Birth Control Pills and Toddlers

The Bottom Line

Packages of birth control pills contain hormone pills and may contain iron and placebo pills. Children who swallow birth control hormones are not at risk, even if they are boys. There are few, if any short term effects from the hormones. Children who swallow birth control hormones may have stomach upset, diarrhea, or irritability but no long-term effects.

The Full Story

Worried parents often call Poison Control about small children who swallowed birth control pills. Some of these parents panic – especially if the toddler is a little boy. Usually, they are surprised to learn that swallowing birth control pills is NOT dangerous for children. There are no long-term effects and few, if any, short-term effects. 

Many women take birth control pills, also called oral contraceptives. They are prescribed for several reasons besides preventing pregnancy: very heavy menstrual periods, severe menstrual cramps, polycystic ovary syndrome, endometriosis, some hormonal imbalances, and acne.

Because birth control pills are widely prescribed, they are widely available – and that means toddlers can find them in bathrooms, bedrooms, kitchens, purses, and backpacks. Children learn by imitating adults; children who watch mom taking pills want to take those pills, too.

Birth control pills are available as brand-name drugs and generic drugs. They contain the female hormones estrogen and progesterone. The exact type of hormone and the amount vary from brand to brand. 

Most types of birth control pills come in packages of twenty-eight pills.

  • Twenty-one pills contain hormones, the active ingredients.
  • Seven pills are placebo, or "dummy" pills. These do NOT contain hormones. In some cases, they contain iron; iron can be a problem for children who swallow too much.

Children who swallow hormone pills are not in danger. The medicine is absorbed quickly and is quickly eliminated from the body. There are no long term effects in girls OR boys.

There could be some minor short-term effects. Some children have a bit of stomach upset. A few children have some diarrhea or irritability. These symptoms go away without treatment. At one time, it was thought that little girls might have slight vaginal bleeding a few days after swallowing birth control hormones. This is unlikely because today's birth control pills contain such low doses of hormones. In any case, this would be a slight, one-time event.

Sometimes children swallow the iron pills in birth control packages. Poison Control will calculate the total amount of iron the child swallowed and compare it to the child's body weight. If any treatment is needed, Poison Control will recommend it. There is no danger in swallowing placebo pills that do not contain iron.

If a child swallows birth control pills, use the webPOISONCONTROL® online tool for guidance or call Poison Control right away at 1-800-222-1222. Take the package to the computer or phone. You will be asked for the exact brand name of the medicine and how many pills are missing. If iron is involved, you will be asked for your child's weight. It's unlikely that treatment will be needed, but Poison Control will tell you if there's anything at all you need to do.

For More Information

Iron poisoning from birth control pills rarely if ever happens. Iron is very poisonous to children in high doses, though. If you suspect that a child has swallowed iron pills or vitamins with iron, call Poison Control right away at 1-800-222-1222.

Prevention Tips

Like all medicines, birth control pills should be locked up out of sight and reach of children.

This Really Happened

Case 1: A 2-year-old girl ate two of her mom's birth control pills. Her mom called Poison Control and was reassured that no problem was expected. The following day Poison Control placed a follow up call and the child's mom reported that she had no bad effects. 

Case 2: A 3-year-old boy ate two of his mom's birth control pills late one evening. They contained iron. Based on his weight and the amount of iron in each pill, Poison Control determined that no bad effects would be expected other than possible mild stomach upset. The child vomited once early the following morning but was fine after that.
