Pristiq (the one I take - I have previously tried effexor) is desvenlafaxine, a modified version of effexor. I maintain a small baseline dose, which I jack up during difficult periods, rather than coming off it completely each time.
It's very individual how these meds work, tinkering with the dose makes a lot of sense to me. I hope it works out well when all the moving factors are taken into account.
Sideways, may I ask what dosage is your small baseline dose? I have been on Pristiq since I developed PTSD 15 years ago, after years of depression and anxiety. ( I see my other posts on Pristiq say 8 years. I dont have the brain space to work out ho long its been. You understand.)
My baseline dose is 100mg and I go up to 200mg a day when I am under prolonged stress. I have been on that dose now for over a year and its one I have often needed to be on as I have dealt with ongoing family issues.
If I have an unusual stressor come into my life, I add a night-time dose of 100mg for 2-3 days. This stops the slide into a deep hole for me.
I was recently told by a one-off Psych consult that 100mg is the "Therapeutic dose" and that anything over that does not have any effect. I have proven that to be incorrect multiple times.
I did go onto a trial of Effexor for three weeks but found that my melancholic crying returned quickly. I dont have that with Pristiq and I changed back from Effexor to Pristiq with no ill effects.
I have done several trials of other meds over the years but always come back to100-200mg per day AM Pristiq with 7.5 mg - 15mg Serepax at night before bed. This regime seems to suit me best. I do have issues at times with my GP being Hypervigilant in case of dependence on Serepax, which is so annoying and adds to my stress.
I was offered Mertazipine by the same Psych, to take at night for sleep, but he failed to mention that is the worst med for rapid weight gain, which I knew from my own studies, so I refused his offer.
Glad to see Pristiq is useful for you too.
