  • How Does Effexor Work?

    Effexor works by increasing the overall levels of certain chemicals in the brain, including serotonin. Effexor's process is often beneficial to people with low serotonin and depression. Some people also experience reduced levels of serotonin during a migraine, so by keeping these levels high, Effexor may help prevent migraines from happening in the first place.

  • How Is Effexor Used?

    Currently, only Effexor XR is available for prescription in the United States. Effexor XR is an extended-release capsule or tablet that slowly releases the active ingredient Venlafaxine into the body throughout the day. This medication is taken once a day to prevent migraines. Taking this medication at different times each day may impact how effective the drug is, so be sure to take Effexor at the same time every day if possible.

    When you first start Effexor, you'll likely begin at a low dose and slowly work your way up to a dose that's right for you. Our dedicated healthcare experts will be with you every step of the way to make sure your Effexor dosage is working for you.

    While some people experience results soon after starting Effexor, it could take several months for this medication to decrease the frequency at which you experience migraines. It's important to not give up hope and to continue to take Effexor even if you don't feel its effects immediately.

  • Is Effexor Easy to Get?

    Effexor is a medication that's available in almost any pharmacy. However, Effexor does require a prescription. Luckily, Nurx makes it easier than ever to get the medication you need. Our doctors can prescribe the right medication for you online and you can even choose to have it sent to you in the mail.

    We even accept several different types of insurance, making it more affordable than ever to get your prescription. Even if Effexor isn't covered by your insurance provider, we offer the generic version of Effexor, known as Venlafaxine, to make it less expensive when paying out of pocket.

  • What Precautions Should I Take Before Starting Effexor?

    As with any antidepressant, you should consult with your doctor or one of Nurx's medical professionals before starting Effexor. Discuss any current medications you're taking, including other antidepressants. If you're planning on becoming pregnant or are currently pregnant, Effexor may not be the right option for you. The experts at Nurx can help you find the medication that's best suited for your unique needs.

  • Are There Any Known Side Effects of Effexor?

    Every SNRI, including Effexor, comes with the potential for side effects. Fortunately, most side effects are mild and will dissipate over time as your body acclimates to the drug, and many people find that the positive benefits far outweigh the side effects experienced.

    Common side effects of Effexor include symptoms of indigestion like constipation, heartburn, diarrhea, gas, nausea, and stomach pain. They may also experience headaches, nightmares, drowsiness or tiredness, dry mouth, weakness, loss of appetite and/or weight loss, frequent urination or trouble urinating, and changes in sexual desire.

    More severe side effects are extremely uncommon when taking Effexor. These include suicidal thoughts and behaviors, rash, itching, hives, trouble breathing or swallowing, seizures, eye pain, fever, trouble with coordination, chest pain, irregular or fast heartbeat, and unusual bleeding or bruising.

    Additionally, a condition known as serotonin syndrome can occur when taking Venlafaxine. While very rare, serotonin syndrome is a serious condition caused by too-high levels of serotonin in the body. This is most often seen when the Effexor dosage is increased too quickly or if you add another antidepressant into the mix. Symptoms of serotonin syndrome include confusion, high blood pressure, sweating, headache, diarrhea, and shivering. More severe symptoms include fever, seizures, and unconsciousness.

    If you notice these symptoms, talk to your healthcare provider immediately.

  • Can I Take Effexor With Other Medications?

    Some medications can put you at risk if you take them with Effexor. For example, taking an MAOI and Effexor at the same time can result in serious side effects, so make sure you've been off of an MAOI for at least two weeks before beginning Effexor. You should also inform your doctor if you're taking anticoagulants, other antidepressants, diuretics, other medications used for mental illness, migraine medications, sleeping pills, or nutritional supplements like St. John's wort or tryptophan before beginning Effexor.

  • Who Makes Effexor?

  • Does Effexor Make You Gain Weight?

    While pretty uncommon, Effexor has been associated with weight gain in some people who take it. This is a potential side effect in several antidepressants, but it doesn't mean that everyone who takes it will gain weight. Weight gain as a result of taking Effexor may be caused by lack of exercise, increased appetite, and fluid retention. If you're worried about this potential side effect, not to worry! There are a few things you can do to counteract it, such as ensuring you get regular exercise while taking the drug and avoiding high-calorie foods.

  • Does Effexor Make You Sleepy?

    A lot of antidepressants, including Effexor, come with the potential (and mild) side effect of sleepiness. If you're concerned about fatigue, you can always talk to one of our doctors to decide if Effexor is the right antidepressant option for you.

  • Are There Other Uses for Effexor?

    While Effexor is primarily used to treat depression, anxiety disorders, and panic disorders, it is commonly used off-label for migraine prevention, which is the way that we at Nurx use it. Other off-label uses include for the treatment of hot flashes, ADHD in adults, diabetic neuropathy, and to combat the negative side effects of some medications used to treat breast cancer.
