Effexor Side Effects & Interactions

Why I take Anxiety Medication (Effexor vs. Zoloft?)

As with other antidepressants, Effexor and generic venlafaxine can potentially cause a range of side effects.

Common side effects of Effexor XR include:

  • Nausea

  • Reduced libido

Some of these side effects may improve on their own over time.

If you experience persistent or severe side effects after starting treatment with Effexor, its important to contact your healthcare provider for assistance.

Although uncommon, Effexor and other antidepressants can potentially cause more severe side effects. Weve discussed these in our full guide to antidepressant side effects.

As an SNRI, Effexor may interact with other medications, including certain medications used to treat depression and/or anxiety.

Medications that may interact with Effexor include other SNRIs, SSRIs, MAOIs, lithium, triptans, linezolid, tramadol and St. Johns wort.

In some cases, these interactions may lead to a severe increase in serotonin levels, referred to as serotonin syndrome.

Make sure to tell your healthcare provider about all medications you use or have recently used before you begin treatment with Effexor for anxiety.

Should I Take Venlafaxine With Food

Regular-release venlafaxine is usually taken two or three times per day with food, while extended-release is usually taken once per day in the morning or evening with food.

It is usually recommended that you take venlafaxine at the same time every day. You should discuss with your doctor the best way of taking venlafaxine and it is important to follow your doctors instructions carefully.

Predictors Of Response To Venlafaxine

A pooled analysis of the four major clinical trials, including a total of 1595 adults with panic disorder, evaluated predictors of clinical outcomes in the short-term treatment of panic disorder . Greater mean symptom severity and female gender were associated with lower proportions of panic-free patients, in both the venlafaxine XR and the placebo treated group. Among patients treated with venlafaxine XR, 69% of those classified as low severity at baseline were panic free at endpoint compared with 51% of patients in the high severity group . Similarly, 65% of men achieved panic-free status compared with 57% of women . For those treated with placebo, significantly more patients in the low severity group , compared with the high severity group , and men compared with women , were panic-free at endpoint.

How Should This Medicine Be Used

Venlafaxine comes as a tablet or extended-release capsule to take by mouth. The tablet is usually taken two or three times a day with food. The extended-release capsule is usually taken once daily in the morning or evening with food. Take venlafaxine at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take venlafaxine exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.

Swallow the extended-release capsule whole do not split, chew, or crush it, or place it in water. If you cannot swallow the extended-release capsule, you may carefully open the capsule and sprinkle the entire contents on a spoonful of applesauce. Swallow this mixture immediately after preparation and then drink a glass of water to make sure that you have swallowed all of the medication.

Your doctor will probably start you on a low dose of venlafaxine and gradually increase your dose, not more often than once every 4 to 7 days. Tell your doctor how you are feeling during your treatment so that your doctor can adjust your dose properly.

What To Do When Ssris Fail: Eight Strategies For Optimizing Treatment Of Panic Disorder

Effexor gives a perfect treat for anxiety and panic ...

University of Michigan Medical School, Ann Arbor, Michigan

Am Fam Physician. 2002 Oct 15 66:1477-1485.

Selective serotonin reuptake inhibitors are the drug of choice for treatment of patients with panic disorder. Most patients have a favorable response to SSRI therapy however, 30 percent will not be able to tolerate these drugs or will have an unfavorable or incomplete response. Strategies to improve management of such patients include optimizing SSRI dosing and ensuring an adequate trial before switching to a different drug. Benzodiazepines should be avoided but, when necessary, may be used for a short duration or may be used long-term in patients for whom other treatments have failed. Slower-onset, longer-acting benzodiazepines are preferred. All patients should be encouraged to try cognitive behavior therapy. Augmentation therapy should be considered in patients who do not have a complete response. Drugs to consider for use in augmentation therapy include benzodiazepines, buspirone, beta blockers, tricyclic antidepressants, and valproate sodium.

Drug Interactions Of Effexor Vs Lexapro

Effexor and Lexapro each work by increasing available serotonin. When one of these drugs is combined with other drugs that have serotonergic activity, it increases the chance that a patient may experience serotonin syndrome. Serotonin syndrome is a condition caused by having too much free serotonin and can lead to increased blood pressure and heart rate, agitation, and dizziness. Drugs with serotonergic activity include the pain medication tramadol and a supplement often used by patients for mood, St. Johnâs Wort. Other classes of medication may interact in this manner as well, so it is important for your doctor and pharmacist to have a complete list of medications you are taking.

Ondansetron, when taken with Effexor or Lexapro, may increase the incidence of QT prolongation and a type of arrhythmia known as torsades de pointes . Each of these drugs carries a risk for these cardiac events, but their combined use increases the risk significantly. These cardiac events can be fatal in some cases, and the combination of these drugs with Ondansetron should be avoided when possible.

This is not intended to be a complete list of potential drug interactions. Consult your doctor or pharmacist for a complete list.


How To Take Venlafaxine

  • Before you start the treatment, read the manufacturer’s printed information leaflet from inside the pack. It will give you more information about venlafaxine and it will provide you with a full list of the side-effects which you may experience from taking it.
  • Take venlafaxine exactly as your doctor tells you to. Depending upon the brand of tablet/capsule that you are prescribed, you will be asked to take either one or two doses a day.
  • Try to take your doses at the same time of day each day, as this will help you to remember to take them. Have a drink of water to help you swallow the tablet/capsule.
  • If you have been supplied with a modified-release form of venlafaxine , take the tablet/capsule just after a meal. You should swallow the tablets/capsules whole – do not chew or crush them. Modified-release tablets and capsules release venlafaxine slowly over 24 hours to give a longer action.
  • If you forget to take a dose, take it as soon as you remember. If when you remember, it is nearly time for your next dose then leave out the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

    Overview Of Pharmacological Treatment Of Panic Disorder

    Pharmacologic treatment, often in combination with cognitive-behavioral therapies, can be tailored for the individual patient based on specific anxiety symptoms, comorbid disorders, and history of side effects .

    Pharmacotherapeutic interventions that have demonstrated efficacy in treating panic disorder include selective serotonin reuptake inhibitors , the serotonin and norepinephrine reuptake inhibitor venlafaxine XR, tricyclic antidepressants , and benzodiazepines. Current published guidelines from Canada, the United Kingdom, Singapore, and Australia and New Zealand generally recommend antidepressants as first line therapy for the treatment of panic disorder . SSRIs and TCAs have demonstrated equivalent efficacy, but most guidelines suggest that TCAs are less well tolerated. Generally, antidepressants are preferred over benzodiazepines as first line treatment because, unlike benzodiazepines, antidepressants treat comorbid depression without risk of dependency and the potential for side effects such as excessive sedation, cognitive impairment, and ataxia.
