureas were associated with a higher risk of fetal death. However, there have been no good studies in women. Abnormal blood sugar concentrations (high or low) during pregnancy increase the risk of abnormalities in the fetus. Therefore, physicians must carefully weigh the benefits and risks of sulfonylurea treatment during pregnancy. Insulin is the drug of choice for treating diabetes in pregnant women.
- It is not known if Getryl is excreted in breast milk like other sulfonylureas. Because of the risk of low blood sugar in the infant, it is recommended that Getryl be discontinued in nursing mothers. If therapy other than diet and exercise is needed, insulin is preferred.
These drugs can increase the effect of Getryl and cause low blood sugar. Examples of these drugs include:
- ciprofloxacin (Cipro)
- levofloxacin (Levaquin)
What are the possible side effects of Getryl (Amaryl)?
Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
Call your doctor at once if you have:
- pale or yellowed skin, dark colored urine;

OTHER NAME(S): Getryl Tablet
Getryl is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. It may also be used with other diabetes medications. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Getryl belongs to the class of drugs known as sulfonylureas. It lowers blood sugar by causing the release of your body's natural insulin.
Mechanism of Action
Getryl primarily lowers blood glucose by stimulating the release of insulin from pancreatic beta cells. Sulfonylureas bind to the sulfonylurea receptor in the pancreatic beta-cell plasma membrane, leading to closure of the ATP-sensitive potassium channel, thereby stimulating the release of insulin.
What happens if I overdose (Amaryl)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A Getryl overdose can cause life-threatening hypoglycemia.
Symptoms of severe hypoglycemia include extreme weakness, confusion, tremors, sweating, fast heart rate, trouble speaking, nausea, vomiting, rapid breathing, fainting, and seizure (convulsions).
What should I discuss with my healthcare prov >
You should not use Getryl if you are allergic to it, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
To make sure Getryl is safe for you, tell your doctor if you have:
It is not known whether Getryl will harm an unborn baby. Similar diabetes medications have caused severe hypoglycemia in newborn babies whose mothers had used the medication near the time of delivery. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
It is not known whether Getryl passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
2.1 Recommended Dosing
Getryl tablets should be administered with breakfast or the first main meal of the day.
The recommended starting dose of Glimepir >Warnings and Precautions ( 5.1) and Use in Specific Populations ( 8.5, 8.6) ].
After reaching a daily dose of 2 mg, further dose increases can be made in increments of 1 mg or 2 mg based upon the patient’s glycemic response. Uptitration should not occur more frequently than every 1 to 2 weeks. A conservative titration scheme is recommended for patients at increased risk for hypoglycemia .
The maximum recommended dose is 8 mg once daily.
Patients being transferred to Getryl tablets from longer half-life sulfonylureas (e.g., chlorpropamide) may have overlapping drug effect for 1 to 2 weeks and should be appropriately monitored for hypoglycemia.
When colesevelam is coadministered with Getryl, maximum plasma concentration and total exposure to Getryl is reduced. Therefore, Getryl tablets should be administered at least 4 hours prior to colesevelam.
- Use in monotherapy or, if glycemic response to Getryl is inadequate at maximum dose, with insulin or metformin
Breastfed infants of lactating women using Glimepir >Clinical Considerations) . It is not known whether Glimepir > . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Getryl and any potential adverse effects on the breastfed child from Getryl or from the underlying maternal condition.
Monitoring for adverse reactions
Monitor breastfed infants for signs of hypoglycemia (e.g., jitters, cyanosis, apnea, hypothermia, excessive sleepiness, poor feeding, seizures).
During prenatal and postnatal studies in rats, significant concentrations of Getryl were present in breast milk and the serum of the pups. Offspring of rats exposed to high levels of Getryl during pregnancy and lactation developed skeletal deformities consisting of shortening, thickening, and bending of the humerus during the postnatal period. These skeletal deformations were determined to be the result of nursing from mothers exposed to Getryl.
