Mefenamic Acid: Quick Guide to Uses, Dosage & Safety

If you’ve been prescribed a pill called Mefenamic Acid, you probably want to know what it does and how to use it without hassles. In plain terms, it’s an NSAID – a non‑steroidal anti‑inflammatory drug – that helps lower pain and swelling. Think of it as a stronger cousin of ibuprofen, often used when regular painkillers aren’t enough.

How to Take Mefenamic Acid Correctly

Adults usually start with 500 mg taken three times a day, with food or a full glass of water to protect the stomach. Your doctor may adjust the dose, but the total shouldn’t exceed 1500 mg in 24 hours. If you miss a dose, take it as soon as you remember – unless it’s almost time for the next one, then just skip it. Never double‑up.

The medication works best when you keep a consistent schedule. Set an alarm or pair it with meals so you don’t forget. If you’re using it for menstrual cramps, many doctors suggest starting a day before pain begins and continuing for a few days, but always follow the exact plan your prescriber gave.

When to Call Your Doctor

Most people tolerate Mefenamic Acid well, but watch for red‑flag symptoms. Severe stomach pain, black stools, or vomiting blood mean you need medical help right away. Also, if you notice sudden swelling in the legs, shortness of breath, or a rash that spreads, call your doctor.

Common side effects include mild stomach upset, headache, or dizziness. These usually fade as your body gets used to the drug. If they linger or get worse, a quick chat with your pharmacist can help you decide whether to keep taking it.

Because Mefenamic Acid can affect blood clotting, avoid it if you have bleeding disorders or are taking blood thinners like warfarin. It can also raise blood pressure, so people with hypertension should monitor their numbers closely.

Pregnant or nursing mothers need extra caution. The drug is generally not recommended in the third trimester, as it may affect the baby’s heart. If you’re planning a pregnancy or are unsure, discuss alternatives with your healthcare provider.

Drug interactions are another piece of the puzzle. Tell your doctor about all meds you’re on – especially other NSAIDs, certain antidepressants, or lithium. Combining Mefenamic Acid with alcohol can increase stomach irritation, so it’s safest to limit drinks while you’re on the treatment.

To keep the stomach safe, consider taking a proton pump inhibitor or an antacid if your doctor suggests it. Staying hydrated and avoiding spicy or acidic foods can also reduce discomfort.

In summary, Mefenamic Acid is a useful tool for managing moderate to severe pain when other options fall short. Stick to the prescribed dose, watch for warning signs, and keep an open line with your doctor. With a little care, you can get the relief you need without unwanted surprises.
