Ketoprofen Suppositories by Pharmel Inc.

Common Name:


How does this medication work? What will it do for me?

Ketoprofen belongs to the group of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is used for the symptomatic treatment of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis.

Ketoprofen can also be used to treat pain associated with menstrual cramps and for the relief of pain after surgery (including dental surgery), pain after giving birth, and mild to moderate pain associated with sprains and strains. Ketoprofen relieves pain
and reduces swelling and inflammation by reducing a substance in the body that leads to inflammation and pain.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this
with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using 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 use this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

This medication is available as a 100 mg suppository.

How should I use this medication?

The recommended adult dose for rheumatoid arthritis and osteoarthritis is 150 mg to 200 mg daily. If given as a short-acting tablet, the dose should be divided into 3 or 4 equal doses throughout the day. Once the dose has been established,
some people can take their daily dose in 2 equal doses. If the maintenance dose is 200 mg, then the extended-release tablet may be taken once daily.

For treatment of menstrual cramps and mild-to-moderate pain, the recommended adult dose is 25 mg to 50 mg 3 or 4 times daily as needed.

The enteric-coated tablets or sustained-release tablets should be taken 1 or 2 hours before meals or at least 2 hours after meals. Ketoprofen short-acting capsules should be taken immediately after a meal or with food to reduce stomach upset.

You should not lie down for about 15 to 30 minutes after taking the medication. If stomach upset occurs and does not go away, contact your doctor. Ketoprofen tablets and capsules should always be swallowed whole.

Rectal suppositories provide an alternative form of the medication. One suppository can be used in the morning and evening (at bedtime) with appropriate use of ketoprofen tablets throughout the day as required. Ketoprofen suppositories should only be used rectally.

The total daily dose of ketoprofen should not exceed 200 mg (includes any combination of tablets and suppositories), except during severe flare-ups of rheumatic arthritis, when the dose may be increased to a maximum of 300 mg daily. In general, to reduce the risk of side effects, the lowest dose for the shortest period of time should be used.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way that you are using the medication without consulting your doctor.

It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not use a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
