Linezolid is an antibiotic that fights bacteria in your body. It is used to treat different types of infections.
Paroxetine (Paxil) is a medicine that can help treat depression and anxiety disorders. It belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs).
Linezolid treats pneumonia, skin infections, and infections caused by certain drug-resistant bacteria. It can treat pneumonia that you get in the hospital or in the community. It also treats complicated and uncomplicated skin infections, including diabetic foot infections. Linezolid can also treat infections caused by vancomycin-resistant Enterococcus faecium.
Paroxetine is used to treat several conditions in adults. These include major depressive disorder (MDD), obsessive compulsive disorder (OCD), panic disorder (PD), social anxiety disorder (SAD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). It helps to improve mood and reduce anxiety and panic feelings.
Linezolid works by stopping the growth of bacteria. It blocks bacteria from making proteins that they need to live and multiply. This helps your body fight off the infection.
Paroxetine works by increasing the amount of serotonin in your brain. Serotonin is a natural substance that helps regulate mood. By increasing serotonin levels, paroxetine can help improve symptoms of depression and anxiety.
