Common concerns from people taking Pristiq (Desvenlafaxine)Final section. Do you want to return to drug navigation?
- Alcohol definitely has a stronger effect on this medication. I am usually pretty warm compared to before I started this medication and sweating happens relatively easy. Occasionally, I feel jittery, get hot flashes, or have ringing in my ears. I also noticed I yawn more during physical activity.
- Do not miss. Back of your neck hurts and it feels as if little electrical shocks are going up into your brain. Take it at the same time every day. It saved me. Period.
- Definitely take in the morning. I had no drowsiness, but rather felt more alert. I couldn't sleep when taken in the evening. Uptake is practically nonexistent with 50mg being both a starting and therapeutic dose. Took about a week and half for noticeable change. Within a month, great benefit along side psychological talk therapy.
- Although my doctor told me this medication was weight neutral, I gained 20 lbs on it, despite following a 1200 calorie diet and exercising regularly. Detoxing from med included: brain zaps, nausea, migraines, chills, insomnia, panic attacks
- Although this is supposed to be weight neutral I gained 15lbs in 4 months. I was constantly hungry and bloated. Some of this could have been due to the Extreme APATHY I encountered on this medicine. It reduced the extreme anxiety encountered while being unemployed and I can say it did help turn that around, but almost to an extreme point of apathetic procrastination & Fatigue.
