What side effects can i expect taking pristiq (desvenlafaxine)?

Here are a few: Hypertension (up to 2% of people), increased cholesterol levels, constipation, diarrhea, nausea, vomiting, dry mouth, loss of appetite, dizziness, headache, insomnia, feeling too tired, anxiety, sexual dysfunction, withdrawal if you miss a dose. These are among the more common ones and occur in 5-20% of folks on average.

Be awareDon't expect: The list is long and is available from your prescribing professional and your pharmacist. Most commonly experienced are GI symptoms like nausea, diarrhea and abdominal cramping as well as anxiety early on and sometimes insomnia. Being aware they can happen is different than expecting them to happen. Most side effects can be tolerated and eventually ease up. Try to be aware but not expectant.
