Below is information you may want to consider if you have insurance and receive fosfomycin.

If you have insurance, your insurance company may require prior authorization before it covers fosfomycin. This means the company and your doctor will discuss fosfomycin in regard to your treatment. The insurance company will then determine whether the medication is covered. If a drug requires prior authorization but you start treatment without the prior approval, you could pay the full cost of the medication. You can ask your insurance company whether fosfomycin requires prior authorization.

Now that you’ve learned about cost and fosfomycin, you may still have some questions. Talk with your doctor or pharmacist, who can provide personalized guidance about cost issues related to fosfomycin.
