603543 tn?1255294450 Good Afternoon, It is worth noting that Wyeth Pharmaceuticals currently has a patent for Effexor XR. While there is a generic extended release version of venlafaxine available, it is not exactly the same as the brand name (Because of the patent). The headaches you are experiencing may be caused by some of the inert ingredients in the generic brand. Knowing this, I would take the samples back to your Dr. and continue using the brand name since you already know it works for you.
Avatar n tn You also need to check if Generic Effexor XR is avalible in your area of the world. I heard that the patent was up and this means that it should be avalible in a generic formula that is the same as Effexor XR. If not then you doctor should have no problem writing you a script for the name brand Effexor XR. Just call him and say "hello doc, thatks for the generic Venlafaxine, but I prefer name brand Effexor XR." He should have no problem with this at all.
Avatar n tn Ahh Pristiq, The new SSNRI. Actualy just a slight tweek on Effexor XR. Interesting fact about Pristiq..... Wyeth's newest Antidepressant medication Pristiq, is actually kind of a sister drug of Effexor XR. In fact in terms of the active ingrediants molecular structure they are about 98% the same. You know why the Drug Company Wyeth would produce a drug so much like Effexor XR?
Avatar f tn Hey Kelly, nice to see you, though the reason su_cks! I've not heard of anyone or remember lol seeing it mentioned here, so i did a quick search and drugs .com states...... "In a trial testing the use of memantine (the active ingredient contained in Namenda XR) in MS patients with cognitive impairment, nine out of nineteen patients reported a worsening of their neurologic symptoms that deteriorated their quality of life.
1796524 tn?1315586487 Watch out for "CR", "XR" and "SR" versions of meds. As far as I know, only Wellbutrin "CR" and Effexor "XR" are superior than the originals. I was taking 6mg's of Klonopin/day for many years before swiching to Xanax, also 6mg's/day. I suffer severe anxiety, and although the K-pins were O.K., they took too long to work and didn't stop panic attacks.
20003388 tn?1515166040 I'm just curious if anyone has been on Namenda and could tell me how long the initial brain fog lasted for you? I just started Namenda yesterday, 5 mg a day for 1 week then 10 mg a day in divided doses. I have memory issues and severe cognitive impairment. I was put on Namenda by a neurologist after a thorough examination. I expect the brain fog from starting Namenda up but am just trying to get a time frame for when I could expect the initial brain fog to wear off. Thanks everyone.
Avatar f tn I tried Pristiq in an attempt to help with menopausal symptoms. I was (and am) on Effexor XR, and Pristiq is almost identical to Effexor XR. I think the only difference is in their molecules. I didn't find Pristiq any better (for me) than Effexor XR, so I went back to Effexor XR. I wish you the best of luck with it. I hope it works for you.
Avatar n tn my husband just started on Namenda, starter doses, however, while I was at work today, he took 3 of the pills(5mg), should I be concerned? do I just have him continue tomorrow with the correct one pill in the morning? doesn''t seem to have any side effects.
Avatar f tn Hi, I have GAD and took lexapro and generic lexapro for almost 9 years before it stopped working for me. My doc put me on effexor xr on May 5 and I feel as though my anxiety has gotten worse. She has recommended we double the dose to 150 mgs . I am looking for advice as to whether I should continue on this path. I want so much for this to work ! Any thoughts? Thank you so much! Anyone has this experience and then had improvement? Looking for any and all positive feedback!
Avatar n tn I have had migraines since I was 13, and despite every neuro med had either done absolutely nothing for me or I have to go the ER for severe adverse side effects. The last med I tried was Namenda...and another ER visit. Also, what advise can you advise for the Pain Management Clinic, and what questions should I ask...pros and cons, etc.
Avatar m tn It is Wyeth’s hope that Pristiq, therefore, will replace Effexor XR in a few years’ time. Why? Because Effexor XR makes $3.8 billion (with a ‘b’) a year in sales. Pristiq has shown the same level of effectiveness as many other antidepressants on the market today — about a 2 point difference in a depression rating scale, compared with a placebo.
Avatar n tn As Leftcoast said Effexor and Pristiq are 99% the exact same medication with a slightly different release mechinism. In fact the molecular structure of the two drugs is almost identical. BUT, that does not supprise me that you still got Effexor withdrawls during the switch. Our brains and bodys can sense even the slightest variation with drugs.
Avatar f tn I've been on Pristiq. My GP gave it to me. I've been on it for about 6 months and it's fine for me. It's most effective dose is 50mg, which is equivalant to 150mg Effexor XR I was told. My psychiatrist switched me to Effexor because he says they are the same and I am tapering off. I did NOT gain weight on Pristiq and I think the sexual side effects weren't as bad. I can tell the difference on Effexor.
Avatar f tn My neighbors doctor prescribed fluoxetine and namenda before MRI being done.test came back no signs of alzheimers disease. Should she continue to take ? She is 80 years old somewhat forgetful nothing to make you say you can't function she is 80.
Avatar f tn Hey Linz, my psych had switched me to Vyvanse when it first came out, and at my next appointment I asked to be switched back to Adderral XR. The vyvanse did not work much at all for me, if anything it made me worse. So now I'm back on Adderral, and doing alright, or as alright as I can be doing (unfortunately meds don't make everything ok).
Avatar n tn My doctor prescribed me Effexor XR and I got my prescription filled but before taking it I decided to do some research about this drug. The withdral and side affects scared me so I decided agains this drug. Then doctor priscribed me Citalopram and I've been taking it since. I have been taking citalopram 20mg a day for about 3 months. At the time of my visits to the doctor I had an insurance that covered my drugs, now I don't have my insurance any longer.
Avatar n tn He is on Namenda and Plavix, is it possible that Adderall could help with his short term memory loss. Before the accident he lived on his own.
5717070 tn?1376586671 BUT, my insurance (Aetna) has denied it. Oh well... They put me on Namenda XR - is usually given to patients with moderate to severe Alzheimer's.
603543 tn?1255294450 I hate to see you have to switch from Effexor XR if it was working well for you. You are correct that Celexa and Effexor XR are very different in terms of what neurotransmitters they effect in the brain. Celexa being an SSRI and Effexor XR being an SNRI. For depression has heavy symptoms of fatuge and exhaustion, then an SNRI is always a better bet becuase they tend to be more energizing.
Avatar n tn What could be causing me to have all of them. I am under pretty good control as I take neurontin and namenda. Before I was put on namenda i was having rhizotomies almost every three months due to the excruciating pain.
Avatar f tn Pristiq is kind of a funny SNRI. Remember it was released just before Effexor XR ended it's 7 year patent protection. Effexor and Pristiq are 99% the same drug in terms of active chemical. Pristiq being Desvenlafaxine and Effexor being Venlafaxine. In fact if you look at the molecular chart for the two drugs they even bind the same. Funny thing is you know why Weith pharm released Pristiq?
Avatar n tn Yes, a PFO can cause fatigue as the blood/oxygen level pumped into circulation may be compromised. More likely, the cause of being tired can be related to low blood sugar and anemia.
Avatar f tn I, like many of you, take handfuls of drugs just to live thru the day and suffer side effects from the drugs is just as debilitating as the pain. My doctor allowed me to try Namenda, which is a alzheimer drug that works by calming overactive neurons in the brain. There has been studies to see if it helped chronic pain and most of them showed it did not. I wanted to try it for myself and she allowed me too. My shrink also thought it was a good idea to try.
Avatar f tn Desvenlafaxine succinate, marketed under the name Pristiq, is an antidepressant of the serotonin-norepinephrine reuptake inhibitor class from Wyeth (the makers of Effexor). It is a metabolite of venlafaxine (Effexor). It is said to have less side effects than Effexor and better absorbed according to my doctor,but clinical trials and any reserach I have done do not state that. It seems that they are prety much the same.
585414 tn?1288941302 Yes I am somewhat familiar with that. For example Namenda which is used to treat dementia is in clinical study as a mood stabilizer and to treat tardive dyskinesia. However as those medications specifically effect those receptors by mitigating their activity they work in an opposite manner to glycine and the NMDA receptor modulates.
