Buspirone: The 'U 247' Anxiety Medication
The white rectangular pill imprinted with 'U 247' is Buspirone Hydrochloride, a non-addictive antianxiety medication prescribed for managing anxiety disorders. It is not related to sedative/hypnotic drugs like benzodiazepines, meaning it does not cause the same level of sedation or carry the same risk of dependence. The tablets are manufactured by Unichem Pharmaceuticals (USA), Inc., and the imprint 'U' helps to distinguish it from other pills.
How Buspirone works
Buspirone's mechanism of action is distinct from other anxiety medications. It is believed to work by affecting levels of serotonin and dopamine in the brain. Specifically, it acts as a partial agonist at serotonin 5-HT1A receptors and has a moderate affinity for brain D2-dopamine receptors, helping to regulate mood and anxiety. This interaction with neurotransmitters results in a gradual, rather than immediate, calming effect. Patients should note that it may take several weeks of consistent use to experience the full therapeutic benefits.
Therapeutic uses of Buspirone
Buspirone is primarily prescribed for the management of generalized anxiety disorder (GAD). It helps to relieve a range of anxiety symptoms, including fear, tension, irritability, and restlessness. Its non-sedating nature makes it a suitable option for long-term treatment, unlike benzodiazepines, which are often reserved for short-term use due to their potential for dependence.
Dosage and administration
For the U 247 tablet, which is 30 mg, the standard dosage is determined by a healthcare provider. The rectangular tablet is scored and can be broken into two or three smaller segments to allow for flexible dosing (30 mg, 20 mg, 15 mg, or 10 mg). Doses should be taken consistently with or without food to ensure proper absorption. A typical starting dose is 15 mg daily, divided into two doses (7.5 mg twice a day), which may be adjusted by a doctor.
Potential side effects
As with all medications, buspirone can cause side effects. It's important to be aware of the most common ones, as well as those that are less frequent or more serious.
Common Side Effects:
- Central Nervous System (CNS) effects: Dizziness, drowsiness, headaches, and nervousness are frequently reported.
- Gastrointestinal effects: Nausea and upset stomach are possible side effects.
- Sleep disturbances: Insomnia or sleep problems can occur, though drowsiness is also a possibility.
- Fatigue: Some individuals may experience unusual tiredness or weakness.
Serious Side Effects:
Serious side effects are rare but require immediate medical attention. These include:
- Chest pain
- Shortness of breath
- A light-headed feeling, as if you might pass out
- Development of serotonin syndrome (especially when combined with other serotonergic drugs)
Contraindications and interactions
Buspirone should not be used in combination with Monoamine Oxidase Inhibitors (MAOIs), as this can lead to a dangerous interaction causing high blood pressure or serotonin syndrome. Other important drug interactions exist, and patients should always inform their doctor of all medications, supplements, and herbal products they are taking. For instance, certain substances that inhibit the enzyme CYP3A4, such as grapefruit juice and specific antibiotics, can increase buspirone levels and lead to adverse effects.

Conclusion
Recognizing a pill by its imprint is a crucial step in understanding the medication, but it should never replace professional medical advice. The white rectangular tablet with the imprint U 247 is Buspirone Hydrochloride 30 mg, an effective anti-anxiety agent, but it must be used as prescribed. If you have found this or any other medication and are unsure of its purpose, always consult a qualified healthcare professional. Never self-medicate or share prescription medications. This ensures proper treatment and avoids potentially serious health risks associated with improper drug use.
