Prozac upped to 40mg from 20mg

Posted , 3 users are following.

Hi all just wondering if anyone has experience upping their dose of prozac from 20mg to 40mg and whether or not they experienced any side effects? I am 5 days in on 40mg and feeling all the horrible side effects again. This is extremely difficult to manage and wanted to know if anyone else had a similar experience and how they managed and how long it took for the 40mg to start working and settle down.

      Thanks for replying. I am getting all the same side effects I got when first starting on the meds at 20mg. Heightened anxiety, dizziness, blurred vision, irritable and feeling weird. I was on 20mgs for 2 weeks before upping the dose as the Dr's advise.

      I might try the split dose but I moved from taking a dose in the morning to avoid the day time fatigue and nausea originally.

      Hi roseywosey,  Overall it sounds like your still within 4-6 weeks (total) from first taking Prozac?  It’s common during that period to have a rough time with side effects.  I hope it clears up soon for you.

      Yes its only been 3 weeks and 2 days total. I am going to go back down to 20mg per day for now and get to 6 weeks before deciding on whether or not to go higher. If I do, I am going to go super slow, maybe 25mg for 2 weeks, 30mg for another 2 weeks then the full 40mg thereafter. I have 20mg tablets that I can split and also a pill cutter to split the 10's into 5's.

      I hope dropping to 20mg makes things more comfortable for you.  Let me know how that goes ok. I’m on 20mg and fear having to go up.  I “do not” want to experience those side effects again if I can help it.  I was crawling out of my skin!  Be well.
