Duloxetine is an anti-depressant. Anti-depressants are drugs that lift mood and, therefore, are used to prevent or reduce depression.
In South Africa duloxetine is registered for the treatment of depression, a mental state characterised by a pessimistic sense of inadequacy and a despondent lack of activity.
It can be used as a treatment on its own, or in combination with other medications used to treat depression.
For this medication to be effective it has to be taken regularly, even if you do not notice an immediate effect. Treatment should not be stopped abruptly, especially if you have been taking this drug for a prolonged period of time. To prevent withdrawal and a return of symptoms you should decrease your dose gradually only as directed by your doctor.
This medication does not cure the underlying condition, but simply keeps the symptoms under control.
It should be noted that because this drug may cause dizziness, light-headedness and/or sedation, driving and any hazardous tasks should be avoided until you know how this medication affects you.
How does duloxetine work? Duloxetine acts on two chemical messengers in the brain, serotonin and noradrenaline, which, amongst others, act to lighten mood. Depression is thought to occur when those of us prone to depression, can’t sufficiently replenish levels of these chemicals after they are reabsorbed into the nerve cells. Duloxetine works by preventing the reabsorption of these chemicals, thereby keeping levels of serotonin and noradrenaline at a sufficient level to avoid depression.
