As we age we may become less responsive to drugs or more likely to experience side effects.
Changes in the body’s physiology may reduce the benefits of some drugs but create a potential for benefit in another, even if that drug has been tried before. For example, an individual who could not tolerate a drug at an average dose in their 40s may experience a benefit from the same drug a decade later at a fraction of the dose.
Some individuals—including those with severe dystonia—find that after trying many prescription medications, adequate relief can be achieved through over-the-counter analgesics and non-drug methods such as regular relaxation and gentle exercise.
If you are being prescribed medications by multiple doctors, be sure that each doctor is aware of every drug you are taking. Consider keeping a written list of all current medications (both oral and injected) and bringing that list to every medical appointment.
