After the diagnosis of Parkinson’s disease is clear, treatment should be started because Parkinson’s disease is a chronic progressive neurodegenerative disease, and there is no single drug or measure that can cure Parkinson’s disease at the current international level. Doctors often start with small doses in order to determine whether the patient can adapt to anti-Parkinson’s drugs. If the patient can adapt and there are no significant adverse reactions, the doctor will gradually increase the dose of the drug until it reaches a suitable dose that will be more effective. Therefore, when the effect of early medication is not obvious, patients should not lose confidence in the drug because of this. Some patients who read the instructions will have adverse reactions, often do it on their own and stop the drug themselves, and as a result, they do not achieve the desired effect. Anti-Parkinson’s disease drugs do have some adverse reactions, but these reactions can be overcome as long as the doctor is informed in a timely manner, and the doctor can adjust the dose of the drug, the number of doses, or the simultaneous use of other drugs, so that most of the adverse reactions can be overcome. Some patients thought that the more they took the drug, the better the effect, so they took the initiative to increase the dose of the drug, which led to various adverse reactions, such as dry mouth, dizziness, constipation, low blood pressure, uncontrollable dance-like movements. After taking the drug for a period of time, some patients find that the efficacy of the drug is diminishing, and they think that their bodies have developed drug resistance. In fact, this is not the case. The cause of this phenomenon is often the result of the progressive disease. The rate at which this happens varies from person to person, and the doctor will adjust the medication according to the patient’s condition. There are differences in the sensitivity and tolerance of each patient to the drug, and timely feedback should be given to the doctor on the time of onset of effect, the time of maintenance of the effect, and the adverse reactions after taking the drug, so that the medication regimen can be adjusted.
