What should I watch for while using this medicine?

Visit your doctor or health care professional to check that your infection has gone. If you have a severe infection you may need a second course of tablets.

Wash your hands, scrub your fingernails and shower often. Every day change and launder bedclothes, linens, and undergarments. This will help keep other family members from getting infected. Disinfect the toilet every day, and damp mop the floors often to reduce the number of worm eggs.

Other people in your house may need treatment. Check with your doctor or health care professional as some worms are spread easily. Treat cats and dogs regularly for worms.

You may get dizzy. Until you know how this medicine affects you, do not drive, use machinery, or do anything that needs mental alertness.
