Brief Answer:
Unlikely this dose will create problem.
Detailed Answer:
Dear Friend.
Thanks for sharing with us.
Meftal Spas , if taken once or twice a month , for dysmenorrhea (excessive pain in
menstruation) , it is not a problem.
Kidney problems due to NSAIDs (pain killer) use is called as NSAIDs induced Nephropathy and it occur due to :
1. Chronic Long term abuse.
2. High dose consumption.
So , once or twice a month consumption should not be a problem to your kidneys.
But the problem , that can occur with even this much dose is ,
Gastritis (Acidity) problem.
So , i always prefer to give my patients drugs like
Pantoprazole once a day with these pain killers.
You don't need to find a substitute , because for dysmenorrhea , this is the best drug.
With the course of time , dysmenorrhea also subsides it self , so you would not require it.
However , for the other problems you are describing i would suggest you to get your
Hemoglobin checked , especially if you also have heavy bleeding during your periods.
If the itching you had after consuming Meftal Spas is for the first time , it could be an
allergic reaction , if you are taking this for long , and itching is for the first time , it is unlikely to be due to Meftal Spas.
I hope i am able to solve your query , still if you have any query , you may ask me.
