My dog has flea allergies. Can I use Simparica and Advantix?

Pet's info: Dog | Labrador Retriever | Male | neutered | 2 years old | 77 lbs

Hi, my dog has just been subscribed Simparica. I see this only kills adult fleas once he has been bitten by them, is therefore possible to also use Advantix in his coat as that kills all life stages of the flea. My dog does suffer from flea allergies so I thought this might be useful to attack his problem from all angles so to speak.

They are each labeled for once a month so it is safe and will be more effective if you alternate them every 2 weeks instead of using them at the same time each month. make sure the environment stays treated also to minimize what gets on him.
