Risperdal and Invega are both atypical anti-psychotic drugs existing for years now and among the bestsellers in the market. Both drugs made billions of dollars for its creator, which concludes that, countless number of people have already consumed these drugs. That being said simply means that there are people out there who are suffering from Risperdal’s horrible serious adverse effects which could be permanent movement disorders.

Both Risperdal and Invega are newer version of antipsychotic drugs to which the formulation is different from the older version. They perform with greater efficacy to treatment-resistant patients but despite of this, these Second-Generation Antipsychotics have their own downfall as they could lead to movement disorders such as Parkinsonism, dyskinesia and tardive dystonia.

They feel embarrassed to go out to the public as the drug-induced condition could happen at any time, in any day. The problem may still continue even after they stopped the medication that caused the condition.
