Psychiatric drugs
Atypical antipsychotics may increase the effects
> certain classic antipsychotics
> certain antidepressants (tricyclics and SSRIs)
> anxiolytics and hypnotics
> narcotics
> barbiturates
Tegretol decreases the effect of Risperdal
All antipsychotics decrease the effectiveness of antiparkinsonians, such as levodopa
Physical health drugs
May increase the effects
> sedative antihistamines (medicines for allergies)
> antihypertensives (medicines for high blood pressure)
> antiarrhythmics and beta-blockers (heart medications)
Ciprofloxacin (antibiotic) may increase the toxic effects of clozapine and olanzapine (Zyprexa)
Natural products and food
Avoid taking:
> valerian
> ginseng

Side effects

Diarrhea
Difficulty urinating
Frequent need to urinate
Members
Effects less common with second-generation antipsychotics
Tardive dyskinesia (TD). The risk of developing TD and the likelihood of it becoming irreversible increases with duration of treatment and total cumulative amount antipsychotics administered to the person. Older women are most at risk for DT
Tardive dystonia. May be irreversible
Late akathisia. May be irreversible
Akinesia
Parkinsonism
Sexuality
Sexual problems including low libido, ejaculation problem, erection problem
Cessation of menstruation
Priapism (persistent and painful erection appearing without sexual arousal)

Blood
May cause type 2 diabetes, hyperglycemia (more common with Zyprexa)
May raise cholesterol
Sleep
Shortened or lengthened duration of sleep
Insomnia
Drowsiness
Having more dreams or nightmares
Psychological
Dysphoria (mood disturbance characterized by an unpleasant and disturbing feeling of sadness, anxiety, tension, irritability; opposite of euphoria)
Asthenia. Weariness, feeling tired.
Very similar to depressive symptoms to varying degrees in many people taking antipsychotics
Difficulty concentrating
Memory problems
Psychosis
Monitoring and medical supervision
Actions one can take to avoid iatrogenic effects (which are caused by medicine)
All persons receiving atypical antipsychotics should be monitored for symptoms of diabetes, hyperglycemia, such as frequent urges to drink, urinate, eat, and feeling weak. Fasting blood glucose testing is recommended before and during treatment. Closer follow-up for people who combine several risk factors.
Weight gain must be assessed and managed. Professional monitoring of nutrition and exercise is recommended.
Evaluation before and during treatment of cholesterol and triglyceride levels.
Individuals should be assessed at least once a year and preferably by a neurologist for dyskinesia, dystonia and akathisia.
The liver, kidneys, heart, lungs and eyes should be evaluated before and at regular intervals during treatment.
Withdrawal symptoms
Psychotropic drugs act in the brain just as they do in the rest of the body; and as we have seen, each person reacts differently. It's the same with weaning; the person's metabolism, the type of drug, the dose as well as the duration of the intake and its half-life, explain that the withdrawal effects are varied. We have listed the potential and main withdrawal symptoms of each class of psychotropic drugs. This list is incomplete, as not all withdrawal effects are listed; moreover, knowledge is rapidly evolving in this field. A person may have no withdrawal symptoms or experience one, a few, or even many. The medication reduction journey is specific to each person, just as each process is unique. For example, a person can take the same medicine twice at the same dose and the effects will be different. Gradual reduction, like removing 10 % of dose per week/month, reduces the frequency or intensity of withdrawal symptoms and the incidence of rapid relapses. It is very important to undertake this process with the collaboration of your doctor. The pharmacist also plays a key role and can provide guidance to monitor withdrawal effects for each medication. Most people who will have withdrawal symptoms will tolerate them without problems for the short duration of these symptoms.
Common and frequent withdrawal symptoms for all classes: anxiety, nervousness, restlessness, sleep problems, greater need to rest, sleep, irritability, fatigue.
Withdrawal symptoms for neuroleptics :
Withdrawal symptoms appear a few days after the dose is reduced. In the process of progressive reduction according to the method of 10 %, the last step can be particularly difficult. It can be lengthened or split to reduce withdrawal symptoms.
Main psychological withdrawal symptoms:
Withdrawal psychosis
Nervousness or restlessness
Insomnia
Main physical withdrawal symptoms:
Muscle stiffness; body aches (sore all over)
Tremors
Sweat
Runny nose
Nausea, vomiting
Cramps, abdominal pain
Diarrhea
Salivation
Headaches (headaches)
Nightmares
Palpitations
Hypertension
Discovery of tardive dyskinesia (Definition: abnormal and involuntary movements of the tongue, jaw, trunk or extremities whose appearance is related to the taking of neuroleptic drugs. tardive dyskinesia may become irreversible.)
Clozaril carries a higher risk in relation to withdrawal psychosis because its duration of action is short.
