Warnings
If you have an allergy to venlafaxine or desvenlafaxine (Pristiq), or if you are receiving treatment with methylene blue injection, you should avoid taking Effexor.
After taking an MAO inhibitor for two weeks, avoid taking Effexor. There may be a harmful drug interaction. Isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine are examples of MAO inhibitors.
If you have untreated or uncontrolled narrow-angle glaucoma, you shouldn't take Effexor.
Pregnancy-related use of Effexor may result in the baby having serious lung issues or other issues. If you are pregnant or intend to become pregnant, let your doctor know.
Because Effexor may enter breast milk and have negative effects on a nursing infant, it is not recommended that you breastfeed while taking it.
Your blood pressure may go up if you take Effexor. Regularly check your blood pressure.
