How long can I expect it to take my nre antidepressant Effexor (venlafaxine) to begin to work?

Two to Four Weeks: Most antidepressants, including Effexor (generic venlafaxine), begin working between two to four weeks. One must take into consideration the dose, the patient's age, and other medications being taken. My comments are quite general as each person's experience is unique. If you feel your medication is not working fast enough, share this with your doctor. ...Read more

Integrative approach: There are many pharmacological options for fibromyalgia but an integrative approach will be better long term. Integrative approach will address your lifestyle, nutrition, sleep and stressors of life. Incorporating an active lifestyle combined with healthy diet, mind and body therapy and lowest possible doses of medication is the way to go.

Do I take levothyroxine first thing am? How long do I need to wait to take Effexor (venlafaxine) XR (150mg) and clonazepam (.5mg) before I leave for work? Thx :)

Yes....: ...The levothyroxine (synthroid) is supposed to be taken on an empty stomach about 30 to 60 minutes before eating breakfast. Ideally you would take the Effexor (venlafaxine) xr with breakfast and the Clonazepam could be with breakfast as well if you take it on a regular basis. But if you are still feeling so tired, make sure you are getting your blood checked regularly, see your dr to discuss all factors. ...Read more

Can brain zaps (like the withdrawal from effexor) be from too little serotinin? No longer take it but still get them. Odd?

Ask Dr: Stopping an SSRI can be very challenging for some and it is very important to have close monitoring by a doctor of any symptoms that develop or stay. It needs to be done slowly and each person's characteristics can make a difference. It's worth doing but it must be done carefully. Don't try to handle it alone - you want the doctor to be responsible for these decisions. Glad you're better now! ...Read more

Can I wean off of Effexor (venlafaxine) XR 35mg, and take Zoloft 25mg at the same time, so there is no lapse in treatment? And how long until Zoloft starts working?

Yes, if doc agrees: Always discuss your plan of care with ur doc. It's most common 4 docs 2 recommend that patients reduce the dose of one med while they transition on to a new one, for the reason u mentioned -- no lapse. Docs call this a "cross taper". Unclear how long it will take for zoloft (sertraline) to work. Some pts feel btr in just a few days, while others may need up to 8 wks on the right dose. Ring ur doc to discuss :) ...Read more
