Yes, Paxil (paroxetine) is known to commonly cause a loss of appetite as a side effect. This is because Paxil affects the levels of certain neurotransmitters in the brain that regulate appetite and satiety.
In addition to loss of appetite, other common side effects of Paxil include nausea, vomiting, diarrhea, headache, dizziness, and difficulty sleeping. These side effects are generally temporary and may go away after a few weeks of treatment.
If you are experiencing loss of appetite or other side effects while taking Paxil, it is important to talk to your healthcare provider. They may be able to adjust your dosage or recommend other treatment options that can help manage your symptoms. It is important not to stop taking Paxil or change your dosage without first consulting with a healthcare professional, as sudden changes in dosage can lead to withdrawal symptoms or other complications.
