Biston review





Biston, also known as CBZ, is an anticonvulsant medication and a mood-stabilizing agent. It acts by decreasing the amount of abnormal excitement in the brain and is used for epilepsy and the treatment of bipolar disorders.

Biston is effective in controlling seizures by blocking certain brain impulses. It is also used for ADD (Attention Deficit Disorder), ADHD (Attention Deficit Hyperactive Disorder), and schizophrenia (a psychiatric condition).

Used by itself or combined with other seizure medications, Biston is used to calm manic episodes where the patient exhibits extreme mood swings, mixed episodes of mania and depression, and other abnormal moods.

Biston can also be used for the treatment of trigeminal neuralgia, a condition that causes severe pain in the facial nerves. Biston shifts nerve impulses from the affected facial nerves to ease the pain that accompanies this condition.

Biston is also prescribed for mental illnesses like depression, post-traumatic stress disorder, withdrawal from medication and alcoholisms, restless legs syndrome, diabetes insipidus and a children's disease called chorea.

Patients with a history of bone marrow suppression, porphyria (a blood disorder) and atrioventricular block (a severe heart block problem) should not take Biston as the medication will only make their conditions worse. Patients taking antidepressant medications like amitriptyline (Elavil), desipramine (Norpramin), imipramine (Trofranil), or nortriptyline (Pamelor) should refrain from taking Biston to prevent adverse interactions between the medications.

Other medications with negative interactions include cold and allergy medicines, pain relievers, sleeping pills, muscle relaxants, antidepressants like isocarboxazid (Marplan) and phenelzine (Nardil), and anti-anxiety medicines like tranylcypromine (Parnate). Patients who are taking selegiline, a medication to treat early-stage Parkinson's disease and senile dementia, should refrain from taking Biston.

Patients are advised not to drink alcoholic beverages while taking this medication to avoid the risk of seizures. They should inform their doctor if they are currently taking any prescription or over-the-counter medications, including vitamin, mineral or herbal supplements before starting Biston treatment.

Biston has been classified in pregnancy category D by the Food and Drug Administration. Consequently, use of this medication can harm an unborn baby. As it can be passed on through breast milk and harm nursing infants, patients should refrain from breastfeeding while taking Biston. Biston can decrease the effectiveness of birth control pills. Patients will need to tell their doctor of the contraceptive measures they are using before beginning medication. Biston also has the effect of lowering the body's infection-fighting blood cells. Patients on this medication need to have their blood and liver functions checked regularly.

Other side effects include drowsiness, dizziness or headaches, vomiting, anxiety, constipation or diarrhea, pyrosis, dry mouth, back pain, and impaired motor coordination or unsteadiness of movement. In some rare instances, Biston can also cause cardiac arrhythmias, blurred eyesight or double vision, and some loss of blood cells or platelets.

Severe side effects like allergic rashes, breathing difficulties, confusion, depression, suicidal thoughts, chest pain, black or tarry stools, jaundice, and losing touch with reality are very rare, but these are considered serious and need immediate medical attention.

Biston is sold under many brand names, and these include Tegretol, Calepsin, Carbatrol, Epitol, Equetro, Finlepsin, Sirtal, Stazepine, Talesmin, Teril, Timonil, Trimonil, and Epimaz. The medication comes in tablet form, chewables, extended-release tablets and capsules, and a liquid (suspension).
