Let's learn about the diabetes medications Canagliflozin and Metformin.

Do you have diabetes, or Type 2 Diabetes? Or does someone you know have this condition? Then your doctor may have prescribed you a combination of two drugs, namely Canagliflozin and Metformin, specifically an extended-release pill. The brand name of this may be Invokamet XR. So, let's talk a little more about this drug today, shall we?

What really happens with this medicine?

Simply put, this medicine is used to control your blood sugar levels (blood glucose) . When you have `Type 2 Diabetes`, there are some changes in the way our body controls sugar. This medicine works by lowering that sugar level and helping you stay healthy. In this, `Canagliflozin` helps the body excrete excess sugar through the urine, while `Metformin` reduces the production of sugar by the liver and increases the sensitivity of the body's cells to insulin. But remember, this medicine alone is not enough. Good diet and exercise are also very important for this.

What are the things you need to tell your doctor before taking this medicine?

This is very important. If you have any of the following conditions, you should definitely tell your doctor before starting this medicine. Because, only then can the doctor decide whether this medicine is suitable for you or not, or whether the dosage needs to be changed. Just think, if you do not tell the doctor these details, you may face unnecessary trouble.

• If you have `Anemia`
• If you have artery disease

When using this medicine, you need to be a little more careful about your health.

• See your doctor regularly (`regular checks`) to monitor your condition . Get tests like kidney function and vitamin B12 levels as your doctor recommends.
• Because this medicine contains `Metformin`, sometimes the acidity of the blood can become dangerously high (`Lactic Acidosis`) . Although this is very rare, it can be very dangerous if it happens. If you experience symptoms such as nausea, vomiting, stomach pain, unusual tiredness, difficulty breathing, rapid breathing, feeling cold, or dizziness, stop taking this medicine immediately and call your doctor or go to a hospital . If possible, also check your urine for ketones with a `ketone dipstick`.

Symptoms include excessive thirst, frequent urination, dry mouth, fatigue, fruity breath odor, shortness of breath, stomach pain, nausea, and vomiting. If you experience any of these symptoms, tell your doctor immediately.
• Your doctor will often order a test called `HbA1C (A1C)` to see how well your blood sugar is being controlled . This is a simple blood test. It can show how well your blood sugar has been controlled over a period of 2-3 months. This test is usually done every 3-6 months.
• Learn how to test your blood sugar levels at home . Also, be aware of the symptoms of low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) and how to manage them .
• Always keep a quick source of sugar (e.g., sugar cubes, glucose tablets, a sugary drink, fruit juice) with you in case you experience symptoms of low blood sugar (sweating, shaking, extreme hunger, rapid heartbeat, dizziness, confusion). However, if you become unconscious or have seizures , tell your family members that they may choke if they try to give you food or drink. If this happens , you should seek immediate medical attention .
• This medicine may lower your folic acid and vitamin B12 levels, especially with metformin. Therefore, make sure you eat enough vitamins while taking this medicine. Your doctor may prescribe a vitamin supplement if necessary.
• Avoid dehydration . Drink plenty of water, especially in hot weather, when exercising, or if you have a stomachache.
