If your little boy has swallowed a Bipilac tablet by mistake, don't panic. The most frequent symptoms of ingestion are upset stomach and perhaps some vomiting or diarrhea. The reason for this is that the stomach doesn’t like the pill. To make him feel better, make sure he drinks plenty of water and keep an eye on him constantly. It’s important to observe any strange behavior in your child and if there is any, call your local poison control centre at once.
