Many people have suggested you talk to a doctor or pharmacist to answer your question directly. But I think you might be more curious about "why"? Why the anxiety now?
Problems with anxiety can have an environmental component as well as a result of heredity. Medications help with the symptoms in either case, but they will not resolve the issue long term.
In my experience (20+ years as a psychotherapist), you need to learn a new skill set - see a therapist, read some books about anxiety, and/or join a meditation/ mindfulness group in your community.
Take Good Care.
