My old grandmother is very ill and bed-ridden since last month. She is 84 years old. Lately she has been having constipation problems and my mother wants to buy something called Codalax for this problem. Her friend has told her about this medicine. It is not available in any pharmacies in our locality hence she's ordered it from an online pharmacy Buy CODALAX Online Now (http://www.drugdelivery.ca/s31020-s-CODALAX.aspx). But I am worried since we have never bought anything from this pharmacy before. Anyone knows this pharmacy. Is it legit? Also anyone used this product? Is it good for old people?

Before you start any medication - over the counter or otherwise - check with your grandmother's doctor.
To help with this - you could also change her diet around. Drinking more water, adding foods that help with constipation.
Good Luck.

I am going to have to strongly agree with NW on this.

You should never give any new medication to the elderly (which your grandmother is) without notifying her physician. You see, our elderly population can be very sensitive to medications, and you are adding a new one that she is not used to, without doctor's supervision. She is most likely on several meds as it is, and you do not know whether this will cause any potentially dangerous interactions with the meds she is already taking.

If she is suffering from constipation it is imperative that she see her doctor to find the cause and rule out any underlying condition.
