Is Toilet Paper Bad For You? Here’s What Experts Say

“When they switch to plain, unbleached, fragrance-free options, the irritation usually clears quickly,” she says.

Dr. Meagan W. Shepherd, an allergist and immunologist based in Barboursville, West Virginia, says people are often surprised to learn how commonly allergens are found in toilet paper, noting that both traditional paper and flushable wipes can cause irritation.

“Wet varieties such as flushable wipes often have preservatives like methylchloroisothiazolinone and methylisothiozolinone, which together account for about 10% of contact allergen sensitizations in North America,” says Shepherd. Dry varieties, on the other hand, are more likely to include added fragrances or dyes, which can act as irritants or allergic triggers, she says.

“I frequently see patients with severe vulvar rashes caused by hidden chemicals,” she adds.

Shepherd also says that if people are struggling to find toilet paper they can tolerate, she recommends skipping recycled paper. “It can be rougher than regular varieties, leading to irritation,” she says. “Plus, trace amounts of various allergens found in the original paper product sources could still be present and potentially cause a reaction in those who are sensitized.”
