Licensed provider oversight ensures FDA-approved antiparasitic treatment is safe, correctly dosed, and monitored for you.
Medical supervision is required because prescription antiparasitic medications like ivermectin and mebendazole are only safe and effective when matched to the right person, condition, and dose. A licensed provider reviews your health history, checks for contraindications, and decides whether treatment is appropriate — dosing and suitability are never something you determine on your own.
## Why a Prescriber Has to Be Involved
FDA-approved medications carry specific, tested dosing instructions tied to particular infections. Using them safely depends on confirming the diagnosis fits an FDA-approved use, checking your liver and kidney function where relevant, and screening for other medications that might interact. This is exactly the kind of judgment call a licensed clinician is trained to make, and it's why platforms like [Get It Prescribed](/how-it-works) build a provider review into every order rather than shipping medication on request.
## What Provider Review Actually Involves
- Verifying your reported symptoms and history are consistent with an FDA-approved indication - Confirming no allergy or prior adverse reaction to the medication class - Checking current prescriptions, over-the-counter drugs, and supplements for interactions - Considering pregnancy, breastfeeding, or major organ disease as factors that change the risk-benefit picture - Setting an appropriate dose and course length based on your specific situation
## Baseline and Follow-Up Checks
For some patients, a provider will want baseline information such as liver function or a general health review before prescribing, particularly if there is pre-existing liver or kidney disease or if other medications are involved. Follow-up isn't always required for a short antiparasitic course, but your provider will tell you if it is, and you should always report new or worsening symptoms.
## How This Works on Get It Prescribed
| Step | What happens | |---|---| | Intake | You complete a health questionnaire describing your symptoms and history | | Provider review | A licensed clinician evaluates whether an FDA-approved medication is appropriate | | Prescription | If appropriate, a prescription is sent to a pharmacy in your name | | Follow-up | You can message your provider with questions or new symptoms |
You can read more about this process on our [eligibility and provider review](/eligibility-and-provider-review) page, and see the medications themselves on the [ivermectin](/medications/ivermectin) and [mebendazole](/medications/mebendazole) pages.
## Why You Shouldn't Source These Medications Elsewhere
Obtaining prescription antiparasitics without a clinician's evaluation removes every one of the safety checks above. Formulations not intended for human use, incorrect dosing, and undetected drug interactions are all real risks. The FDA and pharmacist community consistently recommend against using veterinary formulations in people or dosing prescription medication without professional guidance.
## When to Contact Your Provider After Treatment
Contact your prescribing provider if you develop a rash, persistent nausea, yellowing of the skin or eyes, dark urine, or any symptom that concerns you after starting treatment. Prompt reporting lets your provider decide quickly whether the medication needs to be stopped or adjusted.
## Related questions
### Can I get an antiparasitic medication without seeing a provider? No. FDA-approved antiparasitic medications are prescription-only, meaning a licensed provider must evaluate you first. This protects you from an incorrect diagnosis, an unsafe dose, or a missed drug interaction, and it's a legal requirement in the United States regardless of where you order from.
### How quickly can I be evaluated by a provider? Online provider review through services like [Get It Prescribed](/how-it-works) is often completed within a day of submitting your intake questionnaire, though timing depends on your answers and whether the provider needs more information from you.
### Will my provider always prescribe the medication I request? Not necessarily. Your provider prescribes only when your history and symptoms support an FDA-approved use and there are no contraindications. If a medication isn't appropriate, they will explain why and discuss other options.
### Do I need lab work before starting an antiparasitic medication? Not always. Many short courses for common parasitic infections don't require baseline labs, but your provider may request them if you have liver or kidney disease, take interacting medications, or have other risk factors.
