Why get your antiparasitic prescription through Your Doctors Online?

Skip the walk-in clinic lines, get diagnosed, and receive a prescription online within minutes.

Talk to a board-certified doctor in 5 minutes, day or night

Parasite symptoms rarely show up at a convenient time. Pinworm itching starts at night, scabies worsens after dark, and travel-related infections can hit days or weeks later. Connect with a board-certified doctor anytime, without waiting for a clinic to open.

Privacy that an in-person clinic can't give you

Parasite infections can feel uncomfortable to talk about in person. With Your Doctors Online, your consultation happens securely on a HIPAA-compliant platform, so you can discuss symptoms, get diagnosed, and receive treatment discreetly from anywhere.

Care that understands travel-related infections

Many parasitic infections appear after you return home. Giardia, Strongyloides, and schistosomiasis can show up days to weeks later. Your Doctors Online physicians take a full symptom and travel history to help identify the cause faster and recommend the right treatment.

Choose your local pharmacy

After the consultation, your antiparasitic prescription is sent electronically to the pharmacy of your choice. You walk in, pick it up, and start the dose.

Drug Education

What is antiparasitic medicine?

Antiparasitic medication is a class of prescription drugs that kill or paralyze worms, protozoa, and ectoparasites like lice and scabies, and other parasites, so the body can clear them.

The most prescribed antiparasitic medications for humans are Albendazole, Mebendazole, Praziquantel, and Ivermectin, each targeting a specific parasite type. The right drug depends on the parasite, your age, whether you're pregnant, and any other medications you take.

Antiparasitic medication for travelers

If you travel to regions where parasites are common, you may need antiparasitic medication before, during, or after your trip.

Malaria prevention

Required if visiting malaria-endemic regions (e.g., sub-Saharan Africa, South America, SE Asia). Taken before, during, and after travel depending on destination, medical history, and trip length.

Common Options: Atovaquone-proguanil (Malarone) · Mefloquine

Travelers' diarrhea and Giardia

Persistent diarrhea, bloating, or weight loss following travel may point to a Giardia or amoebiasis infection. Seek medical attention if symptoms persist for a week or more after returning home.

First-line Treatment: Metronidazole · Tinidazole

Strongyloidiasis & Schistosomiasis

Unexplained skin rashes, abdominal pain, or elevated eosinophilia on return from tropical or subtropical regions should trigger screening. Diagnosed via combined stool studies and serology.

Common Causes: Strongyloides · Schistosoma

Ectoparasites (Scabies & Lice)

Crowded accommodations and hosteling increase close-contact risks. Scabies requires full head-to-toe topical cream (or oral Ivermectin). Head lice respond to OTC or prescription lotion treatments.

Treatments: Permethrin (1% or 5%) · Spinosad · Oral Ivermectin

Frequently asked questions

Do I need a stool test before I can get Albendazole or Mebendazole?

No, you don’t always need a stool test before getting an albendazole prescription or mebendazole. In most routine cases, diagnosis is made based on your symptoms. Our online doctor can prescribe treatment if there are clear signs of worms and liver flukes in the stool.

Is it legal to get Albendazole online in the U.S.?

Yes, it is legal to get Albendazole online in the US when obtained through a doctor’s prescription. You can get a valid prescription via Your Doctors Online. We have a team of certified online doctors authorized to prescribe Albendazole online and follow the telehealth regulations set by Department of Health and Human Services.

Is Albendazole safe for toddlers?

Yes, Albendazole is safe for treating parasite infections in toddlers, but it should always be taken under a doctor’s supervision. At our virtual clinic, we prescribe Albendazole to children aged three and above.

What is the best prescription medication for intestinal parasites?

There is no single “best” antiparasitic drug for all parasites. The treatment depends on the type ofinfection, and different parasites require different medicines to be eliminated.

Mebendazole or Albendazole to treat pinworms:
Albendazole, Mebendazole, and Pyrantel pamoate to treat hookworms
Praziquantel to prevent bilharzia

It’s important to follow the doctor’s guidance on which medication is best for your situation.

How long does it take for antiparasitic medication to work?

Antiparasitic medications work quickly, often killing parasites within the first 24–48 hours after a dose is taken. However, the exact time will depend on the type of antiparasite medication you use. For instance, medication for pinworms starts killing pinworms right away, but for hookworms, you might have to wait a week to start seeing the improvement in symptoms.

How often should you take antiparasite medication?

You should take the antiparasite medication as per your doctor’s prescription. If you are advised to take it twice daily, do so until you are completely dewormed.

Can I get rid of a parasite infection without seeing a parasite doctor?

Some parasitic infections may resolve independently, particularly with a robust immune system and a balanced diet. Persistent cases often necessitate oral prescription medication, which is generally effective. You can skip the in-person doctor’s visit using our virtual clinic app. Our family doctors are open 24/7 to diagnose and issue online prescriptions to help you recover sooner.

What antibiotics can treat parasites?

Antibiotics work against bacteria only and do not kill parasites. However, you can be prescribed antibiotic-like medications such as Metronidazole and Tinidazole for Trichomoniasis. These medications are classified as antibiotics but are effective against anaerobic protozoan parasites such as Entamoeba histolytica, Giardia lamblia, and Cyclospora.

Can I buy Mebendazole over the counter?

Mebendazole is a prescription medication, and you cannot get it over the counter. You can get an online prescription for Mebendazole within 5 minutes through Your Doctors Online. All you have to do is:

Create an account
Share your symptoms
Talk to an online parasite doctor
Get a prescription for Mebendazole at your local pharmacy

What if my symptoms do not improve?

If you’ve taken the full course of your antiparasitic medication and you’re still experiencing symptoms, it’s important to follow up with a doctor. Sometimes a single round of treatment doesn’t completely clear an infection. For example, heavy infestations might need a second round, or in the case of pinworms, reinfection from eggs in the environment can occur if the hygiene measures weren’t strict. In such cases, our online parasite doctors will assess your situation again and may prescribe a refill of the antiparasitic drug if appropriate.

What is the dosing for antiparasite agents prescribed online?

Although a parasite doctor prescribes the exact dosage, here is an overview of the commonly prescribed antiparasitic drugs:

Albendazole: 400 mg
Mebendazole: 100 mg
Praziquantel: 5-10 mg/kg or 600 mg
Ivermectin: 200 mcg/kg
Metronidazole: 250-750 mg
Tinidazole: 2 grams
Nitazoxanide: 500 mg

How long does it take for Ivermectin to get rid of parasites?

Ivermectin starts killing parasites within hours, and most patients feel significant relief within 1 to 2 days. But the full effect and timeline depend on the type of parasite, severity of infection, and your body’s response. For instance, symptoms for intestinal threadworm usually improve within 24-48 hours, whereas lice may take 1-2 days to disappear.
