<p>Feeling anxious? Check your medicine cabinet.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>There are millions of reasons why you might be feeling more anxious than usual, from big life changes to small triggers, dehydration to medical conditions — not to mention COVID-19 and the current political upheaval. If you’ve recently started experiencing anxiety that’s disrupting your life, it could also be a side effect of a medicine you take. Many drugs — even those that seemingly have nothing to do with the brain — list anxiety as a possible side effect.</p>

<p>Each drug affects every person differently and can interact with other drugs, supplements, conditions or even food to produce side effects, including <a href="https://medshadow.org/anti-anxiety-meds-options-side-effects-alternatives/" target="_blank" rel="noreferrer noopener">symptoms of </a><a href="https://medshadow.org/anti-anxiety-meds-options-side-effects-alternatives/" target="_blank" rel="noreferrer noopener">anxiety</a>. If you think drugs may be causing your anxiety, be sure to talk to your healthcare provider about how to manage it or whether it’s time to taper off, switch or stop the medication. Nearly every medicine has an alternative drug that might affect you less. Even better, <a href="https://medshadow.org/therapy-meditation-sleep-and-exercise-can-help-lessen-anxiety/" target="_blank" rel="noreferrer noopener">incorporate frequent </a><a href="https://medshadow.org/therapy-meditation-sleep-and-exercise-can-help-lessen-anxiety/" target="_blank" rel="noreferrer noopener">exercise</a> and <a href="https://medshadow.org/the-link-between-gut-health-anxiety-and-depression/" target="_blank" rel="noreferrer noopener">healthy, whole-food eating habits</a> and you may be able to use fewer drugs.</p>
