Which medication classes are NOT used to treat premenstrual syndrome?

In the context of treating premenstrual syndrome (PMS), certain medication classes are recognized for their effectiveness, while others are not typically utilized for this purpose. An understanding of the roles of these medications helps clarify why the selected answer is appropriate.

Analgesics and calcium supplements, while beneficial for managing specific symptoms associated with PMS (such as menstrual cramps and mood swings), are not considered primary treatments for the syndrome itself. Analgesics, such as NSAIDs, may alleviate pain but do not address the underlying hormonal imbalances or psychological symptoms of PMS. Calcium supplementation has been researched primarily for its effects on mood and PMS symptom severity, but it is not a frontline treatment; instead, it may serve as an adjunctive measure.

In contrast, other options such as SSRIs (selective serotonin reuptake inhibitors) and diuretics are well-established in the management of PMS symptoms, particularly for mood-related issues and fluid retention, respectively. Similarly, benzodiazepines and progestins may be indicated in certain cases, such as for anxiety management or hormonal therapy.

Understanding the therapeutic categories and their application in clinical settings helps highlight the roles of various medications in treating PMS, showcasing why analgesics and calcium are less central in this context.
