What Does This Medicine Actually Do?

Simply put, this medicine helps lower the amount of sugar, or glucose, in your blood. It contains two different active drugs working together in one single tablet to help your body manage sugar better.

The first active drug is Empagliflozin. This drug works mainly in your kidneys. It helps your body get rid of extra sugar through your urine so that less sugar stays in your bloodstream.

The second active drug is Metformin. This drug lowers the amount of sugar your liver makes. It also helps the cells in your body respond much better to your natural insulin.

The most important thing to remember is that this medicine works best alongside a healthy meal plan and regular physical exercise. Taking pills alone is not enough. You must also build healthy daily habits.

Things to Tell Your Doctor Before Starting This Medicine

Before you take your very first dose, sharing your full health history with your doctor is extremely important. If any of the following health conditions apply to you, let your doctor know right away.

Information Category Detailed Description
Existing Medical Conditions Kidney disease, liver disease, heart problems, high cholesterol, anemia, low blood pressure, pancreas problems, polycystic ovary syndrome, or Type 1 diabetes.
Infections and Other Issues Frequent urinary tract infections, a history of genital yeast infections, trouble passing urine, or severe open wounds and infections.
Lifestyle and Diet Regular alcohol use, following a strict low-salt diet, eating less food due to illness or surgery, frequent vomiting, or suffering from body dehydration.
Special Situations Pregnancy, trying to get pregnant, breastfeeding, upcoming surgeries or medical tests, or any known allergies to foods or medicines.

How to Use This Medicine Correctly

Following simple daily rules ensures your medicine works safely and effectively in your body every single day.

  • Take your tablet with a full glass of water.
  • Swallow the tablet completely whole. Never crush, chew, split, or break the pill. These tablets use an extended-release design, meaning the medicine enters your body slowly over many hours. Breaking the pill releases all the medicine at once, which can cause dangerous side effects.
  • Take this medicine right along with a meal to protect your stomach.
  • Take your dose at the exact same time every day as directed by your doctor. Never stop taking your medicine without consulting your doctor.

What to Do If You Take Too Much Medicine

If you believe you took more medicine than your doctor prescribed, take action right away. Call your local emergency services or go to the nearest emergency department right away for professional medical evaluation.

What to Do If You Miss a Dose

If you forget to take your scheduled dose, take it as soon as you remember. However, if it is almost time for your next regular dose, skip the missed pill entirely. Never take two doses at the same time to make up for a missed pill.

Other Medicines That May Intersect With This Drug

Sharing a complete list of every medicine, vitamin, herbal product, and supplement you take with your doctor is vital. Certain products can interact poorly with your diabetes tablets.

In particular, you must avoid certain contrast dye injections used during X-rays, CT scans, or MRI procedures unless your doctor gives explicit instructions. You should also avoid taking a medicine called Dofetilide.

Bring a written list of all your current medicines to every doctor visit. Over-the-counter cough syrups can sometimes contain hidden sugars or alcohol that disrupt your blood sugar levels.

Things to Watch Closely While Taking This Medicine

  • Lactic Acidosis: This is a rare but serious medical condition. If you experience severe nausea, vomiting, belly pain, extreme tiredness, or trouble breathing, stop taking the medicine and call your doctor right away.
  • Diabetic Ketoacidosis: This is another serious condition. Watch for a dry mouth, extreme thirst, frequent urination, a fruity smell on your breath, or breathing difficulties. Get medical help right away if these occur.
  • HbA1C Blood Tests: Attend your scheduled blood tests every two to three months so your doctor can check your long-term blood sugar control.
  • Monitoring Blood Sugar: Learn the warning signs of both low blood sugar and high blood sugar. Keep fast-acting sugar sources like glucose tablets nearby in case your blood sugar drops too low.
  • Surgeries and Medical Scans: If you have an upcoming surgery or an imaging scan requiring contrast dye, inform your medical team beforehand. You may need to stop taking your pills temporarily.
  • Pregnancy Planning: This medicine can increase your chances of becoming pregnant unexpectedly. Talk with your doctor about effective birth control options. If you become pregnant, notify your doctor right away.
  • Vitamin Deficiencies: Long-term use of this medicine can lower your vitamin B12 and folic acid levels. Eat a balanced diet and talk to your doctor about whether you need vitamin supplements.

How to Store Your Medicine Safely

  • Keep all your medicines safely stored away in a locked cabinet where children and pets cannot reach them.
  • Store your tablets at normal room temperature, ideally between 15°C and 30°C (59°F to 86°F), away from excess moisture and heat.
  • Safely dispose of any expired or unused medicines through local pharmacy take-back programs rather than throwing them in household trash.

💡 Take-Home Message

❓ FAQ

Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

Can I split my Empagliflozin and Metformin extended-release tablet in half?

No, you should never split, crush, or chew these tablets. They are specially designed to release medicine slowly over time. Splitting them ruins this special design and can release too much medicine into your body at once.

What should I do if I experience mild stomach upset when starting this pill?

Mild stomach upset is common when first taking Metformin. Taking your medicine right along with a substantial meal usually helps reduce stomach discomfort. If the upset does not go away after a week, talk to your doctor.

Why does Empagliflozin cause me to urinate more often?

Empagliflozin works by helping your kidneys remove excess sugar from your body through your urine. Because it pulls extra sugar out, it also draws extra water along with it, leading to more frequent trips to the bathroom.

Is it safe to drink alcohol while taking this diabetes medicine?

Drinking alcohol while taking Metformin can greatly increase your risk of developing a dangerous condition called lactic acidosis. It is best to limit or completely avoid alcohol and discuss your drinking habits openly with your doctor.

How often will I need blood tests while taking this medicine?

Your doctor will usually check your kidney function and your HbA1c levels every three to six months. These routine blood tests ensure your medicine continues working safely and effectively for your body.
