Venlafaxine is a medication that can be ordered by prescription only. Belonging to a family of antidepressant drugs named selected serotonin and norepinephrine reuptake inhibitors (SSNRIs), Venlafaxine operates by encouraging the brain’s production of the naturally positive, mood-enhancing chemicals serotonin and noradrenaline. Available in either oral tablets or capsules, Venlafaxine is used to treat anxiety, manic depression, dysphoric moods, and panic attacks.
Venlafaxine is prescribed for those who suffer from generalized anxiety disorder, dysphoric moods (feelings of discontent, disassociation, or indifference to the world around them), depression, and social anxiety disorder - psychiatric disorders that interfere with day-to-day living and working.
Venlafaxine has also been used for women who are being treated for breast cancer or to ease ‘hot flashes’ (sudden and extreme changes in body temperature and sweating), which many women experience during the menopause. It can also be prescribed for severe premenstrual cycle depression, OCD, and PTSD.
Venlafaxine increases and supports levels of serotonin, norepinephrine, and dopamine in the brain. Serotonin is created by your nerve cells, but can also created in different parts of the body, including the stomach. Serotonin enables us to experience happiness and helps us to sleep, heal our wounds, and regulate anxiety.
Venlafaxine not only encourages the body to create more serotonin, norepinephrine, and dopamine, but it also protects them by blocking transport proteins from breaking down or reabsorbing these chemicals. In doing so, this keeps a higher level of these chemicals available to the brain. This is important, as it helps us to remain mentally balanced.
Take Venlafaxine exactly as your doctor or healthcare provider has directed. Do not increase or suddenly decrease your prescribed daily dose. Venlafaxine is typically taken two or three times a day with food. If you are taking an extended-release capsule, this is taken once a day, either in the morning or evening with a meal.
You should try to take your tablet at the same time every day. You should not chew, crush, split or try to dissolve your tablet in water; it should only ever be swallowed.
The average afterlife of venlafaxine in the body is slightly less than two days, which is very short. Of course, how long it takes to leave your system entirely is different for every person and dependent on various individual factors, specifically liver functionality, body composition, genetics, and age.
Unlike other anti-depressants, the half-life (the amount of time the body takes to break down half a dose) of Venlafaxine is five hours, give or take. In the case of venlafaxine, the body can break it down very quickly, which means that withdrawal symptoms from the drug may be experienced if just one dose is missed.
You should seek immediate medical help if you believe you have had an allergic reaction to Venlafaxine. Symptoms of an allergy can be difficulty breathing; a rash or sudden hives; or swelling of the mouth, throat tongue, or lips. Allergic reactions can be fatal so do not ignore them or wait for symptoms to pass.
Many medications provoke an adverse response from the body. Some can be serious, though many are minor and will improve gradually as the body adjusts in the initial stages of treatment.
Common side effects of venlafaxine reported in 1 in 100 people are as follows:
If any of the above really bother you, speak to your doctor or pharmacist.
It is also important for patients taking venlafaxine to be aware of serotonin syndrome, which has the following symptoms:
*As every individual’s experience of the drug is different, venlafaxine may cause other adverse effects that may be specific to you. Keep in contact with your doctor while taking your prescription and report anything unusual that you experience.
*Children can be especially sensitive to this drug,Aand side effects such as weight loss may be quite obvious. Venlafaxine may also inhibit their growth/ height.
*Older adults can be especially sensitive to certain side effects of the drug, especially dizziness when standing and bleeding. They are also more likely to experience a salt imbalance, which can in turn increase the risk of falling.
Most adults can take venlafaxine; however, some conditions must be discussed with your doctor before embarking on a course of treatment.
For those who suffer from diabetes, increased vigilance is required because venlafaxine can alter your blood sugar levels, making it more difficult to remain stable. It is thus suggested that for the few first weeks of venlafaxine treatment, patients monitor their blood sugar levels so that if adjustments to their treatment are necessary, they can be identified as soon as possible.
Some drugs can interact and have strong reactions to one another. Sometimes this means we are more vulnerable to the side effects of certain drugs, or the intensity of the side effects can be dangerous or even life-threatening. You must never start, stop, change, or up your doses without your doctor’s go-ahead.
A potentially fatal drug interaction can be caused by taking MAO inhibitors alongside venlafaxine. Generally, MAO inhibitors should not be taken two weeks before or at least seven days after treatment with venlafaxine. MAO inhibitors include isocarboxazid, linezolid, methylene blue, metaxalone, moclobemide, phenelzine, rasagiline, procarbazine, safinamide, tranylcypromine, and selegiline.
Venlafaxine is extremely similar to desvenflaxine. If you are using one already, DO NOT combine with the other.
Aspirin can increase the risk of bleeding when you are taking venlafaxine. However, if your doctor has told you to continue taking a low dose of aspirin to combat the risk of stroke or heart attack, you should continue taking it. But always be sure to discuss this with your doctor or pharmacist first.
The risk of serotonin syndrome increases when you take other drug that increase serotonin creation. Recreational drugs such as MDMA or ecstasy, antidepressants or selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine or paroxetine, or serotonin-norepinephrine reuptake inhibitors (SNRIs), namely duloxetine/ milnacipran, as well as the herb St. John’s Wort can all cause the risk of serotonin syndrome or toxicity to escalate.
The use of opioid pain relievers or cough medication should also be discussed with your doctor when taken alongside venlafaxine. These, amongst other medications such as marijuana, drugs to aid sleep or anxiety, muscle relaxants, or antihistamines, all cause drowsiness and should not be taken with venlafaxine without medical advice.
Check the ingredients of all your current medications/prescriptions or non-prescriptions and discuss with your doctor before embarking on your prescription with venlafaxine. This includes medication for allergies, coughs, or colds.
It is known that taking venlafaxine can cause false positives for amphetamine use when providing urine samples. Bring your prescription for venlafaxine to the attention of healthcare professionals when undergoing tests.
This drug does not require specific storage but should be kept out of the reach and sight of children.
Do not use venlafaxine past its expiry date, as stated on its packaging.
When wishing to dispose of venlafaxine when it is no longer needed, speak to your pharmacist, drugs should not be disposed of in the ordinary household waste.
Seek immediate medical attention.
Symptoms of overdose are trouble breathing, drowsiness, rapid heart rate, collapsing, and/or a seizure. However, symptoms may not be limited to just those reactions.
It can take 4-6 weeks for venlafaxine to start working. However, many patients feel results in 1-2 weeks.
In the early days of taking the drug, mild headaches, dry mouth, dizziness, and sweating are all commonly reported. This is your body adjusting to the drug, and these side effects should go away in 1-2 weeks.
If you decide you want to stop taking venlafaxine, you should not do so without medical instruction and support, as you may quickly experience withdrawal symptoms from the drug.
This is because venlafaxine’s half-life is extremely short in comparison to other antidepressant medications, meaning your body breaks it down and excretes it very quickly through your urine.
This can mean that for patients taking short-life venlafaxine, their withdrawal symptoms can start the same day as their last dose, and for those taking long-life venlafaxine, their withdrawal symptoms can happen in 1-2 days. For this reason, it is better to wean yourself off the drug in stages. 
The best way to stop or minimize withdrawal symptoms when stopping venlafaxine is to reduce dosage over time. The recommended time to taper someone off the medication can vary from two weeks to three months, depending on the dosage taken by the patient..
There are natural serotonin boosters in the world around us. If you decide to take medication, there are lots of avenues to explore as an alternative, and they mostly come down to changes in habits and lifestyle.
