I've taken 20mg of celexa, now paxil (paroxetine). they don't do anything. does that mean i'm resistant, need higher dosages, different ads?

Possible..: You did not say what you are taking the Celexa and Paxil (paroxetine) for. If it is for depression and or anxiety, talk to your prescribing md to see if a different class of medication, a higher dose or addition of another medication or psychotherapy will be good for you.

What are they treating: I can't from your question exactly what you are being treated for. I am going to make an assumption that you are being treated for depression in the answer to this question. You need to give Paxil at least eight weeks to see whether it's going to help. If you don't feel any improvement within six weeks however, most doctors would change to a drug from another class or add in low-dose abilify (aripiprazole). You should also make use of psychotherapy and other modalities of treatment that a therapist can discuss with you. As far as the medication goes however, there is a broad variety of antidepressants available and if you will just hang in there, that you will eventually find a response. It could even take more than one antidepressant at a time. Other medications that are periodically added on to an antidepressant are lithium if you're on a try cyclic antidepressant, thyroid hormone, and seroquel. There are various types of psychotherapy as well with the best outcomes seen with cognitive behavioral therapy.

Some questions ...: Has bipolar been ruled out? Did you take the Celexa (citalopram) for at least one month? It is preferable to increase the dose before switching (20 mg is a starting dose). Were you taking other meds at the same time? Some meds can interfere with ssri's. Have you tried counseling? Are you making positive changes to your lifestyle? Getting exercise? Watching your diet? Getting good quality sleep?

If could mean all of: These things. You might not be on an adequate dose. You may not have been on it long enough. It may not be the most effective med for you. See that you suffer from anxiety. Don't give up on the meds yet. In the meantime make other lifestyle changes that will help your anxiety.Talk about feelings ; address problems. Don't avoid them. Aim for 7.5 - 8 hours of sleep/ night. Daily physical activity.
