Serious Feldene Side Effects
The U.S. Food and Drug Administration (FDA) warns that people using nonsteroidal anti-inflammatory drugs (
NSAIDs), including
Feldene, may have a higher risk of
heart attack or
stroke than those people who do not take NSAIDs. This warning does not apply to those who take aspirin. This risk may be higher in people who have been taking NSAIDs for a long time. These events can occur without any warning and can lead to loss of life. Get emergency medical help by calling 911 or an ambulance as soon as possible if you experience any of the following symptoms:
- Chest pain
- Shortness of breath
- Weakness on one side of your body
- Slurred speech.
Other serious side effects of Feldene include but are not limited to:
- Allergic reactions, such as:
- Swelling of the face or body
- Blisters
- Unexplained skin rash
- Wheezing
- Difficulty breathing
- Stomach or intestinal problems, including bleeding, ulcers, or a hole (known as a perforation)
- Liver damage, which can cause:
- Nausea
- Fatigue
- Yellowing of the skin or whites of the eyes (jaundice)
- Excessive tiredness
- Kidney problems, including kidney failure
- Fluid retention or unexplained weight gain
- Congestive heart failure
- Sensation that the pill is stuck in your throat.
Because Feldene can increase the risk of major or life-threatening bleeding, you should contact your doctor immediately if you notice any unusual bleeding or have any of the following symptoms:
- Bloody nose
- Black, tarry stools
- Blood in the urine or stools
- Vomiting blood
- Red or purple spots on the skin.
