Which medications' timing should be considered with dialysis because they may be removed during treatment?

• A. Some vaccines.
• B. Some antibiotics and antihypertensives.
• C. Iron supplements.
• D. Vitamins.

Answer: (B)

Dialysis can pull certain medications out of the bloodstream during treatment. The meds most affected are those that are small, water-soluble, and not highly bound to proteins, which lets the dialysis membrane clear them effectively. Because of this, the timing of administration around a dialysis session matters: if given before dialysis, the drug may be removed too quickly and not provide full effect, or a follow-up dose after dialysis may be needed to keep levels therapeutic. Antibiotics and some antihypertensives are often dialyzable, so their dosing schedule is adjusted in relation to dialysis to maintain proper blood levels and blood pressure control. Vaccines, iron supplements, and vitamins generally aren’t removed in the same way by dialysis, so their timing around sessions isn’t typically a concern.
