Another commonly used anti-anxiety medication is SSRIs (selective serotonin reuptake inhibitors). Some examples of these are Paroxetine and Sertraline These work by increasing serotonin, which is a chemical messenger, or neurotransmitter in the brain. Serotonin is associated with mood and anxiety regulation thus a higher level of serotonin may help a person struggling with anxiety. This treatment is often, as with other anxiety medications, used to treat depression. One big difference between SSRIs and Benzodiazepines is that unlike Benzodiazepines SSRIs do not work immediately. They take 4 to 6 weeks to begin seeing results. While they are mostly safe there are some side effects with the most serious being suicide. The risk of potential suicide in people on SSRIs doubles compared to someone who is not taking it. Similar to SSRIs are Tricyclics such as clomipramine and imipramine. They work by allowing serotonin and norepinephrine (another neurotransmitter, and stress hormone) to be available to your brain. 

The last main group of anxiety medication this article will discuss is beta blockers, more commonly used for treating heart conditions. They reduce blood pressure by blocking the hormone epinephrine. A commonly used beta blocker is propanol. They are often used for short-term episodes such as before someone enters a stressful situation. They can help with a fast heart rate, a shaky voice, dizziness, etc., before a big event. In short, they decrease your body's reaction to stress, which might allow you to feel less stressed.
