Common questions about Nastifran (FAQ)
Q: Is Nastifran a long-term medication or is it only for short-term use?
Regulatory documents limit the duration of use for Nastifran due to the risk of the serious neurological disorder called tardive dyskinesia. For chronic conditions, some official guidelines place a maximum limit of 12 weeks of continuous use. In contrast, for acute or short-term issues like preventing chemotherapy-induced sickness, regulatory bodies often recommend use for no more than five consecutive days.
Q: How quickly can a person expect to notice any effects from Nastifran?
The time it takes to notice the effects depends on the form of the medicine used.
