HOW should this medicine be used?
Diethylpropion comes as a regular and extended-release (long-acting) tablet. Diethylpropion usually is taken three times a day, 1 hour before meals (regular tablets), or once a day in midmorning (extended-release tablets). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take diethylpropion exactly as directed.
Do not crush, chew, or cut extended-release tablets; swallow them whole.
Diethylpropion may be habit-forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to. Call your doctor if diethylpropion loses its effect.

Tell your doctor if you have taken other diet pills in the past year.

What SPECIAL DIETARY instructions should I follow?

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
What should I do in case of OVERDOSE?
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at Web Site. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
What OTHER INFORMATION should I know?
Keep all appointments with your doctor. Your doctor may order certain tests to check your response to diethylpropion.
Diethylpropion may affect blood sugar levels of diabetic patients and may cover up some signs and symptoms of hypoglycemia (low blood sugar). If you notice a change in the results of your urine or blood sugar tests, check with your doctor.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
