Medicine for Anxiety
Types of Medicines Used for Anxiety
- SSRIs (Selective Serotonin Reuptake Inhibitors) Often the first choice for longer-term anxiety management. They work gradually to help balance mood-related chemicals in the brain.
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) Similar to SSRIs, these affect two brain chemicals and are used for ongoing anxiety management (PMC).
- Benzodiazepines Used for short-term, fast relief of intense anxiety symptoms. Because of dependence risk, they're generally recommended only for short periods.
- Buspirone A non-sedating option sometimes used for ongoing anxiety, with a lower risk of dependence compared to benzodiazepines.
- Beta-blockers Sometimes used to manage physical symptoms of anxiety, like a racing heart or trembling, particularly in specific situational anxiety.
- Tricyclic antidepressants An older class of medicines sometimes used for anxiety when other options haven't worked well, under close medical supervision.
How Do Medicines for Anxiety Work?
Medicines for anxiety work in different ways depending on their active ingredients. Some medicines, like SSRIs and SNRIs, work gradually over weeks by helping balance brain chemicals linked to mood and worry. Others, like benzodiazepines, act quickly by calming the nervous system for fast, short-term relief. That's why doctors often use a combination approach a fast-acting option for immediate relief and a longer-term medicine for ongoing management.
How to Choose the Right Medicine for Anxiety?
The right medicine depends on several personal factors, including:
- How severe your anxiety symptoms are
- How long you've been experiencing them
- Your age and general health
- Other conditions you may have, including depression
- Other medicines you're currently taking
- Your doctor's assessment and prescription
- Whether you also need help with sleep or physical symptoms
Dosage & How to Take Medicines for Anxiety
Dosage varies widely between different anxiety medicines, so there's no single dose that fits everyone. Always follow what your doctor has prescribed. General points to keep in mind:
- Take your medicine at the same time each day for consistency, especially with SSRIs/SNRIs
- Some medicines are best taken with food to reduce stomach upset
- If you miss a dose, don't double up check with your doctor or pharmacist on what to do
- Never stop anxiety medicines suddenly without medical advice, as some require gradual tapering to avoid withdrawal effects
- Give longer-term medicines time to work, and keep your doctor updated on how you're feeling
