No and No. Buspirone is prescribed for anxiety. It takes at least 7-10 days of consistent dosing for effect -- can be longer in some. It is not habit forming. There are non-pharmaceutical ways to deal with anxiety also; consult with a therapist about this. Talk with your doctor about your concerns about medication. If it helps calm your anxiety & isn't addictive, it should help, not harm, your health.
No. No evidence that Buspirone ages anyone. Whether a medicine is indicated is a question to be discussed with your prescriber. All medications have risks, benefits and alternatives.
