Almost every week, the FDA removes tainted dietary supplements from the market due to health concerns. For example, in January 2016, the FDA issued an alert about “Pink Bikini and Shorts on the Beach Capsules” from Lucy's Weight Loss System of Arlington, TX. It was found that these weight loss aids contained sibutramine, phenolphthalein, and/or diclofenac, but these ingredients were not declared on the label. Sibutramine can cause increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. Phenolphthalein was previously used in over-the-counter (OTC) laxatives, but was removed from the US market. Health risks linked to phenolphthalein could include potentially serious stomach upset, irregular heartbeat, and cancer with long-term use. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) which could lead to serious side effects in patients taking other NSAIDs, with recent heart surgery, or with allergies to NSAIDs. NSAIDs can also lead to stomach bleeding, fatal heart attack or stroke.
To prevent nausea and vomiting, you can take the non-prescription anti-nausea medicine meclizine (also sold under the brand names Dramamine II or Bonine ). Research shows that taking two 25 mg tablets 1 hour before using combined emergency contraceptive pills reduces the risk of nausea by 27% and vomiting by 64%, but this drug doubles your chances of feeling drowsy (to about 30%). If you happen to throw up within 1 hour of taking a dose of either type of emergency contraceptive pills, some health care providers recommend repeating that dose just in case your body didn’t have a chance to absorb all of the medication.
