What Kind of Medicine Is Sitagliptin?
Put simply, Sitagliptin is a prescription medicine used to treat adults with type 2 diabetes. The way this medicine works inside your body is quite fascinating. Its main job is to help boost your body's natural insulin levels after you eat a meal, which helps lower the amount of sugar floating in your bloodstream. At the same time, it tells your liver to stop releasing extra sugar into your blood.
However, it is vital to remember that taking this medicine alone is not enough. You get the best possible health results when you combine your daily tablets with a balanced, healthy diet and regular physical exercise.
Medicine is only one piece of the puzzle. Your daily food choices and staying physically active work hand in hand with Sitagliptin to keep your blood sugar in a healthy, safe range.
Important Things to Tell Your Doctor Before Starting
Before you take your very first dose of Sitagliptin, you need to share your complete medical history with your doctor. Never hide any health details, because sharing this information is essential for keeping you safe.
- Diabetic ketoacidosis: Tell your doctor if you have ever had this dangerous diabetes complication.
- Kidney disease: This is exceptionally important because your doctor may need to lower your medicine dose based on how well your kidneys are filtering.
- History of pancreatitis: Let your doctor know if you have ever suffered from inflammation of your pancreas.
- Severe allergic reactions: Inform your doctor if past medicines ever caused swelling of your tongue, face, or lips, trouble breathing, trouble swallowing, or voice changes.
- Type 1 diabetes: Sitagliptin is meant exclusively for type 2 diabetes and is not suitable if you have type 1 diabetes.
- Allergies: Mention any known allergies to Sitagliptin, other drugs, foods, or artificial dyes.
- Pregnancy and breastfeeding: Tell your doctor if you are pregnant, planning to become pregnant, or currently nursing a baby.

Taking your medicine properly is very straightforward. Simply swallow your tablet whole with a refreshing glass of water. You can take your pill either before you eat a meal or after you eat, depending on your personal preference. Always follow the exact schedule your doctor gave you.
Here are a few crucial rules to keep in mind:
- Never crush, chew, or break the tablet. Swallow the pill completely whole every time.
- Try to take your medicine at the exact same time every day so you do not forget a dose.
- Never stop taking your medicine unless your doctor specifically tells you it is safe to do so.
- This prescription is tailored specifically for you. Never share your pills with anyone else.
What If You Miss a Dose?
If you accidentally forget to take your medicine at the normal time, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed pill entirely and take your next dose at the regular time. Never take two doses at the exact same time to make up for a missed pill.
What If You Take Too Much?
If you think you have taken more medicine than your doctor prescribed, you must act quickly. Go right away to the nearest hospital emergency department (ER / A&E). In the UK, call 999 or go to your nearest hospital. In the US, call 911 right away.
Things to Watch While Taking This Medicine
To make sure your treatment plan is working properly, you need to attend all your scheduled checkups with your doctor.
- HbA1c blood test: Your doctor will order a special blood test called an HbA1c test. This test shows your average blood sugar control over the past two to three months. You will likely need this test every three to six months.
- Home blood sugar monitoring: Learning how to check your blood sugar at home is a very smart habit. You must also learn the warning signs of low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) so you know how to respond.
- Handling low blood sugar: Always keep fast-acting sugar nearby, such as glucose tablets, hard candies, or a sugary drink. However, remember that if someone is having a seizure or loses consciousness from severe low blood sugar, never put anything in their mouth because they could choke. Get emergency medical help right away.
- Other daily habits: If you get sick with an illness or exercise much harder than normal, talk to your doctor to see if your dose needs adjusting. Do not skip meals, and talk openly with your doctor about drinking alcohol.
- Medical identification: Wearing a medical alert bracelet or carrying a card in your wallet that states you have diabetes and list your medicines is a very wise practice.
