How does this medication work? What will it do for me?
Tenoxicam belongs to the class of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is used to relieve the inflammation, swelling, stiffness, and pain associated with rheumatoid arthritis, osteoarthritis, ankylosing spondylitis (a type of arthritis involving the spine), tendonitis (inflammation of a tendon), bursitis (inflammation of a bursa, a fluid-filled sac located around joints and near the bones), and periarthritis of the shoulders or hips (inflammation of tissues surrounding these joints).
Tenoxicam works by interfering with the production of compounds in the body that cause pain and inflammation. Tenoxicam may begin to work early in the treatment but for certain types of arthritis up to 2 weeks may pass before you notice the full benefits of this medication.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each yellow, oval, biconvex, film-coated tablet, engraved "20" and partially bisected on one side, contains 20 mg of tenoxicam. Nonmedicinal ingredients: colloidal silicon dioxide, croscarmellose sodium, hydroxypropyl methylcellulose, lactose hydrous, magnesium stearate, microcrystalline cellulose, polydextrose, polyethylene glycol, titanium dioxide, yellow ferric oxide, and carnauba wax.
How should I use this medication?
The recommended adult dose of tenoxicam is 20 mg taken once daily. Some people may require lower doses to control pain and inflammation. Higher doses are not recommended as they do not provide any additional benefit.
This medication should be taken at the same time each day and immediately after a meal or after food to avoid stomach upset.

HEALTH CANADA ADVISORY
June 8, 2021
Health Canada has issued new information concerning the use of non-steroidal anti-inflammatory drugs (NSAIDs). To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
A previous advisory on non-steroidal anti-inflammatory drugs (NSAIDs) was issued on October 30, 2020.
Heart disease: Like other NSAID medications, tenoxicam may cause fluid retention and swelling. This increases the amount of work your heart must do, causing increased blood pressure and heart failure. People with a history of heart conditions should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
History of stomach ulcer or stomach bleeding: Tenoxicam may cause stomach problems. If you notice signs of bleeding from the stomach, such as bloody or black tarry stools or vomiting a coffee-ground like substance, stop taking this medication and get medical attention right away.
People with a history of stomach ulcers or stomach bleed should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Like other NSAID medications, tenoxicam increases the risk of decreased kidney function. People with reduced kidney function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: People with reduced liver function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Potassium levels: There is a risk of high blood potassium levels with NSAID treatment. People most at risk include seniors; those having conditions such as diabetes or kidney failure; and those taking beta-adrenergic blockers, angiotensin converting enzyme (ACE) inhibitors, or some diuretics (water pills). While on tenoxicam, your doctor will periodically monitor your blood potassium levels.
Vision: Blurred or decreased vision have been reported by some people taking tenoxicam. If you experience any changes in vision, speak to your doctor immediately. If you are receiving tenoxicam for an extended period, your doctor may periodically request that ophthalmic exams be done.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking tenoxicam, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children and adolescents: The safety and effectiveness of using this medication have not been established for children and adolescents less than 16 years of age.
Seniors: Seniors are more likely to experience the harmful effects of this medication. Lower doses may be required.
