Pregabalin

Pregabalin is an anticonvulsant that’s also prescribed for generalised anxiety disorder. It works by calming overactive signals in the brain, which can reduce symptoms of anxiety.

While effective for many, it can cause side effects like dizziness, sleepiness, or blurred vision. There’s also a risk of dependency if it’s misused or taken for long periods without review.

Buspirone

Buspirone is used for chronic anxiety. Unlike benzodiazepines, it’s less sedating and has a much lower risk of dependency.

Common side effects can include headaches, nausea, or dizziness, but it generally has fewer drowsy or “heavy” effects compared to benzodiazepines.

Other Medications That Might Help Anxiety

Sometimes, doctors might suggest other types of medication alongside or instead of pregabalin or buspirone:

• Antidepressants: Certain types, like SSRIs and SNRIs, are commonly used to treat anxiety disorders.
• Beta-blockers: Often used off-label for anxiety, especially for performance or situational anxiety. They block the effects of adrenaline, easing symptoms like shaking and a racing heart.
• Low-dose antipsychotics: Rarely, medicines like quetiapine may be prescribed in low doses for severe anxiety.
