What is Vensir?
Vensir is prescribed to treat several conditions related to depression and anxiety, such as OCD (obsessive compulsive disorder), PTSD (post traumatic stress disorder), depression, panic disorders, generalised anxiety and social anxiety. It is marketed by Morningside Healthcare Limited.
How does Vensir work?
Vensir works by stopping the body reintegrating the naturally occurring substances serotonin and norepinephrine, which are naturally occurring, feel-good hormones in the body. This increases their levels in the brain, with serotonin improving mood and norepinephrine improving motivation and social confidence.
Vensir and mental health conditions
Mental health issues are prevalent, with as many as one in four people in the UK reporting serious enough symptoms for them to seek treatment. Depression and anxiety related symptoms present in various ways, and may differ from one person to the next.
While some people may feel low from time to time, depression is experiencing low mood on a continual basis. In certain cases, these symptoms can be as serious as suicidal thoughts or a compulsion to self-harm. In other instances, a sense of hopelessness and a lack of motivation characterise the condition.
Depression can often be triggered by a life event, such as the loss of a family member or partner, or being made redundant. A genetic element may also be a factor in its development, if there is a history of depression or mental illness in the family.
Chronic anxiety, or generalised anxiety, is a life changing condition that can manifest in various forms, both physical and psychological. ‘Chronic’ refers to its ever-presence, and its impact on many aspects of someone’s life. If this describes your level and type of anxiety, treatment should be sought as there are many options available to you.
OCD is the experience of unwanted thoughts that can cause people to feel compelled to behave in particular ways, so as to relieve the anxiety caused by the thoughts. The condition can be debilitating, and may consist of obsessions such as whether a door is locked, and then checking to see whether the door is locked many times over.
PTSD usually stems from experiences of traumatic events. It affects around a third of those who have endured a life-threatening situation, such as a violent attack or a serious illness, and can present in vivid flashbacks, where the experience is ‘re-lived’ over and over.
Panic disorders refers to experiences of panic attacks, which can last anywhere between two and 20 minutes. Symptoms include profuse sweating, nausea, palpitations, hyperventilation and a sense of dread. Panic attacks can be frightening for people who experience them, but they are not life-threatening.
Social anxiety is the fear of social events and is a common experience. It typically develops in someone’s teenage years, and it can have a significant impact on peoples’ lives. It can improve with age, but some people may require treatment to help ease symptoms, which may include worry about meeting strangers, talking to someone on the phone, concern about appearing incompetent and worry about group activities.
There are many treatments available to you if you suffer from one or many of the above conditions, so even if one treatment has not been effective, there’s likely to be an alternative that works for you. Talking therapies are often used alongside medication, and these combination therapies can be very effective in tackling anxiety disorders.
Vensir works by stopping the body reintegrating serotonin and norepinephrine, which are naturally occurring, feel-good hormones in the body. This increases their levels in the brain, with serotonin improving mood and norepinephrine improving motivation and social confidence.

All drugs come with the risk of some side effects, whether they be over the counter, herbal supplements or prescription. Side effects are hard to predict as everyone reacts differently to every substance they ingest, but it is important to understand the risks involved, no matter how small they are, in order to make an informed choice on the treatment offered to you.

Vensir sometimes causes unwanted effects that you may not be aware of, such as increases in blood pressure or abnormal heart beat, slight changes in blood levels or liver enzymes, sodium or cholesterol. More rarely, Vensir may impair the function of platelets in your blood, resulting in a greater risk of bruising or bleeding. Therefore, your doctor may wish to do blood tests occasionally, especially if you have been taking Vensir for an extended period.

Vensir may also result in a sense of restlessness or an inability to sit or stand still in the initial few weeks of treatment. You should consult your prescribing clinician if you experience these effects.

Vensir may interact with substances present in other medications, so it is imperative that you inform your doctor of any treatment you are currently undergoing, or have undergone in the previous few weeks.
