Venlafaxine – brand name Effexor – is a serotonin-noradrenaline reuptake inhibitor (SNRI) that is used to treat depression and anxiety alongside their associated disorders. Compared to other antidepressant medications like selective serotonin reuptake inhibitors, venlafaxine is relatively safe. However, it still has some side effects that both the doctor and patient should look out for.
Like any other drug, venlafaxine has side effects. Doctors should weigh these adverse effects against the potential benefit of using the medicine. The adverse outcomes are more particularly pronounced if the patient is allergic to Effexor or if they are on other drugs that can interact with venlafaxine.
Some of the severe adverse results include mania, seizures, serotonin syndrome, suicidal thoughts, and sexual problems, to mention but a few. Read on to find out more about the common side effects of venlafaxine.

Drowsiness can be a particularly disconcerting venlafaxine side effect. The same can be said of the resultant Effexor insomnia and fatigue. This is because it usually happens at the start of taking the drug when the person doesn’t know what exactly to expect from the drug.

Avoiding Side Effects Of Effexor

Before taking venlafaxine, a patient should let the doctor know all the other medications they are taking.
This important because it can help in the prevention of drug interactions. For example, taking Effexor and Wellbutrin together can result in several episodes of seizures.
An abrupt change in the administration of the medication can result in adverse outcomes that present as Effexor withdrawal symptoms. This, therefore, means that the patient should consult a trained medical professional to understand the process of coming off venlafaxine successfully.
First of all, it should be noted that many of the side effects happen when the medication is abused. Abuse can be in the form of snorting Effexor. Others abuse venlafaxine by combining it with drinking and can get Effexor and alcohol blackouts.
To avoid a cocktail of adverse results, venlafaxine should not be abused.
Patients should only use it as instructed by a qualified physician. By ignoring this medical advice, there is a risk of an Effexor XR overdose, resulting in dire consequences to the health.
If a patient cannot stop abusing venlafaxine, they should check into a drug rehab center. Here, they can access effective treatment options to ensure that they avoid the venlafaxine HCl ER side effects.
