- BRAND NAME (Manufacturer)
-
- Ponstel (Parke-Davis)
-
- TYPE OF DRUG
-
- Nonsteroidal anti-inflammatory analgesic
-
- INGREDIENT
-
- mefenamic acid
-
- DOSAGE FORM
-
- Capsules (250 mg)
-
- STORAGE
-
- This medication should be stored in a tightly closed container at room
- temperature away from heat and direct sunlight.
-
- USES
-
- Mefenamic acid is used to treat painful menstruation. Mefenamic acid has
- been shown to block the production of certain body chemicals, called
- prostaglandins, that may trigger pain. However, it is not yet fully
- understood how it works.
-
- TREATMENT
-
- Mefenamic acid should be taken with food or antacids to lessen stomach
- irritation (unless your doctor recommends otherwise). Take this medication
- only as directed by your doctor. Do not take more of it or take it more
- often; and do not take it for longer than seven days at a time, unless your
- doctor tells you to do so. Taking too much of this medicine or using it for
- long periods of time may increase your chances of experiencing serious side
- effects.
- It is important to take mefenamic acid on schedule and not to miss any
- doses. If you do miss a dose, take it as soon as possible, unless it is
- almost time for your next dose. In that case, do not take the missed dose at
- all; just return to your regular dosing schedule. Do not double the next
- dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Bloating, constipation, diarrhea, difficulty in sleeping, dizziness,
- drowsiness, headache, heartburn, indigestion, light-headedness, loss of
- appetite, nausea, nervousness, soreness of the mouth, unusual sweating, or
- vomiting. As your body adjusts to the drug, these side effects should
- disappear.
- To relieve constipation, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads), exercise, and
- drink more water (unless your doctor directs you to do otherwise).
- If you become dizzy, sit or lie down for a while; get up slowly from a
- sitting or reclining position, and be careful on stairs. Avoid operating a
- car or potentially dangerous equipment.
-
- Major.
-
- If any side effects are persistent or particularly bothersome, you should
- report them to your doctor. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR
- about bloody or black, tarry stools; blurred vision; confusion; depression;
- difficult or painful urination; palpitations; a problem with hearing; ringing
- or buzzing in the ears; severe diarrhea; skin rash, hives, or itching; stomach
- pain; swelling of the feet; tightness in the chest, shortness of breath, or
- wheezing; unexplained sore throat and fever; unusual bleeding or bruising;
- unusual fatigue or weakness; unusual weight gain; or yellowing of the eyes or
- skin.
-
- INTERACTIONS
-
- Mefenamic acid interacts with several other medications:
- 1. Anticoagulants (blood thinners) such as warfarin can lead to an
- increase in bleeding complications if taken at the same time as mefenamic
- acid.
- 2. Concurrent use with aspirin, salicylates, or other anti-inflammatory
- medications can increase stomach irritation. Aspirin may also decrease the
- effectiveness of mefenamic acid.
- 3. Probenecid may increase blood levels of mefenamic acid, which may
- increase the risk of side effects.
- 4. The action of beta blockers may be decreased by this medication.
- 5. The drug can interact with diuretics (water pills).
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any listed above.
-
- WARNINGS
-
- * Tell your doctor if you have ever had unusual or allergic reactions to
- any medications, especially to mefenamic acid or to any of the other
- chemically related drugs (aspirin, other salicylates, diclofenac, diflunisal,
- fenoprofen, flurbiprofen, ibuprofen, meclofenamate, indomethacin, ketoprofen,
- naproxen, oxyphenbutazone, phenylbutazone, piroxicam, sulindac, or tolmetin).
- * Before taking mefenamic acid, it is important to tell your doctor if
- you now have or if you have ever had asthma, bleeding problems, colitis,
- stomach ulcers or other stomach problems, epilepsy, heart disease, high blood
- pressure, kidney disease, liver disease, mental illness, or Parkinson's
- disease.
- * If this drug makes you dizzy or drowsy, do not take part in any
- activity that requires alertness, such as driving a car or operating
- potentially dangerous machinery.
- * Because mefenamic acid can prolong your bleeding time, it is important
- to tell your doctor or dentist that you are taking this drug before having
- surgery or any other medical or dental treatment.
- * If you experience severe diarrhea while taking this medication, check
- with your doctor immediately. Do not take this medication again unless you
- first check with your doctor, because severe diarrhea can occur each time you
- take it.
- * Stomach problems are more likely to occur if you take aspirin regularly
- or drink alcohol while being treated with this medication. These should,
- therefore, be avoided (unless your doctor directs you to do otherwise).
- * If this drug is to be given to a child under 12 years of age, discuss
- the risks as well as the benefits with your doctor.
- * Be sure to tell your doctor if you are pregnant. This type of
- medication may cause unwanted effects on the heart or blood flow in the fetus.
- Also, studies in animals have shown that this type of medicine, if taken late
- in pregnancy, can increase the length of pregnancy, prolong labor, and cause
- other problems during delivery. Mefenamic acid has not been shown to cause
- birth defects in animals; however, studies in humans have not been conducted.
- Also, tell your doctor if you are breast-feeding. Small amounts of mefenamic
- acid pass into breast milk.
