Depending on the duration and severity of depression, the psychiatrist, if necessary, apart from psychotherapy, may prescribe antidepressants. These are chemicals that act in the brain as messengers and aim at restoring the chemical equilibrium between neurobiological brain nerve cells. All legally prescribed agents can be effective. But they do not work in an exactly same manner on every man because the neurobiologikal mechanisms of human beings differ from each other. Sometimes you may need to test several types of medication or combinations to find relief from depressive symptoms. Antidepressant medications need 2-4 weeks to implement their antidepressant action.
SSRIs
The SSRIs or serotonin reuptake inhibitors, increase levels of a substance, called serotonin, in the brain that improves mood. Well-known SSRIs is paroxetine (seroxat) fluvoxamine (Dumirox), citalopram (seropram), s-citalopram (cipralex, entact), sertraline (Zoloft). The SSRIs apart from depressive disorders can help in anxiety disorders as well, such as obsessive-compulsive disorder, social phobia, panic disorder, generalized anxiety disorder. These drugs generally have few side effects; most of them resolving with time when continuously administered. If however you are concerned about any adverse reactions do not hesitate to contact your doctor.
Common side effects of SSRIs are:
- Headache
- Tremor
- Anxiety
- Trouble concentrating
- Nausea
- Diarrhea
- Dry mouth
- Change in body weight
- Weakness
- Sweating
- Problems sleeping
- Sexual dysfunction
SNRIs
The SNRIs or serotonin and noradrenaline reuptake inhibitors work in a similar way to the SSRIs except that they increase not only serotonin’s but noradrenaline’s brain levels; the later knowon for its antidepressant effect. Known SNRIs are venlafaxine (Efexor), Duloxetine (Cymbalta, Xeristar). These medicines are also newer and considered to impact effectively both on depressive and anxiety disorders.
Common side effects of SNRIs are:
- Headache
- Anxiety
- Nausea
- Constipation
- Problems sleeping
- Increase of blood pressure
- Sexual dysfunction
They most commonly are transient and abate.
TRICYCLIC
Tricyclic antidepressant drugs category is older but they are more likely in relation to the SSRIs and SNRIs to cause side effects such as sedation, dry mouth and constipation. Tricyclic medications target the neurotransmitters serotonin and noradrenaline, but not as selectivelly as the newer drugs. Some tricyclics are amitriptyline (Saroten), Doxepin (Sinequan), nefazodone (Nefirel), chlorimipramine (Anafranil).
These side effects may be:
- Dizziness
- Dry mouth
- Sedation
- Blurry vision
- Constipation
- Trembling limbs
- Sweating
- Headache
- Tachycardia
- Hypotension
- Weight gain
- Sexual dysfunction
MAOIs
Because monoaminooxidase inhibitors, MAOIs, can have life-threatening interactions with other drugs or with specific foods, they are rarely prescribed in patients. Their prescription tend to limit to cases where reatment of depression with other categories of antidepressants has failed. Moclobemide is characteristically referred as a typical MAO.
CAUTIONIf you are on MAO let your doctor know, especially should he prescribe to you another medication for any other condition. Also ask your doctor to advise you about the foods that you should avoid (rich in tyramine such as various types of cheese, pickles, chocolate, wine, avocados etc.)
CAUTION
- If you are on other antidepressants as well as formulations with anxiolytic action such as St. John wort, Ecstasy or other analgesics, let your doctor knw. There is a risk of dangerous interactions.
- Patients who are being treated with antidepressants should be constantly checked for possible paradoxical increase of suicidal thoughts and behaviors, especially when changing to another medication or dose.
