Why is Feldene prescribed?

To avoid digestive side effects, take Feldene with food or an antacid, and with a full glass of water. Never take it on an empty stomach.

--If you miss a dose...
If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take two doses at the same time.

Why should Feldene not be prescribed?
If you are sensitive to or have ever had an allergic reaction to Feldene, aspirin, or similar drugs, or if you have had asthma attacks caused by aspirin or other drugs of this type, you should not take Feldene. If you develop breathing difficulties or allergic symptoms after taking Feldene, seek emergency treatment immediately.
Special warnings about Feldene
The chances that Feldene will cause a stomach ulcer or bleeding are dramatically higher if you've had such problems previously. Severe stomach reactions are also more likely among older adults, those in poor health, smokers, heavy drinkers, and people taking steroids or blood thinners.
If you have heart disease, or high blood pressure, or other conditions that cause fluid retention, use Feldene with caution. Feldene can increase water retention.
Feldene has been known to damage the kidneys, and is not recommended for people with advanced kidney disease. Feldene can also cause liver damage. If you develop warning signs of liver dysfunction such as fatigue, itchiness, yellow skin or eyes, a flu-like feeling, and pain in the upper right abdomen, stop taking Feldene and see your doctor immediately.
Drugs such as Feldene may cause eye disturbances in some people. If you develop visual problems, notify your eye doctor.
