Our pharmacists’ bottom line
Pristiq (Desvenlafaxine) is basically the same medication as Effexor, which is cheaper because it's available as a generic.
- Effective at relieving symptoms and lowering relapse rates for depression.
- Six out of ten people who use an antidepressant for the first time find that it works for them.
- Similar to Effexor, without any extra benefits in clinical studies.
- Can cause sexual side effects (usually low libido or the inability to have an orgasm or ejaculate).
- Not available in generic form, so it's more expensive.
- Like most antidepressants, can cause higher risk of suicidal thoughts and behavior for people age 24 and younger.
- The first antidepressant you try doesn't always work or it can cause side effects you really don't like. You might need to try a few different medications until you find one that works for you.
