Welcome to HCM and thanks for posting your query here.
Alfusin and potrate are used for urinary tract infection
. If the infection is subsided then no need to use Niftran
. Niftran is an antibiotic which is used particularly to treat Urine infections.
To confirm whether the infection is cured or not you can go for a routine urine check.
If the issue persists then you can start with Niftran.
To avoid urine infections further in the future maintain your water balance. Daily take atleast 4 to 5 litres of water. If you cannot take water purely as such you can take it in the form of fruit juices, soups, butter milk, coconut water(if not diabetic) etc.
All the best.
