Katrin: Reinstatement of SNRI After Acute Withdrawal

Featured Replies

Thank you for allowing me to post.

I am having difficulty grasping the technicality of how to post on this forum - formatting, correct place to post etc. So, please forgive me if I'm not doing this correctly.

Reinstatement of Last Dose

I've been experiencing horrible Akathisia symptoms a week after I dropped from 50mg to 45mg. It's been profoundly debilitating. First and only drop on 25th July 2026 - one month ago.

Yesterday I increased by 2.5mg (now 47.5mg total)

I feel somewhat better today (still awful) but the overwhelming depression was intolerable. It seems to have slightly improved on waking today.

Question: Is it possible that the 2.5mg increase yesterday has improved my dark mood in one day? Note: this increase or reinstatement is half of the original taper decrease amount of 5mg.

I'm finding this all very confusing. Thanks for your thoughts.

Edited by SarahMc

CURRENT:

Pristiq 47.5mg (SNRI - slow release) for 20 years (started taper at 50mg June 2026). Initially started at the taper at 45mg which was too much. Reinstated 2.5mg on 28th August.

Zolpidem (Stilnox) 10mg (Z-class) for five (5) years (no taper atm)

Promethizane (antihistamine): in addition to Zolpidem for sleep.

HISTORY:

Tramadol - up to 300mg a day. Stopped abruptly February 2026 - experienced protracted withdrawal. Did not understand this is what I was experiencing until I started to taper off Pristiq and learn about tapering and withdrawal.

  • Author

I have experienced ongoing and debilitating insomnia ever since I started the SNRI - Desvenlafaxine (Pristiq) 20 years ago.

As a result I started taking Stilnox (Zolpidem) five years ago every night.

I've had to include 25mg of antihistamine Promethazine on top of the Zolpidem as that medication alone stopped being effective (I know it's stupid, but I've been desperate.)

Could someone please explain the adverse effects this could be having on my acute withdrawal symptoms? Thank you.

PS: I've searched for the topic but couldn't find anything.

I'm so sorry to read about the tough time you've had recently you will find plenty of support here for sure.

This is the right place for your intro post. We'll generally keep all of your questions about your own experience on this thread.

I'm so sorry to hear this. As you may know, we recommend tapering by a maximum of 10% of your previous dose per month: Tapering Information. Many people need to go more slowly than this. You've been on Pristiq for a very long time and the SNRIs are notoriously hard to come off. Based on your severe reaction to your first 10% cut, it sounds like you may need to taper much more slowly.

It's possible that the 2.5 mg increase helped quickly. It's also possible that this is just the normal ups and downs of withdrawal. Many people experience waves and windows while stabilizing: The Windows and Waves Pattern of Stabilization

If I were you, I would hold at your current dose until your symptoms settle down. This could take a little while. I would then make tiny cuts each month to try to figure out what I could tolerate. You could start at as little as 1% just to see how you react.

In the mean time this is what I would do if I were you:

 

-Stay Hydrated 

 

-Eat a good clean whole food diet, avoiding processed foods and sugars.

 

-Stay away from caffeine, alcohol and antihistamines and any other psychoactive substances.

 

Supplements are to be avoided initially, as they often irritate our nervous systems. Try to get your nutrition through food.

 

Down the line, you may wish to introduce Fish Oil and Magnesium. Those who can tolerate them have found them calming to the nervous system. Be careful try one at a time and start low and see how you get on should you choose to try them.

 

A daily walk is very important as much as you can manage, if you can manage it. Gets you your fresh air and Vitamin D does wonders for your mind!

 

You are very welcome here and I hope you find the site supportive.

Cymbalta - 60 mg/day, periodically down to 30 mg/day - May 2014 to May 2025

Clonazepam - up to 1 mg/day as needed - March to May 2025, quick taper off

Zoloft - 150 mg/day - May 2025 to Aug 2025 (quick cross-taper from Cymbalta)

Pristiq - 50 mg/day from Aug 2025 to mid-Oct 2025 (quick cross-taper from Zoloft); 100 mg/day from Oct 2025 to Dec 2025; back down to 50 mg/day from Dec 2025 to Jan 2026

Hi @Katrin -- I've moved your question about antihistamines to your intro thread.

We generally recommend against using antihistamines in WD because of observations in the community that it can make folks worse. However, like most things about WD, we don't really know why people can react badly to using antihistamines. We do have a thread on this in our Symptoms & Coping Strategies section: https://antidepressantrecovery.org/topic/354-antihistamines-good-or-bad/#comment-23279

Can I ask how long you've been taking promethazine? If it's been a while, it may not be a good idea to stop it cold turkey since you're in quite a sensitive state at the moment.

I'm sorry this has been such a rough journey for you. Glad you found us.

Thank you, Sarah. I will reduce the amount of Promethazine as I've been using it regularly for 20 years! I'm between a rock and a hard place. PS: I'm finding navigating and using this forum very confusing. Is it just me?

CURRENT:

Pristiq 47.5mg (SNRI - slow release) for 20 years (started taper at 50mg June 2026). Initially started at the taper at 45mg which was too much. Reinstated 2.5mg on 28th August.

Zolpidem (Stilnox) 10mg (Z-class) for five (5) years (no taper atm)

Promethizane (antihistamine): in addition to Zolpidem for sleep.

HISTORY:

Tramadol - up to 300mg a day. Stopped abruptly February 2026 - experienced protracted withdrawal. Did not understand this is what I was experiencing until I started to taper off Pristiq and learn about tapering and withdrawal.

Hey @Katrin Welcome to the forum. I am so sorry you are having a hard time atm. Glad you found us.

Save this thread page as a favourite in your phone or computer so you get back here easily. As Sarah has said just post on here any questions you have and we can answer them for you. As you get more confident you can go and say hi to others on their pages :)

You can't delete a post, you have 60 mins from making a post to edit it. x

It sounds like to me updosing has eased this for you imo, I think you did the right thing and choose the correct dose to go up by. I would leave things just as they are until everything settles down for you.

As you have been taking Zopidem for a long time you will need to continue to take it every night now, until you are stable enough to taper off it. You have gained alot of dependance on it and WD could be a real issue for you if you try to stop atm. As you have noted you will have built up tolerance to the drug and it won't be helping you sleep anymore unfortunately.

The antihistamine I would also be very cautious with stopped quickly too. I would actually be inclined to keep taking them for a bit until you stablise. Then look to reduce them once things have settled down for you. Wouldn't want you to rock the boat at this stage.

I really very sorry about your sleep, I know how hard this can be. We all do to some extent as sleep is a big issue in WD.

We have a post about it actually which you might like to read. Sleep in WD

Welcome to the forum.

Try not to worry about difficulties using the forum too much, you'll get the hang of it in time. We can help with moving posts and topics if they end up in the wrong place.

Once you have hopefully stabilised, we can share information on alternative tapering methods that you will hopefully find more tolerable, but we can get to that down the line. For now, let's see how you do on this dose for a time.

Nothing I say is medical advice, it is simply my opinion. I am an anonymous person on an internet forum with no relevant qualifications other than being badly harmed by a drug. For all you know, I could be an idiot. You are making your own decisions and part of that is deciding how much to listen to my opinion, if at all.

 

Perhaps you should consider this post an artistic work of fiction written for entertainment purposes.
