What causes low blood pressure after taking metformin, and what should be done?

Metformin refers to metformin hydrochloride tablets. Low blood pressure after taking metformin hydrochloride tablets may be caused by malnutrition, improper use of medication, or drug side effects. Patients are advised to improve the condition through dietary adjustments and timely medical consultation. Specific analyses are as follows:

1. Malnutrition

In general, patients do not experience low blood pressure after taking metformin hydrochloride tablets. However, in individuals who already suffer from malnutrition, the medication might lead to low blood pressure in rare cases. If symptoms are not severe, patients can improve their condition by consuming more nutritious foods such as eggs, milk, and lean meat.

2. Improper Medication Use

Low blood pressure may also result from failure to strictly follow a doctor's instructions during medication use, or from combining metformin with other drugs, leading to inappropriate use. When necessary, patients may discontinue the medication. If low blood pressure persists, prompt medical attention is recommended, or alternative medications should be considered.

3. Drug Side Effects

Due to individual differences in physical constitution and varied responses to medication, some patients may experience side effects after taking the drug, such as low blood pressure, nausea, vomiting, and fatigue.

Besides the above reasons, low blood pressure could also be caused by factors such as fluid loss or excessive blood glucose control. Given the variety of potential causes, the specific reason may vary from person to person.
