The most common side effect with taking too much Pepto-Bismol is the temporary and harmless black darkening of the tongue and stools. This can subside and is caused by a reaction to sulfa in the mouth.

However, there are more serious side effects with toxic levels of Pepto-Bismol, such as severe allergic reactions (rash, hive, itching, difficulty breathing, tightness in chest, swelling of the mouth, face, lips, or tongue), fever, hearing loss, nausea, ringing in the ears, severe constipation, and vomiting.

If any of these symptoms do occur, stop taking the medication and consult your health care professional.
