Glucotrust Side Effects: Understanding the Potential Risks


When it comes to managing diabetes, many individuals turn to medications like Glucotrust to help regulate blood sugar levels. Glucotrust, also known as metformin, is a commonly prescribed medication that can be highly effective in controlling diabetes. However, like any medication, Glucotrust does come with potential side effects that individuals should be aware of. In this blog post, we will explore the various side effects associated with Glucotrust and provide you with the information you need to make informed decisions about your diabetes management.

1. Gastrointestinal Disturbances:

One of the most commonly reported side effects of Glucotrust is gastrointestinal disturbances. This can include symptoms such as nausea, vomiting, diarrhea, and abdominal pain. These side effects are typically mild and transient, meaning they tend to go away on their own after a short period of time. However, for some individuals, these gastrointestinal disturbances can be severe and persistent, leading to discomfort and a decreased quality of life. If you experience any of these symptoms, it is important to speak with your healthcare provider to determine the best course of action.

2. Vitamin B12 Deficiency:

Another potential side effect of long-term Glucotrust use is a vitamin B12 deficiency. Vitamin B12 is essential for the production of red blood cells and the proper functioning of the nervous system. Studies have shown that metformin can interfere with the absorption of vitamin B12 in the body, leading to a deficiency over time. Symptoms of a vitamin B12 deficiency can include fatigue, weakness, numbness or tingling in the hands and feet, and difficulty walking. It is recommended that individuals taking Glucotrust have their vitamin B12 levels monitored regularly and consider supplementation if necessary.

3. Lactic Acidosis:

Although rare, lactic acidosis is a serious side effect that can occur with Glucotrust use. Lactic acidosis is a buildup of lactic acid in the blood, which can be life-threatening if left untreated. Symptoms of lactic acidosis can include rapid breathing, muscle pain, weakness, and a general feeling of unwellness. If you experience any of these symptoms while taking Glucotrust, it is crucial to seek immediate medical attention. It is important to note that the risk of lactic acidosis is higher in individuals with kidney or liver impairment, as well as those who consume excessive alcohol.

4. Hypoglycemia:

Glucotrust works by lowering blood sugar levels, and as a result, there is a risk of hypoglycemia, or low blood sugar. Hypoglycemia can cause symptoms such as dizziness, confusion, sweating, and shakiness. It is important for individuals taking Glucotrust to monitor their blood sugar levels regularly and be aware of the signs and symptoms of hypoglycemia. If you experience low blood sugar, it is recommended to consume a source of quick-acting carbohydrates, such as fruit juice or glucose tablets, to raise your blood sugar levels back to normal.

5. Other Considerations:

In addition to the side effects mentioned above, it is important to consider other potential interactions and contraindications with Glucotrust. For example, certain medications, such as cimetidine and beta-blockers, can interact with Glucotrust and affect its effectiveness or increase the risk of side effects. It is crucial to inform your healthcare provider about all medications, supplements, and herbal remedies you are taking to ensure there are no potential interactions. Additionally, Glucotrust is not recommended for individuals with certain medical conditions, such as kidney or liver disease, heart failure, or a history of alcohol abuse.


Glucotrust can be a valuable tool in managing diabetes and controlling blood sugar levels. However, it is important to be aware of the potential side effects associated with this medication. Gastrointestinal disturbances, vitamin B12 deficiency, lactic acidosis, hypoglycemia, and other considerations should be taken into account when using Glucotrust. By staying informed and working closely with your healthcare provider, you can minimize the risks and maximize the benefits of Glucotrust in your diabetes management plan.
