Detailed Answer:
Hello thanks for choosing HCM for your health related queries
I can understand your concern. You have developed symptoms like shakiness of hands, anxiety and depression due to stress of clinical condition of your husband and have been advised to take Effexor.
Effexor is Venlafaxine and the drug is a good anti-depressant and anti-anxiety drug. If we go by pharmacology then the drug belongs to SNRI group of drugs. These drugs cause increased neurotransmission of SEROTONIN and NOREPINEPHRINE (both are neurotransmitters in brain, deficient in anxiety and depression) by causing change at receptors and molecular levels. This usually takes time of about 4 weeks. So in most of individuals when the drug is started they usually see increase in anxiety because of side effects of drug and then start showing improvement in about 4 weeks. You have been taking the drug since last one and half weeks only and no improvement in symptoms is seen, as per my opinion please wait for a couple of weeks and you will feel better and drug will start acting.
Thanks, Hope this helps you. Be assured you will feel better in some time. Please don't hesitate to ask again if you have more doubts.
Take care
