Period pain (also known as menstrual cramps) is one of the most common concerns among women of reproductive age. It can feel like sharp spasms in the lower abdomen that usually extend to the back and thighs, and like a dull, throbbing pain. For some, discomfort is mild, but for most women, period pain can interfere with daily life, affecting productivity and overall quality of life. To combat period pain, there are so many period pain relief pills on the market; one such medicine is Ponstan 500 mg Tablets. This medicine helps to ease period pain and reduce heavy bleeding from periods, but doesn’t minimize the number of days your period lasts. It’s also known as mefenamic acid.
Normally, Mefenamic acid and Ponstan are the same medication; Ponstan is a brand name for the generic mefenamic acid. This medicine is a part of the drug class known as nonsteroidal anti-inflammatory drugs (NSAIDs) and is used to treat mild to moderate period pain. Ponstan is available by prescription from your healthcare provider. It is also available in a generic version, known as Generic Ponstan, through certified and licensed pharmacies. Generic Ponstan may provide effective relief from period pain at a more affordable, cost-effective price. In this blog, we will explore what Mefenamic Acid 500 mg is, how Ponstan 500 mg and Mefenamic Acid relieve menstrual pain, key warnings and precautions, possible side effects, usage instructions, and storage guidelines.

Mefenamic Acid 500 mg is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the action of an enzyme the body uses to make prostaglandins. These prostaglandins cause inflammation and stimulate pain; preventing their creation can result in reduced discomfort. It relieves pain associated with conditions such as menstrual cramps, muscle aches, headaches, joint pain, and dental pain. It also helps manage post-surgical pain, reduces fever, and alleviates inflammatory symptoms like redness and swelling. Additionally, it is effective in easing pain and discomfort from arthritis, muscular, and rheumatic conditions.
Ponstan 500 mg and Mefenamic Acid help relieve menstrual pain by performing the following functions.
Blocks Prostaglandins: It inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin production that leads to pain and inflammation in reproductive tissue.
Relaxes the Uterus: Lower prostaglandin levels mean fewer acute uterine contractions, which directly minimizes sharp cramping.
Reduces Heavy Flow: It also decreases heavy menstrual bleeding, which usually accompanies severe cramps.

Ponstan 500 mg tablet is a pain-relieving medicine used for conditions like headaches, fever, joint and muscle pain, post-operative pain, and menstrual cramps. It consists of mefenamic acid, an NSAID (non-steroidal anti-inflammatory drug) that helps minimize pain and inflammation by blocking certain chemical substances in the body.
Mefenamic Acid treats period pain by stopping your body from making prostaglandins. These natural chemicals make the muscles in your womb squeeze too hard, causing painful cramps. Lowering prostaglandin levels relaxes the womb and relieves pain.
The effect of Ponstan can be observed within 20-30 minutes of administration. The effect lasts for an average duration of 4-6 hours.
The common side effects of Ponstan include stomach upset, diarrhea, vomiting or light-headedness, and constipation. Most serious side effects may include black stools, severe allergic reaction, or vomit that appears to be coffee grounds, bruising or bleeding more easily than usual, swollen ankles, bleeding from the back passage, or a stiff neck.
Patients with a known allergy should not use mefenamic acid or any other components present in the formulation. Those who have allergies from asthma or urticaria should not take mefenamic acid since it may worsen their condition. Patients with severe liver or kidney disease, or those who have a history of gastrointestinal bleeding, should not use mefenamic acid tablets. If you are 65 years of age or older, or if you smoke, do not take this medicine.
