Are Diarrhea And Vomiting Symptoms Of Celiac Disease?
Possible side effects of Lamotrigine.
Detailed Answer:
Hello and thanks for using HCM.
I have read your question and understand your concerns.
I don't think it is coeliac disease that is causing your son's vomiting and diarrhea, those symptoms are probably side effects of Lamotrigine use.
Vomiting can be related to increased intracranial pressure from different conditions and MRI will give valuable information about this possibility.
Coeliac disease is a condition related to gluten intolerance and avoiding gluten containing food is the best treatment.
So, your son can use gluten free food, if you suspect coeliac disease is causing vomiting, stomach upset and diarrhea.
Muscles and joints pain, stiffness are all symptoms of nocturnal seizures.
Correct control of seizures should prevent these symptoms too.
Keppra is a good possibility to control nocturnal seizures, other possible drugs to use in such cases are Oxcarbazepine, Phenytoin, Valproate etc.
Valproate helps in weight gain too.
To conclude, in my opinion, Lamotrigine should be substituted with another antiseizure drug, ( valproate for example ) and a benzodiazepine ( clonazepam 3x0.5 mg for one week ) should be used too, until long term antiseizure drug starts to have the maximal effects.
Hope you found the answer helpful.
Let me know if I can assist you further.
Greetings.
