(proe pox' i feen)
[Posted 7/7/2009] FDA notified healthcare professionals that it is taking several actions to reduce the risk of overdose in patients using pain medications that contain propoxyphene because of data linking propoxyphene and fatal overdoses. The agency will require manufacturers of propoxyphene-containing products to strengthen the label, including the boxed warning, emphasizing the potential for overdose when using these products and to provide a medication guide to patients stressing the importance of using the drugs as directed.
FDA is requiring a new safety study assessing unanswered questions about the effects of propoxyphene on the heart at higher than recommended doses. Findings from this study, as well as other data, could lead to additional regulatory action. To further evaluate the safety of propoxyphene, FDA plans to work with several groups including the Centers for Medicare & Medicaid Services and the Veterans Health Administration to study how often the elderly are prescribed propoxyphene instead of other pain relievers and the difference in the safety profiles of propoxyphene compared to other drugs. For more information visit the FDA website at: http://www.fda.gov/Safety/MedWatch/SafetyInformation and http://www.fda.gov/Drugs/DrugSafety.
Propoxyphene in high doses, taken by itself or in combination with other drugs, has been associated with drug-related deaths. Do not take propoxyphene in combination with other drugs that cause drowsiness: alcohol, tranquilizers, sleep aids, antidepressant drugs, or antihistamines. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Propoxyphene comes as a tablet, capsule, and liquid to take by mouth. It usually is taken every 4 hours as needed. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take propoxyphene exactly as directed.
Propoxyphene can be habit-forming.
Shake the liquid well before each use.
Before taking propoxyphene,
tell your doctor and pharmacist if you are allergic to propoxyphene or any other drugs.
tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other pain relievers; anticoagulants ('blood-thinners') such as warfarin (Coumadin); antidepressants; antihistamines; medications for cough, cold, or allergies; muscle relaxants; sedatives; seizure medications; sleeping pills; tranquilizers; and vitamins.
tell your doctor if you have or have ever had liver or kidney disease, or a history of alcoholism.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking propoxyphene, call your doctor.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking propoxyphene.
you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
remember that alcohol can add to the drowsiness caused by this drug.
Propoxyphene usually is taken as needed. If your doctor has told you to take propoxyphene regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Propoxyphene may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
dizziness
lightheadedness
drowsiness
upset stomach
vomiting
constipation
stomach pain
skin rash
mood changes
headache
If you experience the following symptom, call your doctor immediately:
difficulty breathing
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at http://www.fda.gov/Safety/MedWatch] or by phone [1-800-332-1088].
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).
