Factual error: The medication Monk is given is called Doxinyl, which is a real medication, but it's an antihistamine, used to relieve allergy symptoms, nothing to do with OCD and certainly wouldn't cause the side effects shown.
Answer: Through the entire show, I don't recall her ever mentioning another job. The two explanations I had for being able to afford those cars, was there might have been a life insurance policy after her husbands death (or Mitch left her quite a bit after he died). The other may have been she had accepted some money from her family willingly or unwillingly asked for it. But in truth, I would imagine it was for product placement in the show. Most shows like Monk tend to keep the characters moderately wealthy or financially healthy, so they can insert products or items for the characters to use. Phones, food items, cars etc.
