  3. If you miss a dose, take it as soon as you remember, unless it’s close to your next dose—then skip the missed one. 

How Metformin Works

Metformin helps lower blood sugar levels in three ways: it reduces the amount of sugar your liver makes, lowers how much sugar your body absorbs from food, and makes your body more responsive to insulin. This helps control both fasting and after-meal blood sugar levels. 

In PCOS, metformin lowers insulin levels, which also reduces certain hormones like luteinizing hormone and androgens. This helps balance hormones and regulate the menstrual cycle in women. 

Safety Measures and Warning

1- Allergy/Hypersensitivity

If you ever had an allergy to metformin, inform your doctor immediately.

2- Kidney Disease

Since metformin is excreted out of the body through the kidney, patients with pre-existing kidney disease should inform their doctor before taking the medication. The medication should not be prescribed to patients 80 years of age.

3- Metabolic Acidosis

If your body produces too much acid in a short period of time, a condition known as metabolic acidosis, inform your doctor, as metformin is not recommended for patients with this condition.

Metformin Interaction With Other Medicines

Avoid taking metformin 850 mg with the following medicines, as it may increase or decrease the desired effect, or in worse cases, it could be fatal: 

Metformin Interaction With Food Products

Avoid consuming alcohol and tobacco with metformin as alcohol increases the risk of lactic acidosis (building up of lactic acid in the bloodstream).  

Storage

  1. The medicine should be stored at room temperature 
  2. Keep away from sunlight and moisture 
  3. Keep away from the reach of children 

Metformin Chemical Structure

IUPAC (International Union of Pure and Applied Chemistry)/ Chemical name- 

3-(diaminomethylidene)-1,1-dimethylguanidine. 

Intake Routine/Cycle

Daily Dose

Take metformin exactly as your doctor recommends. The dose may change based on your condition and how well you respond. Do not take more than prescribed without consulting your doctor.

Missed Dose

If you forget to take your medicine, take the medication soon as you remember. If it’s nearly time for your next dose, skip the missed one and continue with your regular schedule. Always consult the doctor before making any changes to your dosage.

Overdose

If you know someone taking metformin who experiences symptoms like tiredness, weakness, vomiting, nausea, or rapid breathing, rush them to the hospital immediately, as they may have knowingly or unknowingly taken more than the required dose.

Dietary and Lifestyle Management

Diabetes cannot be cured permanently, but with a healthy lifestyle and exercise, it can be managed easily. Diabetic patients are advised to monitor their blood sugar level before and after meals. Following are the natural ways to manage blood sugar levels:  

1- Food

Eating healthy is important for managing diabetes. Carbohydrates have a huge impact on our blood sugar level, as they break into sugar (glucose), which is poison for diabetic patients as they already have elevated blood sugar levels. Therefore, a diabetic patient needs to count the amount of carbohydrates he is taking. 

2- Do Exercise

Exercise plays an important role in managing diabetes. When our body moves and gets active, the muscles use blood sugar for energy, resulting in a low amount of sugar in our bloodstream. Adults are advised to exercise for at least 150 minutes a week. 

3- Medicine

Take your medicine on time, as it is designed to lower blood sugar levels. 

4- Avoid Alcohol

Consumptions of alcohol while on therapy with metformin increase the risk of lactic acidosis, that is, lactic acid increases in the bloodstream. Lactic acid can cause symptoms like muscle pain, difficulty breathing, stomach pain, and weakness. Alcohol also decreases the level of blood sugar. It is generally recommended to avoid alcohol while on glimepiride.

FAQ’s

1- Can metformin cause weight loss? 

Yes, metformin can cause a 2%-3% loss of body weight within the first year of starting the medicine. 

2- How much metformin can be taken in a day? 

The daily dose limit for metformin is 2,000 mg. This means you can take 4 tablets of 500 mg or 2 tablets of 1,000 mg per day, as instructed by your doctor. 

3- Can metformin cause diarrhea? 

Yes, one of the side effects of metformin is diarrhea. 

4- Why is metformin used for PCOS? 

In PCOS, there is a significant hormone imbalance that leads to the formation of cysts in the uterus. Metformin helps restore hormonal balance in the body and triggers ovulation, making it an effective treatment for PCOS. 

5- Can metformin cause hair loss? 

Yes, metformin is associated with hair loss. Long-term use of metformin can lead to vitamin B12 deficiency and anemia, which may cause symptoms like hair fall.
