Things to Watch While Taking This Medicine

Managing diabetes successfully requires daily vigilance and regular health checkups with your care team.

  • Monitor Your Blood Sugar: Learn how to check your blood sugar levels at home. Understand the warning signs of low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia). Always keep fast-acting sugar sources, such as glucose tablets or hard candies, close by.
  • Watch for Serious Warning Signs: In rare cases, this medicine can cause a dangerous buildup of acid in the blood called lactic acid buildup. If you feel sick to your stomach, vomit, experience belly pain, feel extremely tired, or have trouble breathing, stop your medicine and call your doctor right away.
  • Surgery and Medical Scans: Tell your medical team that you take this medicine before having any surgery or imaging scans involving contrast dye. You may need to stop taking your pills temporarily.
  • Vitamin B12 Levels: Taking Metformin long-term can lower your body levels of vitamin B12 and folic acid. Talk to your doctor about eating a balanced diet or taking vitamin supplements if needed.

❓ FAQ

Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

What should I do if I experience mild stomach upset when taking this medicine?

Mild stomach upset and gas are common when starting Metformin. Taking your medicine with a larger meal can greatly reduce these symptoms. If the discomfort continues for more than a few weeks, talk to your doctor about your options.

Can I drink alcohol while taking Ertugliflozin and Metformin?

It is best to limit or avoid alcohol completely while taking this medicine. Alcohol can increase the risk of dangerous side effects, such as low blood sugar and lactic acid buildup. Always consult your doctor regarding safe alcohol limits.

Why does this medicine cause frequent urination?

The Ertugliflozin component works by helping your kidneys remove excess sugar from your body through your urine. This process naturally draws more water out, leading to increased urination and thirst. Make sure you stay well hydrated throughout the day.

Is it safe to exercise while taking these diabetes pills?

Yes, regular exercise is strongly encouraged for managing type 2 diabetes. However, physical activity can lower your blood sugar levels. Always monitor your blood sugar closely and keep fast-acting snacks nearby during your workouts.

What steps should I take if I am scheduled for medical imaging with contrast dye?

Tell your doctor and radiology team well in advance if you have an upcoming scan with contrast dye. You will likely need to stop taking your medicine temporarily before and after the procedure to protect your kidney health.
