Which medication is commonly prescribed for dysmenorrhea in a young girl?

1. Ibuprofen

2. Mefanamic acid

3. Naproxen

4. Acetaminophen

The correct answer is: Mefanamic acid

Mefenamic acid is commonly prescribed for dysmenorrhea, particularly in young females experiencing painful menstrual cramps. It belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs) and is specifically indicated for the relief of mild to moderate pain, including menstrual pain. Its effectiveness in reducing prostaglandin levels helps alleviate the uterine contractions that cause discomfort during menstruation. In clinical practice, mefenamic acid is favored for dysmenorrhea because it can provide significant pain relief while also addressing the underlying inflammatory processes contributing to menstrual cramps. Additionally, it is important to consider the patient's age, medical history, and possible side effects when prescribing. Other NSAIDs like ibuprofen and naproxen are also effective for managing dysmenorrhea, but mefenamic acid may be preferred in certain situations due to its specific formulation and dosing regimen. Acetaminophen, while helpful for pain relief, lacks the anti-inflammatory properties of other NSAIDs and may not be as effective for managing the specific symptoms of dysmenorrhea that involve inflammation and contraction of the uterus.
