Losec & Constipation?

Does anyone know if a side effect of Losec is constipation? DS seems to be having a lot of trouble going to the toilet (and has done for weeks now) and has now developed an anal fissure. The doctor suggested Coloxyl drops which seem to work for a day or so and then the problem starts all over again. I also dont feel comfortable using a laxative constantly on him. I dont think it is his milk intake, as he is breastfed and supplement feed with NAN HA gold, previously having been on Karicare. I thought i may start giving him a small amount of prune juice each day, but not sure if this is 'allowed'.

"Gold" formulas have been known to cause constipation, this may very well be your little one's problem.
