Parkinson's and Treatment

What is the treatment for Parkinson’s?
Unfortunately there is no cure for Parkinson’s at this stage but there are many different treatment options available which can help reduce the symptoms of Parkinson’s and improve quality of life of patients significantly. Drug therapy is the mainstay of treatment of Parkinson’s. Physiotherapy and speech therapy are also helpful in conjunction with medications. Carefully selected patients may benefit from surgery as well.

Which treatment do I need?
The treatment of Parkinson’s may vary person to person and depends on a number of factors such as symptoms at the onset, the side of body involved (dominant versus non-dominant) and age at onset. A working person may need to be started on drug therapy earlier than someone who is retired because of difficulty in carrying out activities related to employment. The medications are usually started before or when your activities of daily life are starting to be affected because of Parkinson’s.It is important to keep in mind that these drugs will not stop the progression of the disease. However, they will reduce your symptoms, so you are better able to carry out your daily activities. The medications used for Parkinson’s may have some potential side effects as well. The medications must only be used as prescribed by physician. Do not adjust the dosage of your medications without the advice of your physician.

What are some steps I can take to manage my drug treatment?

  • The medications should be taken at the fixed time and in right dosage as instructed by your physician.
  •  Discuss the efficacy and side effects with your physician at regular follow up visits. 
  • You should use the same pharmacy consistently, so they have a record of your medication history. Thus, there is less of a chance you will buy a prescription free product that may interfere with your drug treatment.
  • Always try to drink a glass of water with each dose of your medication. This will help the absorption process of the medication.
  • You should swallow the controlled-release tablets without chewing them. Thus, the contents will be able to reach their target destination more efficiently.
