Why the effect of sastravi is warning out just 1 hour after taking the drug?

My husband was diagnosed with PD 11 years ago. In the last few days after years of effective treatment (stalivi and then sastravi ) the drug stops working 45 min after being taken. It is shocking contact - from being able to do most every day activities to unable to even roll him self in the bed. Why is this happening? And why so suddenly? Any suggestions please.

Hi Lenamog,

This sudden change must be very upsetting for you both. We would suggest your husband get medical advice from his doctor as soon as possible. Our helpline specialists can also advise you about medical issues and symptoms. Please feel free to give them a call on 0808 800 0303 for support and advise.

Best wishes,
