What is the pregnancy category for Chlorthalidone?

Chlorthalidone is classified under pregnancy category C. This indicates that animal reproduction studies have shown an adverse effect on the fetus, but there are no adequate and well-controlled studies in humans. Drugs in category C may be given to a pregnant woman if the potential benefits justify the potential risks to the fetus. Since Chlorthalidone does indeed have a pregnancy category, the indication that it falls under 'None' would be incorrect. The appropriate context for determining the medication's use during pregnancy includes evaluating the balance of risks and benefits, which is essential for clinical decision-making regarding medications in this group.
