Key facts about Stromectol and ivermectin at a glance:

Do you require a prescription for ivermectin?

Ivermectin prescription status in New Zealand

• Ivermectin is a prescription-only medicine in New Zealand, regulated by the Medicines Act (Healthify, NZ health information provider).
• No over-the-counter availability for human use exists (Medsafe Data Sheet).
• A valid prescription from a New Zealand doctor is required to obtain Stromectol from any pharmacy (Ministry of Health letter).

Legal classification of ivermectin (Stromectol)

• Stromectol is the only medicine containing ivermectin approved in New Zealand (Medsafe).
• It is classified as a controlled drug and must be dispensed only on prescription (Medsafe Consumer Medicine Information).
• Special Authority criteria govern funded access, but do not restrict a doctor’s ability to prescribe (Pharmac clarification).

The implication: The prescription barrier exists precisely because ivermectin is a potent antiparasitic with known side effects. Without a doctor’s oversight, the risks outweigh the benefits.

What illnesses does ivermectin cure?

Approved parasitic infections (strongyloidiasis, onchocerciasis)

• Ivermectin is approved for treating intestinal strongyloidiasis (threadworm) and onchocerciasis (river blindness) (Medsafe).
• The drug works by binding to nerve and muscle cells of parasites, causing paralysis and death (DermNet NZ, dermatology resource).
• It may also be used off-label for scabies when other treatments have failed (Medsafe Data Sheet).

Off-label uses and controversies (COVID-19)

• Medsafe has explicitly stated that ivermectin is not approved to prevent or treat COVID-19 in humans (Medsafe alert).
• No clinical evidence supports its use for COVID-19, and regulatory bodies worldwide have issued warnings against self-medication.

The pattern: Approved uses are narrow, evidence-based, and overseen by a doctor. Off-label use for COVID-19 is not just unsupported — it is actively discouraged by New Zealand’s medicines regulator.

What human drugs contain ivermectin?

Stromectol 3 mg tablets

• The only oral human formulation of ivermectin in New Zealand is Stromectol 3 mg tablets (Medsafe CMI).
• Each pack contains 4 tablets, and the active ingredient is ivermectin 3 mg per tablet (Medsafe Data Sheet).
• No other oral brands are approved in New Zealand (Medsafe).

Other formulations (cream, lotion) for topical use

• Topical ivermectin is available as Soolantra cream for rosacea, but it is also prescription-only (DermNet NZ).
• Veterinary ivermectin products (paste, pour-on) are available at farm supply stores like Farmlands, but they are not for human use (Medsafe).

The trade-off: While veterinary ivermectin is easier to obtain, it contains excipients and concentrations not safe for humans. Using it poses serious health risks and is not a substitute for Stromectol.

Where can I get ivermectin for humans?

Chemist Warehouse (Australia) – not directly for NZ

• Chemist Warehouse Australia stocks Stromectol but requires an Australian prescription and does not ship to New Zealand without one (Chemist Warehouse Australia product page).
• Ordering without a prescription would violate New Zealand medicines importation laws.

New Zealand pharmacies (e.g., Pharmacy Direct, Chemist Warehouse NZ online?)

• New Zealand pharmacies such as Pharmacy Direct NZ can dispense Stromectol if you have a valid NZ prescription (Healthify).
• Chemist Warehouse NZ does not list Stromectol on its online store for direct purchase without prescription.
• All dispensing must follow the prescription guidelines set by Medsafe.

Prescription required from a New Zealand doctor

• You must see a GP or specialist to obtain a prescription. Telehealth services may also prescribe if appropriate.
• Prescriptions are typically for a single course of treatment; repeats require further assessment.

The catch: Even if you find a seller online, legal access in New Zealand runs through a doctor. No prescription means no legitimate supply.

What to avoid when taking ivermectin?

Drug interactions

• Avoid alcohol during treatment; it can increase side effects such as dizziness and nausea (Medsafe CMI).
• Use with caution if taking warfarin or other blood thinners — ivermectin may increase their effects (Medsafe Data Sheet).
• Concurrent use with other antiparasitics should only be done under medical supervision (Healthify).

Food and alcohol precautions

• Take Stromectol on an empty stomach with water for best absorption (Medsafe CMI).
• Avoid grapefruit juice as it may interfere with drug metabolism.
• Inform your doctor about all medications and supplements before starting treatment.

Why this matters: Following these precautions isn’t just about avoiding side effects — it’s about ensuring the drug works as intended and doesn’t cause harm that outweighs the benefit.

Ivermectin is used to treat worms that live in the human bowel such as roundworms. Ivermectin kills worms by binding to the nerve and muscle cells of parasites.

Stromectol 3 mg tablet contains 3 mg ivermectin. It is a prescription medicine.

— Medsafe Consumer Medicine Information, NZ medicines regulator

For New Zealanders considering ivermectin, the choice is clear: work with your doctor to determine if a prescription is medically appropriate, or accept that self-sourcing from overseas or veterinary supplies carries real legal and health risks. The regulatory framework exists to protect patients, not to gatekeep — and understanding it is the first step toward safe use.

For those in New Zealand seeking prescription medications, similar guidance applies to tretinoin at NZ Chemist Warehouse, which also requires a doctor’s script before purchase.
