The medication Feldene is also referred to as piroxicam and is used to cure symptoms of osteoarthritis and rheumatoid arthritis, including reducing swelling and treating pain.

Some doctors may also prescribe it to relieve pain caused by other conditions. It is particularly important to consult your doctor before using Feldene to cure pain resulting from chronic conditions to avoid side effects.

How Does Feldene Work?

Feldene works by inhibiting the enzyme cyclooxygenases (COX), which plays a vital role in producing prostaglandins. Prostaglandins are responsible for several body responses including fever, pain, and inflammation. There are two types of COX namely:

  • COX-1: It is mostly found in body tissues in the gastrointestinal tract. COX-1’s main role is to maintain and protect the lining of the stomach and intestines from digestive juices.
  • COX-2: Majorly concerned with inflammation, pain, and fever.

When Feldene blocks the COX enzyme, it reduces the production of prostaglandins in the body hence an overall reduction in inflammation, pain, and fever.

Forms of Feldene

Feldene is available in two forms for easy administration. These include:

Tablets

The medication is taken orally to reduce pain and inflammation in conditions like arthritis. Feldene capsules come in different strengths, namely:

  • 10 mg maroon and blue capsule
  • 20 mg maroon capsule

It is advisable to start with the lowest effective dosage and adjust the dosage based on individual needs and as prescribed by your doctor.

Gel

Feldene is also available as a clear, pale yellow gel. The gel comes in 25-gram or 50-gram tubes.

Ideally, Feldene 0.5% gel is applied directly to affected areas to relieve pain and inflammation that may have been caused by sprains. The skin on the affected area should be healthy with no open wounds, rashes, or infections.

Precautions and Warnings of Feldene

Patients using Feldene should be mindful of the precautions and warnings associated with the medication. If not used appropriately, Feldene can cause serious health risks. Here are precautions and warnings to note:

  • Skin Reactions: Patients using Feldene gel, should be monitored closely for any skin reactions after applying the medicine, as it can cause progressive skin rash often accompanied by blisters or mucosal lesions. In case of any skin reaction, Feldene should be discontinued immediately.

  • Pregnancy and Lactation: Avoid using Feldene if you are pregnant or planning to get pregnant because it can increase the risk of spontaneous abortion during the first two trimesters of pregnancy. Feldene may also pass to the breast milk, causing risks to nursing infants.
  • Gastrointestinal Risks: Using Feldene may increase the risk of a patient having serious gastrointestinal diseases such as ulcers, bleeding, and perforations. As such, patients having a medical history of gastrointestinal issues should use the medication with caution.
  • Cardiovascular Diseases: Feldene may increase the risk of developing cardiovascular diseases such as stroke and heart attack, especially in patients with pre-existing cardiovascular conditions.
  • Hypertension: The use of Feldene can result in a new development of blood pressure or exacerbation of existing blood pressure. Both scenarios can lead to an increased risk of cardiovascular diseases.
  • Elderly people: Elderly patients are most vulnerable to developing adverse effects of the drug like bleeding, hypertension, and cardiovascular disease. Therefore, they should be monitored closely while using the medication.

Interactions With Feldene

Feldene can interact with different medications which can prevent the effectiveness of the drug. Certain interactions can also lead to potential side effects like hypertension, ulcers, and bleeding.

Drug Interaction
Anticoagulants e.g., Warfarin Concurrent use of anticoagulants and Feldene can cause enhanced bleeding and gastrointestinal ulceration.
Lithium The interaction of Feldene and lithium decreases renal clearance. This increases lithium concentrations in blood leading to lithium toxicity, which also affects the central nervous system.
Alcohol Combining alcohol with Feldene results in an increased risk of central nervous system depression, which causes gastrointestinal irritation and increases the risk of bleeding.
Diuretics Causes reduced blood pressure control and compromised diuretic efficacy.
Cardiac glycoside Administering Feldene concomitantly with cardiac glycoside increases the risk of having cardiac failure and plasma glycoside levels.
Corticosteroids e.g., Prednisone Increases the risk of gastrointestinal ulceration or bleeding.
