Nevertheless, awareness might help you be less anxious if you do experience any symptoms.

How to Manage Buspar Side Effects

Fortunately, there are a few tips you can use to manage the side effects of Buspar generic. 

Take at night: Some people may find that taking buspirone at bedtime on an empty stomach an hour before sleep can help manage daytime drowsiness. 

Stay hydrated: Consuming fluids regularly can help counteract dizziness or feelings of faintness that might be caused by dehydration. This can occur as a result of increased urination associated with taking Buspar generic. 

Practice self care: Self care acts — like doing yoga, meditating, eating healthy, doing deep breathing exercises, and working out — can be an excellent way to manage anxiety and reduce stress. If you’re experiencing side effects from Buspar generic, be kind to yourself and make sure you’re taking whatever steps you can to eliminate stress and anxiety from your days. 

Change your dose: If needed, you can talk with your prescribing doctor about changing doses, as a lower dosage might tend to have fewer adverse reactions. This way, you can adjust accordingly and still maintain efficacy without sacrificing too much in terms of unwanted symptoms. Just make sure to avoid a missed dose, as this can be dangerous for Buspar withdrawal if done frequently.

“Each anxiety medication lands on people differently. We need to be able to evaluate the pros and cons for us. But sometimes, a professional therapist can help us do that evaluation so we can put healthier lifestyle factors in place to manage the side effects. Deep breathing, grounding exercises, and mindfulness might aid in getting through heart attack-like or neurological symptoms. Reducing stress and increasing health can help us cope with cold symptoms.”
