Venlafaxine Hydrochloride Information
(ven' la fax een)A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as venlafaxine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take venlafaxine, but in some cases, a doctor may decide that venlafaxine is the best medication to treat a child's condition. You should know that your mental health may change in unexpected ways when you take venlafaxine or other antidepressants even if you are an adult over 24 years of age. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own. Your healthcare provider will want to see you often while you are taking venlafaxine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor. No matter your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.
Before taking venlafaxine,
- tell your doctor and pharmacist if you are allergic to venlafaxine, any other medications, or any of the ingredients in venlafaxine tablets or extended-release capsules. Ask your pharmacist for a list of the ingredients.
- tell your doctor if you are taking a monoamine oxidase (MAO) inhibitor, such as isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or if you have stopped taking one of these medications within the past 14 days. Your doctor will probably tell you that you should not take venlafaxine. If you stop taking venlafaxine, your doctor will tell you that you should wait at least 7 days before you start to take an MAO inhibitor.
- tell your doctor and pharmacist what other prescription and nonprescription medications, and vitamins you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin); amiodarone (Cordarone, Pacerone); other antidepressants; cimetidine (Tagamet); clozapine (Clozaril); diuretics ('water pills'); duloxetine (Cymbalta); haloperidol (Haldol); imipramine (Tofranil); indinavir (Crixivan); ketoconazole (Nizoral); linezolid (Zyvox); lithium; medications for anxiety, mental illness, pain, seizures, or weight loss; medications for migraine such as almotriptan (Axert), eletriptan (Relpax), frovatriptan (Frova), naratriptan (Amerge), rizatriptan (Maxalt), sumatriptan (Imitrex), and zolmitriptan (Zomig); methadone (Dolophine); methylene blue; phentermine (Adipex P, Ionamin); ritonavir (Norvir); sedatives; selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft); sibutramine (Meridia); sleeping pills; tramadol (Ultram); and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor what nutritional supplements and herbal products you are taking, especially St. John's wort and tryptophan.
- tell your doctor if you have ever used illegal drugs or overused prescription medications. Also tell your doctor if you have recently had a heart attack and if you have or have ever had high blood pressure, high blood cholesterol seizures, or heart, kidney, liver, or thyroid disease.
- tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking venlafaxine, call your doctor. Venlafaxine may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking venlafaxine.
- you should know that this medication may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- remember that alcohol can add to the drowsiness caused by this medication.
- you should know that venlafaxine may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
