After a sickness bug this weekend my daughter has become constipated from lack of fluids, even though we tried our best to keep her hydrated. She’s been wanting to poo now since yesterday lunch time but can’t. It’s painful and she gets really distressed. I rang the doctors yesterday afternoon but couldn’t get a call back. A relative went to the local chemist & the pharmacist said we could give her lactulose. No instructions were given on how my daughter should take it. Read the leaflet and all it says is 5ml-10ml daily for her age. She had 2.5ml at 5pm yesterday and another 2.5ml at 10pm after waking up screaming her bum hurt. I have gave her 3 lots of 2.5ml so far throughout the day and was planing on giving her one more before bed so she’s had 10ml. As she’s still not poo’d and she’s still struggling, upset & distressed I looked on NHS website. That says she should take 5ml twice a day. That’s not what I’ve been doing I’ve been giving her 2.5ml 4 time’s a day. Will it still work ok? Shall I change to 2 lots of 5ml tomorrow? Also in the leaflet it says I shouldn’t give it to her without speaking to a doctor first but the pharmacist knew the situation and let us buy over the counter. Should I ring the doctors to discuss tomorrow? Daughter has never suffered from constipation before so I have no idea what to do
