I can't speak for them but having been in similar situations in a long term relationship I'm sure they didn't mean a few days literally. Especially knowing it's due to an issue with medication, that takes time to sort itself out. A few days in terms of getting back on track could be anywhere from a week to a month or two depending on safety concerns and severity of symptoms. I could be totally wrong too, that's just my unsolicited opinion on the matter haha
