Recommendations for People Considering a Metal-on-Metal Hip Implant
- Be aware that every hip implant has benefits and risks.
- Discuss your options for hip surgery with your orthopedic surgeon.
- See a list of questions6 to ask your orthopedic surgeon.
- If you are not having any symptoms and your orthopedic surgeon believes your implant is functioning properly, continue to follow-up routinely with the surgeon every one to two years.
- If you develop new or worsening problems, such as pain, swelling, numbness, noise (popping, grinding, clicking or squeaking of your hip) or a change in your ability to walk, contact your orthopedic surgeon right away.
- If you experience changes in your general health, including new or worsening symptoms outside your hip, let your doctor or other health care professional know you have a metal-on-metal hip implant.

The recommended doses of Intermezzo, a lower dose zolpidem product approved for middle-of-the-night awakenings, are not changing.
Risk: New data show that blood levels in some people who take zolpidem may be high enough the morning after use to impair activities that require alertness, including driving. This risk is highest for people who take products containing extended-release zolpidem (Ambien CR and generics). Women are especially vulnerable because zolpidem is cleared from the body more slowly in women than in men.
- Be aware that sleep drugs can cause impaired alertness the next morning, even if you feel fully awake.
- Talk to your health care professional about how to take the lowest effective dose of sleep drugs. Don’t assume that over-the-counter sleep medicines are necessarily safer alternatives to prescription drugs.

Super Power contains trace amounts of sildenafil, which is not listed on the label. Sildenafil is an active ingredient in an FDA-approved prescription drug used to treat erectile dysfunction, making Super Power an unapproved drug. The product was sold nationwide between August 2012 and January 2013.
Risk: Sildenafil may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol or heart disease often take nitrates.
- Immediately stop using the recalled product.
- Contact your health care professional if you have experienced any problems that may be related to taking this product. Signs of low blood pressure include dizziness, nausea, fainting, unusual thirst, blurred vision and fatigue. Sildenafil may also cause side effects such as headaches and flushing of the face.
