Bad Side Effects of Effexor

Effexor is a prescription medication used to treat anxiety disorders and depression. Effexor works by altering the levels of norepinephrine and serotonin, which are chemicals that occur naturally within the brain. The antidepressant is intended to fix an imbalance of the chemicals. As with any prescription medication, there are some possible side effects that are associated with taking Effexor.

Common Side Effects

• Common side effects linked to Effexor include sleeplessness, anxiety, dry mouth, excessive sweating, dizziness, nausea, constipation and loss of appetite.

Blood Pressure

• In some individuals, Effexor has been cited to elevate blood pressure. It is therefore crucial for patients to inform their doctors before taking Effexor if they have a history of hypertension. Also, while taking Effexor, it is recommended that patients occasionally monitor their blood pressure levels.

Sexual Side Effects

• Some males might experience various sexual side effects from taking Effexor, the most common being delayed ejaculation. Also, in rare cases, Effexor has been cited to lower sexual desire.

Weight Fluctuation

• Weight gain is another possible side effect that is occasionally linked to Effexor, although it is relatively rare. Some patients have also reported experiencing weight loss from the medication.

Severe Side Effects

• Severe side effects that require immediate medical attention include bleeding or bruising, feelings of unsteadiness, lack of coordination, extreme blistering, skin rash and peeling, difficulty concentrating, problems with memory, disorientation, confusion, weakness, fainting, hallucinations, seizure and difficult or shallow breathing.

Contraindications

• People taking the antidepressant monoamine oxidase inhibitor (MAOI) are advised against taking Effexor simultaneously. People taking MAOI should cease use of it a minimum of 2 weeks before starting with Effexor, and vice versa.
