There is no single over-the-counter medication that cures short-term memory loss. Memory issues can stem from various underlying causes, including vitamin deficiencies (like B12), thyroid imbalances, high stress, poor sleep, or early cognitive decline. Before starting any medication, it is crucial to consult a doctor. They can perform blood tests and cognitive evaluations to determine the exact cause. Depending on the diagnosis, treatment may involve lifestyle adjustments, managing underlying health conditions, or specific prescription medications. Please avoid self-medicating and schedule an appointment with your healthcare provider for a proper medical evaluation.
