Ponstel

Ponstel (mefenamic acid) is a prescription nonsteroidal anti-inflammatory drug (NSAID) specifically indicated for the relief of moderate pain and the treatment of primary dysmenorrhea. It belongs to the fenamate class of NSAIDs and works by inhibiting the body’s production of prostaglandins, hormone-like substances that cause inflammation, pain, and fever. By targeting the root cause of menstrual cramping and other inflammatory pain, Ponstel provides a mechanism-focused approach to symptom management, offering patients a specialized option when other analgesics may be insufficient. Its use is directed by healthcare professionals who determine its appropriateness based on an individual’s medical history and presentation.

Features

• Active Ingredient: Mefenamic acid (500 mg per capsule in initial dose form)
• Drug Class: Nonsteroidal anti-inflammatory drug (NSAID), fenamate derivative
• Mechanism of Action: Cyclooxygenase (COX) enzyme inhibitor, reducing prostaglandin synthesis
• Administration: Oral capsule
• Prescription Status: Rx-only medication
• Manufacturer Variations: Available as a branded and generic product from multiple pharmaceutical companies

Benefits

• Provides targeted relief from moderate pain, specifically associated with menstrual cramps (dysmenorrhea)
• Reduces inflammation at the source by inhibiting prostaglandin production, rather than merely masking pain signals
• Offers a short-term treatment option with a defined dosing schedule, minimizing long-term systemic exposure
• Can decrease the need for additional analgesic medications when used as directed under medical supervision
• Helps improve quality of life during menstrual cycles by alleviating debilitating cramping and associated symptoms
• Possesses both analgesic and anti-inflammatory properties, addressing multiple components of pain

Common use

Ponstel is primarily prescribed for the short-term relief of moderate pain in patients 14 years of age and older. Its most common and well-established use is for the treatment of primary dysmenorrhea, helping to manage the severe uterine cramping, lower back pain, and associated symptoms that occur with menstruation. It may also be used off-label for other types of acute, inflammatory pain as determined by a healthcare provider, but it is not typically indicated for chronic pain conditions due to its potential side effect profile with prolonged use. Treatment is generally limited to a few days during the menstrual period rather than continuous administration.

Dosage and direction

For acute pain and dysmenorrhea in adults and adolescents over 14 years: The recommended initial dose is 500 mg (one capsule), followed by 250 mg every 6 hours as needed for pain relief. Treatment should not exceed one week. Ponstel should be taken with food or milk to minimize gastrointestinal upset. The capsules must be swallowed whole with a full glass of water; they should not be crushed, chewed, or broken. Patients should use the lowest effective dose for the shortest duration possible to achieve treatment goals while minimizing risks. Dosage adjustments are necessary for elderly patients or those with renal impairment, under strict medical guidance.

Precautions

Patients should inform their healthcare provider of any history of cardiovascular disease, hypertension, gastrointestinal disorders (especially ulcers or bleeding), renal or hepatic impairment, asthma, or bleeding disorders before starting Ponstel. Use with caution in patients over 65 years, as they may be more susceptible to NSAID-related adverse effects. Avoid alcohol consumption during treatment, as it may increase the risk of gastrointestinal bleeding. Ponstel may cause dizziness or drowsiness; patients should avoid driving or operating machinery until they know how the medication affects them. Regular monitoring of renal function, blood pressure, and complete blood count may be recommended during treatment.

Contraindications

Ponstel is contraindicated in patients with known hypersensitivity to mefenamic acid, aspirin, or other NSAIDs, manifested by asthma, rhinitis, urinalgia, or anaphylactoid reactions. It should not be used in patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Contraindications include peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery. Use is prohibited in patients with a history of gastrointestinal bleeding or perforation related to previous NSAID therapy. It is contraindicated in patients with severe renal impairment or active peptic ulcer disease. Should not be used in the third trimester of pregnancy.

Possible side effect

Common side effects may include gastrointestinal symptoms such as dyspepsia, nausea, vomiting, diarrhea, constipation, and abdominal pain. Central nervous system effects like dizziness, headache, nervousness, and drowsiness may occur. Dermatological reactions including rash and pruritus have been reported. Serious but less common side effects require immediate medical attention: signs of gastrointestinal bleeding (black/tarry stools, vomiting blood), symptoms of heart problems (chest pain, shortness of breath, weakness), signs of liver problems (nausea, fatigue, jaundice), allergic reactions (hives, facial swelling, difficulty breathing), and signs of kidney problems (changes in urination, swelling).

Drug interaction

Ponstel may interact with anticoagulants (warfarin) increasing bleeding risk. Concurrent use with other NSAIDs or aspirin may increase gastrointestinal toxicity. ACE inhibitors, angiotensin receptor blockers, and diuretics may have reduced effectiveness when taken with Ponstel. It may increase lithium levels and methotrexate toxicity. Concomitant use with corticosteroids increases the risk of GI ulceration. Cyclosporine and Ponstel may increase nephrotoxicity risk. Ponstel may reduce the antihypertensive effect of beta-blockers. It may increase the risk of bleeding with antiplatelet agents and SSRIs. Monitoring is required when used with drugs that are highly protein-bound.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one. Given that Ponstel is typically used on an as-needed basis for pain relief rather than on a strict schedule, the concept of “missed dose” applies primarily to the maintenance dosing after the initial dose when used for multi-day treatment. Patients should maintain at least 6 hours between doses to avoid exceeding recommended dosing intervals.

Overdose

Symptoms of overdose may include drowsiness, nausea, vomiting, epigastric pain, gastrointestinal bleeding, coma, or renal failure. In severe cases, respiratory depression and metabolic acidosis may occur. Management is supportive and symptomatic with gastric lavage or activated charcoal if presentation is early. Hemodialysis is not effective due to high protein binding. Forced diuresis, alkalinization of urine, or hemoperfusion may not be useful. Specific attention should be paid to electrolyte balance, renal function, and respiratory status. Patients experiencing suspected overdose should seek immediate medical attention or contact a poison control center.

Storage

Store at room temperature between 20°C to 25°C (68°F to 77°F), with excursions permitted between 15°C to 30°C (59°F to 86°F). Keep in the original container, tightly closed, and protect from light and moisture. Do not store in bathroom areas where humidity levels fluctuate. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused medication after the treatment course is completed, preferably through a drug take-back program or according to FDA-recommended disposal methods if no take-back program is available.

The complete prescribing information should be consulted before initiating treatment. Never adjust dosage or discontinue medication without consulting your healthcare provider. Report any adverse effects to your physician promptly.

Reviews

Clinical studies have demonstrated Ponstel’s efficacy in managing dysmenorrhea, with many patients reporting significant reduction in pain scores compared to placebo. Patients often describe effective relief from menstrual cramps within hours of the initial dose. Some users report gastrointestinal side effects as a limitation, particularly when taken without food. Healthcare providers note its specific utility for menstrual pain but emphasize the importance of short-term use and appropriate patient selection. The medication receives mixed but generally positive assessments from both patients and clinicians when used for its indicated purpose under proper medical supervision.
