Sitagliptin Phosphate Monohydrate - Role in treating type 2 diabetes

Sitagliptin is a medicine used to treat type 2 diabetes mellitus. It is used together with a healthy diet and regular exercise to control blood sugar levels. It also helps to prevent severe complications of diabetes, like kidney damage and blindness.

Mechanism of action

It is used with immediate or extended-release metformin, given separately or as a fixed combination (Janumet or Janumet XR, respectively). Alongside a controlled diet and exercise regime, it improves glycaemic control in patients with type 2 diabetes mellitus.

Dosage and administration

The following guidelines are essential for the safe administration of Sitagliptin Phosphate Monohydrate.

  • Dosage is taken as per clinical prescription.
  • Any change in therapy should be undertaken with careful and appropriate monitoring since it may cause changes in glycaemic control.
  • The medicine may be taken with or without food.
  • The blood sugar needs to be checked often.
  • Low blood sugar (hypoglycaemia) may make a patient feel hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycaemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).
  • Signs of high blood sugar (hyperglycaemia), such as increased thirst or urination, should be taken care of.
  • On missing a dose, skip the dose and avoid taking two doses at a time.
  • On overdosing, seek emergency attention. Signs of overdosing include low blood pressure, extreme weakness, blurred vision, sweating, trouble speaking, tremors, stomach pain, confusion and seizure.
  • Stress, illness, surgery, exercise, alcohol use, or skipping meals may also affect blood sugar levels. The doctor may alter doses as per the condition.

Side Effects

  • Signs of an allergic reaction, hives, severe skin reaction (burning of the eyes, red or purple skin rash, blistering or peeling skin rash), symptoms of pancreatitis, severe pain in the upper stomach spreading to the back, with or without vomiting.
  • Severe or ongoing pain in your joints;
  • Little or no urination; or
  • Symptoms of heart failure–shortness of breath (even while lying down), swelling in your legs or feet, rapid weight gain.
  • Low blood sugar;
  • Headache; or
  • Runny or stuffy nose, sore throat.
  • Caution and safety of drug usage advised in pregnancy, lactation, paediatric use, geriatric use and renal implantation.


In the case of the following conditions, it is advisable to seek medical guidance before consuming the medication.

  • Kidney disease (or if you are on dialysis);
  • Heart problems;
