Baden-Clay said they went to New York, then back to England where Ms Baden-Clay “crashed”.
“We took her to (a) hospital… and that was the first time we became aware of the possibility of the Lariam being a trigger for the episodes Allison had been having,” he said.
The accused said a doctor told them the drug should work its way out of their system when they stopped taking it.
He said they returned to the scout camp in Switzerland in voluntary roles as part of a nine-month contract.
“We were paid pocket money, we always had food and accommodation supplied… it was enough to be able to go into the village for a nice dinner once a month or something like that or buy some Toblerones occasionally,” he said.
Baden-Clay said his wife appeared to get better but there was an unprecedented snow fall in the Alps and the slopes in the valley where they lived was prone to avalanches, resulting in evacuations throughout their village.
“Allison did not respond well to that whole situation at all,” he said.
“There were times when she thought in her paranoia that the sky was falling in, so when it became a physical possibility that would happen… she was very, very, anxious.
“I covered her by saying she was not well, had a cold or a headache or that sort of thing but it was because of that.”
He said they stayed in the village until September.
