A common neurological condition known as epilepsy is characterized by recurrent bouts of uncontrollable body movements that affect only a portion of the body (partial) or the full body (generalized), occasionally accompanied by loss of consciousness and control over bowel or bladder function [12]. The most prevalent neurological condition, epilepsy, is characterized by recurring seizures brought on by abnormally high levels of synchronized neuronal activity in the brain [13]. Epileptic seizures typically result in a temporary disturbance of awareness that puts the person at risk for physical harm and typically interferes with learning and working [14].
The symptoms that are associated with epilepsy include: autonomic symptoms like sweating, flushing, and dilated pupils; motor symptoms like tingling, numbness, lip-smacking, convulsive jerking incoordination, dystonic, chewing motions; sensory symptoms like paresthesia; aura; auditory, gustatory, olfactory, visual, and vestibular disturbances; hallucinations, dysphasia of behavior impairments in cognitive functioning, memory, and responsiveness [15].
Recurrent seizures are the first audible sign of epilepsy and are caused by ion channel dysfunction on synapses during neurotransmission [16]. Most epileptic syndromes share a common trait: a sustained rise in neuronal excitation or hyperactivity [17]. Brain injury and chemical imbalances are the two main causes of the abnormal behavior of neurons. Low blood levels of salt, calcium, sugar, and oxygen are examples of chemical imbalance [18]. Intracranial hemorrhage, brain oxygen deprivation, infection, trauma, tumor meningitis, stroke, and other neurological diseases are all examples of brain injuries [19].
Medicine non-adherence is the failure to properly fill or refill a prescription, stop taking a medication before the course of therapy is complete, follow the agreed-upon advice of a healthcare professional, take more or less of a medication than recommended, or take a dose at the wrong time [20]. All anticonvulsants have side effects, some of which may be very significant since they jump into the fantastic of life, start non-compliance, and, in rare instances, be implausibly life-threatening [21].
The ultimate goal of epilepsy treatment is to prevent seizures, eliminate side effects, and maintain a high quality of life. As a result, treatment plans should be tailored to each patient's unique needs to prevent or lessen seizures while avoiding drug interactions and side effects, preventing other complications, and achieving the highest level of quality of life feasible [22, 23]. Behavior issues, hyperactivity, sedation as a main adverse effect, dementia, loss of appetite, fatigue, vertigo, and sleepiness are all potential side effects of phenobarbital [24]. The side effects of phenytoin may include sedation, psychosis, hyperkinesias, megaloblastic anemia, decreased serum folate levels, gingival hyperplasia (overgrowth of the gums), decreased bone mineral content, liver disease, acne, hirsutism (excessive hair on the face or body/overgrowth of hair), coarseness of facial features, unsteadiness or shakiness, and ataxia [2].
Phenytoin can also cause hyperandrogenic symptoms such as hirsutism and nodular skin lesions, diplopia (cerebrovascular malfunction), exfoliative dermatitis, toxic epidermal necrosis, and lupus-like syndrome by altering the metabolism of sex steroid hormones [2]. In this study, the least frequent reason for non-adherence was complicated treatment plans, while anti-epileptic drug side effects were the most frequent.
