Common Questions and Answers about Pristiq mechanism of action

pristiq

Avatar f tn It's hard to say WHY you had panic attacks. It could have been part of a discontinuation symptom from d/c'ing the Paxil (like a w/d), because while you were started on a new med (Zoloft) while coming off the Paxil, they aren't identical in their mechanism of action, and you could still experience some w/d. Paxil is notoriously hard to come off of. What was the dose you were at when you stopped taking it and what was the dose of Zoloft?
Avatar m tn I am not physically restricted - I walk 1 mile or more day and do 10 minutes of other light exercises most days. My BP runs under 120/80 most of the time. I understand carvedilol helps prevent stiffening of the heart muscle and can help restore LV function to some degree. How specially, so it do this? What is the biochemical mechanism?
Avatar n tn This mechanism would account for the increase in levels of medications that are metabolized by CYP3A when concomitantly administered with grapefruit juice. A list of medications that have been shown, in clinical studies, to have an interaction with grapefruit juice can be found in the table below. All of the medications, except for theophylline and itraconazole, are known to be substrates of CYP3A. When given with grapefruit juice in pharmacokinetic studies their availability increases.
Avatar f tn Abilify can be used to augment antidepressants such as Lexapro. I use Lamictal to augment my Pristiq and it works much better than just the Antidepressant alone. Combining SSRI's or SNRI's with mood stabilizing drugs such as Abilify or Lamictal can often help a lot. Although they do take a good few weeks to kick in. In the past I have taken just about every drug you mentioned above, but I am supprised that your doctor has never tried you on an SNRI such as Effexor XR or Pristiq.
Avatar m tn The mechanism of action of CampralĀ® (acamprosate calcium) Delayed-Release Tablets in maintenance of alcohol abstinence is not completely understood. Originally, several neurotransmitter systems, including GABA, were investigated for a possible role in Campral's mechanism of action. However, recent evidence suggests Campral's main interaction is with the glutamate system. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition.

Avatar m tn Oyakawa I am in my 3rd year of medical school and I was wondering the mechanism of action of steroid injections in the eyelid causing cataracts. It is not an osmotic agent so why does that occur? thanks so much.
382218 tn?1341181487 Thanks for posting this DV. My favorite part was the mechanism of action for Tecfidera. "Poorly understood...
Avatar n tn Maybe you should ask for another AD that you have heard of. If you are afraid to take the Pristiq, but want to feel energetic and happy again, maybe you should go on Celexa or Zoloft or something?
603543 tn?1255294450 i have been on Pristiq for 8 months now and i also take Wellbutrin. 50mg of the Pristiq and 400mg of the Wellbutrin. Only been on the Wellbutrin for a few months. For the most part i thought i was doing alright. But now i havent gotten hardly any sleep in a week. I missed a couple doses and i wonder if this is why. I also have a constant headache. I take mine at night and then just 200mg Wellbutrin in the morning. i wonder should i try and take it at another time? As for the sex drive...
Avatar f tn s important to note that while all SSRIs are in the same class, they are NOT all the same. They actually all vary quite a bit in their exact make up and mechanism of action...therefore, just because you did poorly on one doesn't mean you would do poorly on another (and vice versa). My personal (unofficial) recommendation would be to try either Lexapro or Prozac.
Avatar f tn Plavix has a unique mechanism of action by blocking the amplification of platelet activation by released ADP, and often used with aspirin to prevent the risk of clots for the first year after DES implant. Plavix and aspirin have different mechanism of action to prevent clots. After a year, plavix is usually discontinue as the risk for clots is decreased, and aspirin is continued long term. The risk of a clot is about 3%.
Avatar f tn Desvenlafaxine ( Pristiq ) is a novel form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). It works by blocking the transporter "reuptake" proteins for key neurotransmitters affecting mood, thereby leaving more active neurotransmitters in the synapse. The neurotransmitters affected are serotonin (5-hydroxytryptamine) and norepinephrine (noradrenaline).
1450085 tn?1298941702 hey everyone, today my psychiatrist switched me from 50mg of Pristiq to 37.5mg of Effexor XR, he said the 50mg of Pristiq was too much, anyone ever done this switch or have experiences on the 37.5mg of Effexor?
Avatar f tn I am trying to come off of Pristiq slowly tapering! I just feel so sick!!!!!!!!!!!!!!! It's a nightmare I want to just cry i'm miserable! I have heart palpitations I'm very nauseas anyone else get this way? How long will this take to go away I can't go on like this. I am doing 50mg every other day i'mg oing to do this for a few weeks then try and break them in half being that 50 is the lowest dose. I want to feel better. It is also making me think crazy things...

606378 tn?1297304964 I was on a higher than normal dosage of Pristiq for about 8 months. Even at 100Mgs a day (that's high for Pristiq) I never did get full relief from my depression or anxiety. Granted my depression is severe, but this Pristiq just failed to help it. It's called Panvenlafaxine (kind of a sister drug to Effexor) and the two drugs have much the same structure. At one time Effexor at high dosage did help me a lot, but this Pristiq never did a damn thing to help me.
Avatar f tn re not metabolizing the Cymbalta as well as you did the Pristiq you might be missing the artificial stimulation of adrenalin you get from this class of drugs.
Avatar f tn Potassium is a chemical element and it is part of the electrolyte that should be in balance with other lytes to adequately conduct an electrical impulse that originates with the sinus node in the right atrium. The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses.
Avatar m tn n pristiq before bed...I suddenly stopped taking pristiq cuz I ran out n my phyciatrist doc office was closed..its beeen 2days now that I haven't taken pristiq..my head hurts bad it feels soar n my neck n ears hurt n eyes a bit..I also have a soar throat..could this b cuz im just stressing n stressing or because I stopped my medication pristiq?? I would like help plzz..im scared..
6726276 tn?1421126668 m now on Pristiq which is Effexor metabolite. Pristiq is less side effects. Both may work differently. For me, Pristiq work better. Pristiq may also reduce sexual desire but not like Effexor. Also, it work differently from one to another. Google on Pristiq if it available where you live.
Avatar f tn Pristiq is nothing but an active metabolite of Effexor (venlafaxine being Effexor and desvenlafaxine being Pristiq). Honestly, it should be about as effective as Effexor is. The only reason it was created is because Effexor's patent (if it hasn't already) and soon will be a generic, cheap drug. The pharmaceutical companies always come up with a new drug to push over the old ones whenever this happens because they don't make even a quarter of the money off of the generic drugs.
Avatar n tn thanks but my dr says i have no choice but to stay on pristiq due to the side effects ,because of the anyurisms ,1 of the side effects are head aches which could cause the anyurisms to burst .
Avatar f tn ve recently been experiencing panic attacks. My Dr added Pristiq to my treatment. As I understand, Pristiq is a more purified form of Effexor. Since starting on the Pristiq two weeks ago, I have felt like pure poo poo. I went to a GP today, thinking I may have a virus or something. She said she would NEVER prescribe both Effexor and Pristiq together. I'm pretty confused on which doctor I'm supposed to believe. I'm going to try to stop the Pristiq, but am not sure what will happen.
Avatar n tn I went to my psychiatrist today and told him of my episode of missing effexor dose and he said that it was from the effexor, I was just 7 hours late and wound up in ER from symtoms listed in my first post. So he wants me to switch to pristiq, which I have never taken. I am supposed to start taking pristiq 50mg. along with effexor xr 75mg for a week and then effexor xr 37.5mg along with the pristiq for a week, and then just pristiq. I am afraid, seeing how just being off effexor for 7 hrs.
