Pristiq Side Effects

What are Pristiq side effects?

Side effects are physical, mental or emotional symptoms which occur in addition to or outside of the desired effect of a therapeutic treatment such as an over-the-counter or prescribed drug or medication. Side effects from Pristiq may occur at the beginning or at the end of treatment and may also depend on the length of time an individual remains on the treatment. Side effects, also known as adverse effects, are generally more likely to occur when starting treatment. Individuals may also experience side effects from Pristiq as a result of an interaction with other medications.

Side Effects of Pristiq

The side effects of Pristiq may vary in number and intensity for many different reasons. Factors such as age, weight, gender and ethnicity may influence the side effects of Pristiq. Also, an individual’s state of general physical health and seriousness of the disease or illness as well as an increase or decrease in dosage may lead to side effects. Further, side effects from Pristiq may also occur as a result of an interaction with certain herbal supplements, foods or drinks.

Prescription drug side effects can be serious and may cause patients to stop the treatment. However, when side effects from the use of a prescription drug, such as Pristiq, do occur a patient should consult their physician. A physician may prescribe an additional treatment in order to control the symptoms or an adjustment in the dosage may be made. In addition, changes to diet, exercise or other lifestyle activities may help to lessen the side effects of Pristiq.
