What over-the-counter medications are available to help lose weight?

None sorry. Try this. Make sure you exercise at least 30 minutes a day, don't skip meals, avoid soda, juice, dairy, alcohol and fried foods. Eat a healthy well balanced diet! Also water, organic vegetable broth, green leafy vegetables, natural pickles, apples are great to fill you up so you dont feel hungry and they are very low in calories.
None. None of the over-the-counter products that claim to promote weight loss have been shown to be effective. Adjusting the portions of what you are eating, and starting a regular exercise program will help you lose weight.
