Allergy

Being in advanced age I need to take fibre for abdomen health/ age related constipation. The problem is that very few fibres suite me. I get mouth ulcers if I take Ispaghol continuously for 2 days or so. Recently, I tried taking Fybogel (which is mainly Ispaghol) during evening meals and I found that it does not create ulcers. Hence I keep taking one sachet of Fybogel with evening meals.

However Fybogel as described above does not suffice alone  for me. Hence, I have to supplement it with another Fibre. Thus I  tried Senokot 1 tablet a day which worked very well but as its side effect I got red coloured patches all over the body which vanish after a short while with anti allergic medicine or even without medication.

Due to good action of Senokot on my abdomen, I like to continue Senokot but am apprehensive its adverse effect on the skin. I like to ask if any one else had such an adverse effect of Senokot or any other fibre containing Sena element? [/b]I did try some other fibres (having some Sena) which also created problem for me.
