Phenytoin is available in which forms?

• A. IV, Tablets, Chewable capsules, and Liquid forms
• B. IV only
• C. Tablets only
• D. Liquid forms only

Answer: (A)

Phenytoin is available in multiple dosage forms to fit different patient needs and clinical situations. The IV form is used for rapid control in emergencies or when a patient cannot take medications by mouth. Oral tablets provide ongoing maintenance therapy. Chewable tablets are especially helpful for children or others who have trouble swallowing capsules or tablets. Liquid forms (oral suspension) allow precise dosing and are useful for patients who can’t swallow pills or require dose adjustments. Because all these forms exist, the option that lists IV, tablets, chewable capsules, and liquid forms is the best answer.
