Taken 375mg of Effexor (venlafaxine) for 2+ yrs. Lost 33 lbs. Can weight loss effect the drug or does it make 0 diff. In effectiveness? Want to lower my mg if so

Talk to your doctor : Your are on a hefty dose of Effexor (venlafaxine). Talk with your doctor before making any changes. I have seen some patients lose weight on their medicine. If you and your doctor determine that this is the maintenance dose required to manage your symptoms, then don't change. If your weight loss continues and poses a health risk, then you may need a dose adjustment or med change. Best wishes! ...Read more

How unsafe is it to mix Effexor (venlafaxine) with recreational drugs?

How unsafe is it to mix Effexor (venlafaxine) with recreational drugs?

Yes: The scariest possibility is that the propensity of Effexor (venlafaxine) to elevate blood pressure without the presence of recreational drugs would be potentiated in the presence of any substance with a capacity for elevating blood pressure to the point of producing a catastrophic event such as a cerebrovascular hemorrhage. Also there is serotonin syndrome and hyponatremia in addition to severe behavior change. ...Read more

Feeling tired: Feeling tired after taking the effexor may or may not resolve. Somnolence occurs with lexapro 10% or more. Somnolence can occur with effexor up to 20%. See: https://www.drugs.com/sfx/lexapro-side-effects.html. And see: https://www.drugs.com/sfx/effexor-side-effects.html. My patients on lexapro usually have little in the way of side effects.

Talk to your doctor : This is a good combination of medication. These meds are usually well-tolerated. Talk to your doctor about the risks, benefits and side effects of your treatment. If needed, your doctor can order tests to monitor your liver. We look for a yellow coloration to the white part of the eye or yellowing of the skin (jaundice) which suggests liver injury or disease. Talk to your doctor. Best wishes! ...Read more

I got prescribed the drug effexor (venlafaxine)....Prob not spelling it right....Anti depressent drug....Heard a lot of bad stuff aobut it im afraid to take it?

Effexor (venlafaxine): I agree with dr pappas. Please remember few go out of their way to tell others or post on the internet the expected "run-of-the-mill" affect of a medication. Rather, you are likely to hear or read the most positive or negative experiences. Your doctor evidently has confidence the medication is correct for you. Speak to your doctor about your concerns and clarify what your expectations should be. ...Read more

Been off Effexor (venlafaxine) for a week....Feeling nauseated and a little dizzy i came on a one-day trip with my husband and left medicine at home. One day trip turned into a week without meds.

Been off Effexor (venlafaxine) for a week....Feeling nauseated and a little dizzy i came on a one-day trip with my husband and left medicine at home.  One day trip turned into a week without meds.

Effexor (venlafaxine) : Effexor (venlafaxine) is a serotonin—norepinephrine reuptake inhibitor medication. If you abruptly stop taking it you can develop a discontinuation syndrome. Some of the symptoms of a discontinuation syndrome with Effexor can include feeling restless, irritability, aggression and depressed mood. Some of the GI effects can include nausea and abdominal bloating. Dizziness, brain zaps (electrical sensation), feeling tired and the sense that things are spinning (vertigo) can occur. You could develop bizarre dreams, see things that aren’t there or hear things when there isn’t really noise. Because of it’s short half life there is a high risk of withdrawal symptoms with effexor, which can sometimes occur with as little as one missed dose. I recommend that if you ever forget your medications while on vacation, that you call the doctor who prescribed them. Ask the doctor to phone in a temporary prescription to a pharmacy that is close to where you are staying. Make sure you supply the name and phone number of the pharmacy. Please call your doctor to advise him or her of your situation. ...Read more

No EnergyWt.Loss Dx: Low energy (asthenia) is a side effect found in greater than 10% of people taking venlafaxine. Weight loss occurs in 1-6% of people taking this medication. So it is possible that the drug is causative. However, an 80 lb weight loss and no energy is significant enough to warrant a doctor to look for other medical concerns that could be causing these sympotms. ...Read more

Taking Effexor (venlafaxine) XR cause me to test positive on a drug test? I have been on Effexor (venlafaxine) XR for 3 years.

No: Drug tests are usually looking for specific drugs of abuse. They don't check for any and all drugs you are taking. The only way Effexor (venlafaxine) will show up is if they specifically look for effexor, (venlafaxine) and there is no good reason for them to do that. ...Read more

Is there another drug that I can be switched to from Effexor (venlafaxine) XR without going through withdrawal that I have read about on line. ?

Is there another drug that I can be switched to from Effexor (venlafaxine) XR without going through withdrawal that I have read about on line. ?

Yes.: Switching from effexor (venlafaxine) to another antidepressant is generally accomplished by doing a "cross taper" - starting the new med at a low dose and decreasing the effexor (venlafaxine) a bit with a gradual decline in the effexor (venlafaxine) and increase in the new med. This generally avoids any of the withdrawal effects. P.S. not all patients have withdrawal effects from antidepressants. ...Read more

I am under a doctor's care and currently weaning off of 15 years of using Effexor (venlafaxine) 150 mg daily. Why is it such an ordeal with this drug?  Horrible .

Yes.: Getting off antidepressant is not a pleasant experience and may take a lot longer than you think. The secret is to gradually wean by small increments and if symptoms occur, go back to the last dose that you felt good at then wait a few days and decrease by12.5 mg at a time for a week then decrease again in a week . Increase your exercise level and continue following your doctor's advise. ...Read more

I switched from 200mg of Zoloft a day to 75mg of Effexor (venlafaxine) a day. I feel funny. Is it the change in medicine that's causing it? Dizzy and funny feeling

Yes: This change in meds could be producing the "funny feeling" you describe. Both meds act on similar and different neurotransmitter systems (serotonin and norepinephrine). It may be been an easier transition to taper a little more slowly with Zoloft (Sertraline) and add Effexor (venlafaxine) at a lower dose (37.5mg) to adjust. ...Read more
