Mefenamic Acid

Pain and inflammation affect millions worldwide, making pain management medications essential for daily life. Mefenamic tablets are commonly used to relieve various conditions, from menstrual pain to general body aches, making it a widely prescribed medicine in healthcare settings. Understanding mefenamic acid tablets helps patients use this medication safely and effectively. The following article explains everything about mefenamic acid tablets, including their proper usage, potential side effects, necessary precautions, and dosage guidelines. 

What is Mefenamic Acid?

Mefenamic acid belongs to the class of medications known as non-steroidal anti-inflammatory drugs (NSAIDs). This medication serves multiple therapeutic purposes through its ability to block specific substances in the body that cause pain, inflammation, and fever.

The medication demonstrates three primary properties that make it effective for various conditions:

• Anti-inflammatory effects to reduce swelling and inflammation
• Analgesic properties to relieve pain
• Antipyretic capabilities to reduce fever

The primary mefenamic tablet uses include:

• Treatment of mild to moderate pain conditions
• Management of menstrual pain and cramps
• Treatment of joint and dental pain

How to Use Mefenamic Acid Tablet

Proper administration of mefenamic acid pills ensures optimal therapeutic benefits while minimising potential side effects. 

The following are basic administration guidelines:

• Take the medicine with food or milk to prevent stomach upset
• Consume with 8-12 ounces of water
• Follow the prescribed dosing schedule strictly
• Start treatment at the first sign of pain or menstrual symptoms
• Never exceed the recommended duration of use
• For menstrual pain, patients should begin taking mefenamic acid at the onset of bleeding and pain. The treatment typically continues for 2-3 days during the menstrual cycle. When used for general pain management, the duration should not exceed 7 days unless specifically directed by a doctor.

  • Stomach bleeding or ulcers
  • Liver damage symptoms such as yellowing of skin or eyes
  • Kidney problems
  • Severe skin reactions, including Stevens-Johnson Syndrome

Precautions

Mefenamic acid requires careful consideration for specific groups of people. 

• Children: The medication is not recommended for individuals under 14 years of age. 
• Pregnancy and Lactation: Pregnant women, especially during the third trimester, should avoid using this medication as it may harm the developing baby. Breastfeeding mothers should also consult their doctor before taking mefenamic acid.
• Older Adults: Older adults are more prone to medication side effects, like stomach ulcers or intestinal bleeding.
• Medical Conditions: Individuals with certain medical conditions need additional monitoring when taking mefenamic acid. These include:
  • Heart disease or high blood pressure
  • History of stomach ulcers or bleeding
  • Kidney or liver disease
  • Asthma or breathing conditions
  • Fluid retention problems
  • Bleeding disorders
  • Dehydration
• Heart Surgery: Patients should not take mefenamic acid before or after heart bypass surgery. Those with a history of heart problems face an increased risk of cardiovascular events. 

How Mefenamic Tablet Works

The scientific mechanism behind mefenamic acid's effectiveness lies in its ability to inhibit prostaglandin synthesis. Prostaglandins play a crucial role in several disease processes, including inflammation, pain response, and fever. By stopping the body's production of prostaglandins through the inhibition of prostaglandin synthetase (cyclo-oxygenase), specifically COX-1 and COX-2, mefenamic acid effectively reduces these symptoms.

What makes mefenamic acid particularly unique among NSAIDs is its dual action mechanism. Not only does it prevent the formation of prostaglandins, but it also blocks their effects after they have been produced. This distinctive characteristic contributes to its effectiveness in managing various types of pain, particularly menstrual pain.

Can I Take Mefenamic with Other Medicines?

Medication interactions require careful consideration when taking mefenamic acid tablets. To ensure safe treatment, doctors need to know about all current medications, including prescription drugs, over-the-counter medicines, vitamins, and supplements.

Patients should inform their doctor if they are taking any of these crucial medications:

• Antacids containing magnesium hydroxide
• Antidepressants (SSRIs and SNRIs)
• Blood pressure medications (beta-blockers, ARBs, ACE inhibitors)
• Blood thinners such as warfarin
• Cancer treatments such as methotrexate and pemetrexed
• Diuretics (water pills)
• Heart medications like digoxin
• Immunosuppressants like cyclosporine
• Lithium for mental health conditions
• Other pain relievers, including NSAIDs and aspirin
• Serotonin-norepinephrine reuptake inhibitors (SNRIs)

Dosing Information

The correct dosage of mefenamic acid tablets varies based on the condition being treated and individual characteristics. 

Standard Adult Dosing:

• Initial Dose: 500 mg taken once
• Maintenance Dose: 250 mg every 6 hours as needed
• Maximum Duration for Pain: 7 days
• Maximum Duration for Menstrual Pain: 2-3 days

For optimal effectiveness, patients should begin treatment at the first sign of pain or menstrual symptoms. The medication demonstrates best results when taken with food or milk and adequate water (8-12 ounces).

Conclusion

Safety remains paramount when using mefenamic acid tablets, requiring regular communication with doctors and careful attention to potential mefenamic acid side effects or interactions. Patients must follow recommended dosing schedules, never exceed prescribed duration limits, and report any unusual symptoms promptly to their doctor. Medical supervision ensures safe and effective pain management while minimising potential risks associated with this medication.

2. Is mefenamic stronger than paracetamol?

Research indicates that mefenamic acid demonstrates better antipyretic activity than paracetamol. Studies show it provides more effective pain relief, particularly for conditions like menstrual pain and toothache. However, paracetamol remains the first choice for fever due to its established safety profile.

3. Does mefenamic acid make you sleepy?
