Patients with epilepsy or other seizure disorders or a history of such should exercise caution while taking this medication since the risk of seizures may increase. This medication cannot replace corticosteroid drugs used for asthma treatment, so patients on steroid therapy should not substitute this medication for their current treatment. Women who are breastfeeding should preferably avoid taking this medication; if unavoidable, breastfeeding should be discontinued. Patients taking oral hypoglycemic agents should monitor their blood count, as this medication may reduce platelet counts. Patients with genetic issues such as fructose intolerance should avoid syrup formulations of this medication due to its maltitol content. Patients already taking other medications for asthma should not abruptly discontinue those medications upon starting this treatment but should taper off gradually. Initial side effects may include drowsiness, dry mouth, and dizziness, but these typically resolve over time. Particularly in children, central nervous system symptoms such as excitability, irritability, and insomnia may occur, necessitating careful observation. Caution is required when operating machinery or driving, as response times may be slower. Patients undergoing steroid treatment should reduce their steroid dosage gradually and cautiously while taking this medication. If an infection is present, appropriate antimicrobial treatment should accompany this therapy, as this medication is not intended to treat seizures or symptoms that have already occurred. For seasonal allergy patients, it is advisable to start this medication before symptoms begin and continue until the end of symptoms. When discontinuing this medication, it should be tapered off gradually over 2 to 4 weeks to reduce side effects. This medication may enhance the effects of sedatives, sleep aids, antihistamines, and alcohol, so dosage adjustments and caution are necessary. The safety of this medication during pregnancy is not well established; therefore, if medication is necessary, it should be used only after consulting a physician and confirming that the benefits outweigh the risks. Although no special dosage adjustments are typically necessary for children or the elderly, careful monitoring is advised for those with impaired physical function.
