Precautions and Warnings With Saxagliptin
If you are going to take saxagliptin, it's important to be aware of the drug's precautions and warnings before starting treatment. For example, since saxagliptin is cleared from the body using the kidneys, people with kidney problems may need to take a lower dosage. People with type 1 diabetes should not take saxagliptin, as the medicine is ineffective for this type of diabetes.
What Should I Tell My Healthcare Provider Before Using Saxagliptin?
- Kidney disease, such as kidney failure (renal failure)
- Type 1 diabetes
- Diabetic ketoacidosis
- Ever had pancreatitis (inflammation or infection of the pancreas)
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Specific Saxagliptin Precautions and Warnings
Some warnings and precautions to be aware of with saxagliptin include the following:
- Very preliminary data suggests incretin mimetics, such as saxagliptin, may increase the risk of precancerous cellular changes (called pancreatic duct metaplasia) in people with type 2 diabetes. Researchers are continuing to study the possibility that incretin mimetics might increase the risk of pancreatic cancer, although at this time there is not enough information to know for sure if there is any increased risk.
- There have been rare reports of pancreatitis in people taking saxagliptin. Based on reports of this problem with saxagliptin or other similar drugs, this is probably most likely to occur shortly after the drug is first started or when the dosage is increased. Be sure to let your healthcare provider know right away if you have signs of pancreatitis, such as:
- Loss of appetite
- Severe persistent abdominal (stomach) pain that sometimes radiates to the back.
- Saxagliptin should not be used to treat type 1 diabetes or diabetic ketoacidosis, as it is ineffective for such conditions.
- Saxagliptin is cleared from the body using the kidneys, and people with kidney problems (including people on dialysis) need to take lower doses of saxagliptin. Your healthcare provider should test your kidney function (using a simple blood test) before you start this medicine.
- The risk of low blood sugar (hypoglycemia) is low for saxagliptin. Also, taking this drug with metformin (Fortamet®, Glucophage®, Glucophage XR®, Glumetza®, or Riomet®), pioglitazone (Actos®), or rosiglitazone (Avandia®) usually does not appear to substantially increase the risk of low blood sugar.
- Combining saxagliptin with sulfonylureas increases the risk of low blood sugar (see Drug Interactions With Saxagliptin). Your healthcare provider may need to lower the dosage of your sulfonylurea. Sulfonylureas include:
- Saxagliptin is considered a pregnancy Category B medication. This means that it is probably safe for use in pregnant women, although the full risks are not known. Talk to your healthcare provider before taking saxagliptin during pregnancy (see Onglyza and Pregnancy).
- It is unknown if saxagliptin passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, be sure to talk with your healthcare provider (see Onglyza and Breastfeeding).
