AnxietyAnxiety is a feeling of apprehension and fear characterized by symptoms such as trouble concentrating, headaches, sleep problems, and irritability. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults. Treatment for anxiety may incorporate medications and psychotherapy.
Buspar vs. Zoloft (Differences between Side Effects and Uses)
Buspar (generic name buspirone) and Zoloft (generic name setraline) are medications used for the treatment of anxiety. Researchers do not know how Buspar works in treating anxiety, but, research suggests that it involves the chemicals that the nerves use to communicate with each other (neurotransmitters). Zoloft is an antidepressant that belongs to the drug class selective serotonin reuptake inhibitors (SSRIs). SSRIs change the levels of serotonin in the brain, which may restore the chemical balance among neurotransmitters.
Zoloft also is used to treat:
- Post-traumatic stress disorder (PTSD)
- Premenstrual dysphoric disorder (PMDD)
- Social anxiety disorder
- Obsessive compulsive disorder (OCD)
- Panic disorder
Buspar and Zoloft have common side effects that are similar, for example:
- Erectile dysfunction
- Decreased interest in sex
- Problems having an orgasm
- Feeling tired
- Dry mouth
Other side effects of Buspar include:
- Skin rash
- Unsteady gait
Zoloft has a Black Box Warning because antidepressants increase the risk of suicidal thoughts and behavior in pediatric patients and young adult patients in short-term studies. Patients meeting this criteria should be closely monitored for worsening depression and suicidal thoughts and behaviors.
Both Buspar and Zoloft have different, but important drug interactions. Neither drug is recommended to use if you are pregnant or breastfeeding.
