After starting 50mg of pristiq (desvenlafaxine) i noticed my arms have become tired they hurt pretty much when i do anything and i wake every morning with nausea?

Pristiq (desvenlafaxine): Dear jaguar, Pristiq (desvenlafaxine) can cause nausea in up to 41% of people. Weakness/tiredness can also occur. Please let your prescribing physician know. Take care.

Likely due to the PR: Please see your prescribing physician to discuss. Options. Pritiq can cause nausea. It can also cause muscle aches, although less frequently. If a psychiatrist is not a member of your treatment team, now might be a good time to find one. Don't forget therapy, yoga, diet, exercise, relaxation therapy, spiritual counselin, meditation, and diet, exercise and acupuncture as other alternative options.
