Hi,
Both of these drugs belong to
SSRI (Selective serotonin reuptake inhibitor) drugs. Both are primarily used as anti-depressive drugs. The efficacy as well as side effects are also, almost same. However, some of the psychiatrists claim that
Paxil has more side effects than
Celexa. Hence, this may be the reason that your doctor might have thought to wean off you from Paxil and starting Celexa in its place.
In my opinion, as both belong to same group, therefore switching from Paxil to Celexa should not be a problem. It is all the more better that you are trying to wean off in a gradual tapering dose of Paxil. Still, it might have been a better choice, that dose of Celexa might also have been increased in a gradual increasing pattern like 10 mg of Celexa for 7-10 days & then increasing it to 20 mg of Celexa daily. However, this is just an opinion. The final choice of pattern of switching should be definitely under guidance of your psychiatrist.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Satnarain Bansal, General & Family Physician
