My 16 Year Old Daughter Who Weighs 110 Pounds Took

My 16 year old daughter who weighs 110 pounds took a Midol Complete pill containing 500 mg of acetaminophen and a Tylenol containing 500 mg of Tylenol because she was having menstrual cramps. She now feels jittery and has stomach cramps. She also says her eyes hurt but she can see fine. I told her to eat some yogurt and she feels a little better. She has no skin issues such as a rash. Is this a significant problem and if so what should be done.
