Several effective options exist for anxiety, ranging from prescription medications to supplements and lifestyle changes. What works best depends on whether you’re dealing with occasional stress or a persistent anxiety disorder, and whether you want something that works immediately or builds relief over weeks.
Prescription Medications That Work Long-Term
The most commonly prescribed medications for generalized anxiety disorder are SSRIs and SNRIs. These work by preventing your brain from reabsorbing serotonin (and in the case of SNRIs, norepinephrine too), leaving more of these mood-regulating chemicals available in your brain. The result, over time, is a measurable reduction in anxiety levels.
Five medications are FDA-approved specifically for generalized anxiety disorder:
- Escitalopram (Lexapro), an SSRI
- Paroxetine (Paxil), an SSRI
- Venlafaxine XR (Effexor XR), an SNRI
- Duloxetine (Cymbalta), an SNRI
The critical thing to understand about these medications is that they don’t work right away. Most people need 4 to 6 weeks before feeling the full benefit, and it’s common for side effects like nausea or restlessness to show up before the anxiety relief does. That gap discourages a lot of people from sticking with treatment, but it’s a normal part of how these drugs work. Doctors typically start at a low dose and increase gradually.
Faster-Acting Prescription Options
Benzodiazepines like alprazolam (Xanax) and lorazepam (Ativan) reduce anxiety within 30 to 60 minutes, which makes them useful for acute panic or situational anxiety. They work by enhancing the effect of a calming brain chemical called GABA. The tradeoff is significant: benzodiazepines carry a real risk of physical dependence, and that risk climbs sharply with daily use beyond a few weeks. Most prescribers treat them as a short-term bridge while waiting for an SSRI or SNRI to take effect, not as a standalone long-term solution.
Hydroxyzine is another prescription option that works relatively quickly. It’s an antihistamine (related to Benadryl, but stronger) that also reduces anxiety without the dependence risk of benzodiazepines. Typical doses for anxiety range from 50 to 100 mg taken up to four times a day. The main downside is drowsiness, which can be significant.
Buspirone is a third prescription alternative that sits between these categories. It’s non-habit-forming and designed specifically for anxiety, but like SSRIs, it takes several weeks to reach its full effect. Clinical reviews show its overall effect size is modest, and it doesn’t appear to be more effective than SSRIs, SNRIs, or benzodiazepines. Still, some people respond well to it, particularly those who want to avoid both the dependence risk of benzodiazepines and the sexual side effects common with SSRIs.
Supplements With Clinical Evidence
If you’re looking for something you can buy without a prescription, a few supplements have enough research behind them to be worth considering, though none are as well-studied as prescription medications.
Ashwagandha is the most researched herbal option for anxiety right now. A joint taskforce from the World Federation of Societies of Biological Psychiatry and the Canadian Network for Mood and Anxiety Treatments has provisionally recommended 300 to 600 mg per day of ashwagandha root extract (standardized to 5% withanolides) for generalized anxiety. Clinical trials have found it significantly reduces stress and anxiety levels and lowers cortisol, your body’s primary stress hormone, compared to placebo. Benefits appear stronger at doses of 500 to 600 mg per day than at lower doses.
L-theanine, an amino acid found naturally in green tea, has shown anxiolytic effects at doses of 200 to 400 mg per day for up to 8 weeks. It works differently from most anxiety treatments. Rather than targeting serotonin or GABA directly, it promotes a calm, focused state without sedation. At those doses, the research suggests it’s both safe and effective for reducing stress in acute and chronic situations.
Magnesium is often marketed for relaxation and mood, though Mayo Clinic notes it hasn’t been proven in human studies to directly reduce anxiety. The biological rationale is real: magnesium is necessary for your body to produce serotonin, and it influences brain systems involved in mood regulation. If you’re deficient (and many adults are), correcting that deficiency could help. The recommended daily intake is 310 to 420 mg depending on your age and sex. Magnesium glycinate is the form most commonly suggested for mood support because it’s well-absorbed and less likely to cause digestive issues.
CBD: Still Mostly Unproven
CBD oil is widely marketed for anxiety, but the clinical evidence hasn’t caught up to the marketing. Trials are underway testing doses of 50 to 150 mg per day, but most completed studies are small, short-term, or focused on single-dose effects before a stressful event like public speaking. The quality and actual CBD content of consumer products also varies wildly, since the supplement industry isn’t tightly regulated. It’s not unreasonable to try CBD, but you should go in knowing that the evidence is preliminary and you may be paying a premium for an effect that could be partly placebo.
What Actually Helps Without Taking Anything
Exercise is one of the most consistently effective non-drug interventions for anxiety. Aerobic activity, even 20 to 30 minutes of brisk walking, triggers changes in brain chemistry that overlap with what medications do: increased serotonin, reduced cortisol, and release of endorphins. The effects are both immediate (a single session can lower anxiety for hours) and cumulative (regular exercise over weeks changes your baseline anxiety level).
Cognitive behavioral therapy, or CBT, is as effective as medication for many anxiety disorders and has longer-lasting effects after you stop. It works by helping you identify the thought patterns that fuel anxiety and replace them with more accurate ones. The practical skills you learn, like challenging catastrophic thinking or gradually facing situations you avoid, stay with you permanently. Many people get meaningful improvement within 8 to 12 sessions.
Breathing techniques that emphasize a slow exhale (longer out-breath than in-breath) directly activate your parasympathetic nervous system, the branch responsible for calming you down. This isn’t abstract wellness advice. Slow breathing measurably reduces heart rate and cortisol within minutes. It’s one of the few tools that works in the moment, during a panic attack or before a stressful event, with no side effects and no cost.
Choosing Based on Your Situation
If your anxiety is mild or situational (job interviews, flights, stressful periods at work), starting with L-theanine, exercise, and breathing techniques is reasonable. These carry no risks and can make a meaningful difference for everyday stress.
If anxiety is interfering with your daily life, relationships, or sleep on most days, that’s the territory where prescription medications and therapy have the strongest evidence. An SSRI or SNRI combined with CBT is the combination most supported by research for generalized anxiety disorder. The medication helps take the edge off while therapy builds the skills that keep anxiety manageable long-term.
If you need relief right now while waiting for a longer-term treatment to kick in, hydroxyzine or a short course of benzodiazepines can bridge that gap. Ashwagandha at 500 to 600 mg daily is a supplement-level option for the same purpose, with a milder effect but a favorable safety profile.
