Proper Use

Drug information provided by: Merative, Micromedex®

No special preparations (for example, special diets, fasting, other medicines, laxatives, or enemas) are necessary before, during, or immediately after you take pyrvinium.

Use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.

Pinworms may be easily passed from one person to another, especially among persons in the same household. Therefore, all household members may have to be treated at the same time to prevent their infection or reinfection. Also, all household members may have to be treated again in 2 to 3 weeks to clear up the infection completely. Make sure each family member takes the correct amount, since the dose may be different for each person.

To help clear up your infection completely, take this medicine exactly as directed by your doctor. Read the instructions on the label and follow them carefully. The amount of medicine you need is based on your weight. You must take the exact amount if the medicine is going to work. A second course of pyrvinium is usually required to clear up the infection completely.
