Objectives

The increase in pharmaceutical drug consumption and the presence of these drugs in the environment causes concern about their effects. Due to the prevalence of metformin in surface and waste waters, this study investigated its 7 day chronic toxicity. Typically, metformin is prescribed with other medications to control blood sugar levels and achieve healthy HbA1c (hemoglobin) levels for people with type 2 diabetes (T2D).

Methods

Accordingly, the effect of metformin on catfish (Clarias gariepinus) following exposure and post-exposure recovery was evaluated using blood indices as biomarkers for hematotoxicity, electrolytes imbalance, oxidative stress, and immunosuppression. The first group was a control group, the second group was exposed to 10 mg/L of metformin, and the third group was exposed to 50 mg/L of metformin for 7 days, followed by a 15-day recovery period. Hemotoxic effects of the …
