Read on to learn about metronidazole and cost, as well as how to save money on prescriptions.
As with all medications, the cost of metronidazole can vary. Factors that may affect the price you’ll pay include your treatment plan, your insurance coverage, and the pharmacy you use. Your cost will also depend on whether you receive metronidazole injections at a clinic or hospital.
To find out what the cost of metronidazole will be for you, talk with your doctor, pharmacist, or insurance provider.
Below is information you may want to consider if you have insurance and use metronidazole.
Prior authorization. If you have insurance, your insurance company may require prior authorization before it covers metronidazole. This means the company and your doctor will discuss metronidazole in regard to your treatment. The insurance company will then determine whether the medication is covered.
If a drug requires prior authorization and you start treatment without the prior approval, you could pay the full cost of the medication. You can ask your insurance company whether metronidazole requires prior authorization.
Type of insurance coverage. Metronidazole injection is given by a healthcare professional at a hospital or clinic. (You can take or use the other forms of metronidazole at home.)
If you have insurance, the price of metronidazole injections may be billed through your primary health insurance instead of the prescription drug portion of your insurance. This depends on your insurance coverage and where you receive your metronidazole injection doses, such as at an infusion clinic or hospital.
If you have questions about this process, contact your doctor or insurance provider.

To find out more about the cost of metronidazole gel and cream, ask your doctor or pharmacist for more information. They can discuss your treatment plan and tell you how the gel and cream versions compare. Depending on the price difference, you can let your doctor know whether you have a preference for the gel or cream.
How can I determine metronidazole’s cost without insurance?
Metronidazole’s cost without insurance depends on the form of the drug your doctor has prescribed, your treatment plan, and even the pharmacy you use. The cost of the oral forms of metronidazole may be different from the topical forms.
The cost of metronidazole IV injections will typically be higher than oral or topical forms of the drug. This is because there may be a separate cost to receive the drug from a healthcare professional at a hospital or clinic.
Note that the form of metronidazole your doctor prescribes will depend on the condition being treated. As a result, you may not be able to switch from one form to another.
To find out the costs of different forms of metronidazole, talk with your doctor or pharmacist.
