Effexor XR (Generic Venlafaxine)
Actual product appearance may differ slightly.
A tiny percentage of youngsters, teenagers, and young adults (up to 24 years old) who took mood-elevating antidepressants like venlafaxine during clinical research developed suicidal thoughts (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 diseases may have a higher risk of committing suicide than those who do not take these medications. However, experts disagree on how significant this risk is and how much it has to be taken into account when determining whether or not a kid or adolescent should take an antidepressant. Venlafaxine is typically not recommended for use in people under the age of 18, although in some circumstances, a doctor may determine that it is the best treatment option for a child’s illness.
Even though you are an adult over the age of 24, you should be aware that taking venlafaxine or other antidepressants may cause your mental health to change in unforeseen ways. In particular, during the start of treatment and whenever your dose is changed, you run the risk of developing suicidal thoughts. If any of the following signs appear, you, your family, or your caretaker should contact your doctor straight away: Extreme worry, agitation, panic attacks, trouble falling or staying asleep, aggressive behaviour, irritability, acting without thinking, severe restlessness, and frenetic excessive excitement are just a few symptoms of depression that may be new or developing. Make sure your family or carer is aware of any symptoms that could be significant so they can contact the doctor on your behalf if you are unable to call for help.
If you are taking venlafaxine, your doctor will want to visit you frequently, especially at the start of your treatment. Make sure to show up for all of your doctor’s appointment times.
When you start your venlafaxine treatment, your doctor or chemist will give you the manufacturer’s patient information leaflet (Medication Guide). If you have any questions, carefully read the information and ask your doctor or chemist. The FDA website also offers the Medication Guide.
No of your age, you, your parent, or your carer should discuss the advantages and disadvantages of treating your disease with an antidepressant or with alternative treatments with your doctor before starting an antidepressant. The dangers and advantages of not treating your ailment should also be discussed. You should be aware that your chance of committing suicide is significantly increased if you suffer from depression or any mental disorder. This risk is increased if you or a family member currently has, or previously had, bipolar disorder (depression followed by periods of extreme excitement) or mania (frenzied, abnormally excited mood), or if you have ever considered or tried suicide. Discuss your ailment, symptoms, and personal and family medical history with your doctor. The best course of therapy for you will be decided by you and your doctor.
Why is this medication prescribed?
Utilized to treat depression is venlafaxine. In addition to treating panic disorder, venlafaxine extended-release (long-acting) capsules are also used to treat social anxiety disorder, generalised anxiety disorder, and panic disorder. Generalized anxiety disorder (GAD) is characterised by extreme fear of social interaction and performing in front of others (sudden, unexpected attacks of extreme fear and worry about these attacks). The drug Venlafaxine belongs to the group of drugs known as selective serotonin and norepinephrine reuptake inhibitors (SNRIs). It functions by raising the brain’s natural levels of serotonin and norepinephrine, which support mental equilibrium.
How should this medicine be used?
Venlafaxine is available as a tablet or oral extended-release capsule. The tablet is often taken with food two or three times per day. The extended-release capsule is typically taken once daily, with or without food, in the morning or evening. Take venlafaxine every day at around the same time(s). Ask your doctor or chemist to explain any instructions on your prescription label that you are unsure about following. Venlafaxine should be taken as prescribed. Never take it in larger or less amounts, or for longer periods of time than your doctor has advised.
Do not split, chew, or crush the extended-release capsule, or submerge it in water. Instead, swallow it whole. You can carefully open the extended-release capsule and sprinkle the entire contents on a spoonful of applesauce if you are unable to take it. After preparing the mixture, immediately ingest it (without chewing) and follow that with a glass of water to ensure that you have consumed all of the drug.
Your doctor would likely prescribe you a modest dose of venlafaxine to begin with and gradually raise it, no more frequently than once every 4 to 7 days. In order to correctly modify your dose, tell your doctor how you are feeling throughout your therapy.
Although it doesn’t treat depression, venlafaxine can manage it. You could need a few weeks or longer to experience the full benefits of this medicine. Despite feeling fine, keep taking venlafaxine. Without first seeing your doctor, do not discontinue taking venlafaxine. Most likely, your dosage will be gradually reduced by your doctor. You could have withdrawal symptoms such agitation, anxiety, fatigue, disorientation, mood swings, headaches, and dizziness if you stop taking venlafaxine abruptly; agitation, mania or unusual excitement, lack of coordination, sleep issues (including nightmares), nausea, vomiting, loss of appetite, diarrhoea, dry mouth, and perspiration; erratic shaking of a body part; ringing in the ears; dizziness; convulsions; or burning, tingling, numbness, or electric shock-like sensations in any body part. If you encounter any of these signs while lowering your venlafaxine dosage or soon after stopping the medication, let your doctor know.
Other uses for this medicine
In some cases, venlafaxine is also used to treat hot flashes (also known as hot flushes, which are sudden, intense feelings of heat and perspiration in females) in menopausal (also known as “change of life” or “the end of monthly menstrual periods”) or breast cancer patients. Regarding the dangers of using venlafaxine to treat your disease, see your doctor or chemist.
Ask your doctor or chemist for more details if you’re interested in using this medication for any other conditions.
What special precautions should I follow?
Before taking venlafaxine,
- If you have any allergies, including to any of the chemicals in venlafaxine tablets or extended-release capsules, tell your doctor and chemist very away. Get a list of the ingredients from your chemist.
- You should be aware that another SNRI, desvenlafaxine, is quite similar to desvenlafaxine (Pristiq). These drugs should not be taken at the same time.
- If you are currently taking an MAO inhibitor, such as isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate), or if you have stopped taking one of these drugs within the previous 14 days, let your doctor know. You should not use venlafaxine, your doctor will likely advise. In the event that you stop taking venlafaxine, your doctor will advise you to wait at least 7 days before starting an MAO inhibitor.

A recent heart attack, high blood pressure, high cholesterol, seizures, glaucoma (increased pressure in the eye that may result in blindness), heart, kidney, liver, or thyroid problems are some things to mention to your doctor.
- If you are pregnant, particularly if you are in the last few months of your pregnancy, if you plan to get pregnant, or if you are breast-feeding, let your doctor know. Call your doctor if you get pregnant while taking venlafaxine. If venlafaxine is taken in the final months of pregnancy, it may have negative effects on babies after birth.

- You should be aware that this medication may cause drowsiness and may impair your thinking, judgement, and motor skills. Prior to understanding how this drug affects you, avoid using machinery or driving a car.
- Be in mind that drinking can increase the drowsiness this drug causes.
- It’s important to be aware that venlafaxine may raise blood pressure. Before beginning treatment and periodically while using this drug, you should have your blood pressure tested.
- It’s important to be aware that venlafaxine may result in 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). Ask your doctor if you should get your eyes checked before beginning this medicine. Call your doctor or get emergency medical attention right away if you are experiencing nausea, eye pain, changes in your vision, such as seeing coloured rings around lights, or swelling or redness in or around your eyes.

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).
Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
