Is Stromectol available without prescription in the UK?
Stromectol (ivermectin) is classified as a Prescription Only Medicine (POM) in the United Kingdom. This means that Stromectol cannot be sold as a General Sales List (GSL) or Pharmacy medicine (P) and requires a valid prescription from a qualified healthcare professional. However, it is possible to purchase generic ivermectin products online through licensed pharmacies offering prescription services. Many reputable online pharmacies allow customers to order Stromectol in the UK provided they complete a medical questionnaire and obtain approval from a UK-registered prescriber. In this way, customers can buy genuine Stromectol online with fast delivery.
What is Stromectol?
Stromectol is the brand name for ivermectin, an antiparasitic medication widely used to treat a variety of internal and external parasitic infections in humans. The active substance, ivermectin, belongs to a class of compounds known as macrocyclic lactones. It was developed in the late 1970s and has since become an essential medicine recognized by the World Health Organization (WHO) for its effectiveness and safety profile. Stromectol is typically used to manage infections such as onchocerciasis (river blindness), strongyloidiasis, scabies and other parasitic infestations.
General information about ivermectin
What is ivermectin?
Ivermectin is an antiparasitic agent that exerts its action by binding selectively to glutamate-gated chloride channels in the nerve and muscle cells of parasites. This binding leads to increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. The drug has a broad spectrum of activity against nematodes (roundworms) and ectoparasites, making it a versatile option for several indications.
History and development
Ivermectin was discovered by Satoshi Ōmura and William C. Campbell and awarded the Nobel Prize in Physiology or Medicine in 2015. Since its introduction, it has transformed global health initiatives, especially in tropical and subtropical regions, through mass drug administration programs aimed at eliminating onchocerciasis and lymphatic filariasis.
Pharmacological classification
Ivermectin is classified pharmacologically as an endectocide. It differs from traditional antibiotics or antivirals in that it specifically targets invertebrate parasites. Stromectol is the marketed human form of ivermectin; veterinary formulations exist but should never be used by humans due to dosing and purity differences.
Why is generic ivermectin cheaper?
Once patent protections expire, multiple manufacturers can produce generic ivermectin, driving competition and lowering costs. Generic Stromectol contains the same active ingredient at the same dosage strength as the brand product, meeting strict regulatory standards for quality, safety and efficacy in the UK. Purchasing generic ivermectin is often the most cost-effective option.
How ivermectin works
Mechanism of action
Ivermectin binds to specific chloride channel receptors in the nerve and muscle cells of parasites. This interaction hyperpolarizes the cell membrane, causing paralysis of the parasite and preventing it from feeding or reproducing. Over time, the immobilized parasite dies and is eliminated by the host’s immune system.
Pharmacokinetics
After oral administration, ivermectin is absorbed into the bloodstream and distributed widely throughout the body. Peak plasma concentrations are reached approximately 4 hours post-dose. The drug has a long plasma half-life of around 12–36 hours, allowing for single-dose regimens in many indications. Ivermectin is metabolized in the liver via CYP3A4 and excreted largely unchanged in faeces.
Onset and duration of effect
The onset of antiparasitic action occurs within hours of administration as ivermectin reaches effective concentrations in the bloodstream and tissues. Depending on the parasite burden and species, a single dose may suffice, though some conditions require repeated dosing days or weeks apart.
Does ivermectin work against all parasites?
No. While ivermectin has broad activity against many nematodes and arthropods, it is not effective against all helminth infections. For example, it has limited activity against tapeworms and flukes, which require different classes of antiparasitic agents.
Price and availability information
How much does Stromectol cost in the UK?
Prices for prescription ivermectin products can vary depending on the pharmacy, formulation and pack size. Branded Stromectol may be more expensive than generic ivermectin preparations. To obtain an accurate price, contact NHA Pharmacy or check our online ordering system. We strive to offer competitive and cheaper options for generic ivermectin without compromising quality.
Why can prices vary?
Several factors influence final cost: the manufacturer, formulation (tablet strength), pack size, wholesale pricing, distribution and pharmacy dispensing fees. Online pharmacies may offer discounts for bulk orders or loyalty schemes, resulting in a lower price per tablet.
| Product | Strength | Formulation | Approximate Price | Status | Note |
|---|---|---|---|---|---|
| Stromectol | 3 mg | Film-coated tablets | From £25 | Prescription required | Brand-name, pack of 6 |
| Generic ivermectin | 3 mg | Tablets | From £18 | Prescription required | Cheaper generic, pack of 6 |
| Generic ivermectin | 6 mg | Tablets | From £30 | Prescription required | Higher strength, cheaper per mg |
Strengths, formulations and pack types
Available strengths
Ivermectin products in the UK are typically available as 3 mg, 6 mg or 12 mg tablets. The dose prescribed depends on patient weight and the specific condition being treated. Dosage regimens for onchocerciasis often involve a single dose of 150 µg/kg repeated annually, whereas treatment for strongyloidiasis usually requires 200 µg/kg as a single dose or two consecutive doses.
Formulations
The most common form is an oral tablet, either film-coated or uncoated. Some compounding pharmacies may offer ivermectin as a liquid formulation for patients unable to swallow tablets. All products must meet MHRA standards for bioequivalence and stability.
Pack sizes
Standard pack sizes include 6, 12 or 24 tablets, although some pharmacies can dispense exact quantities based on a prescription. The pack size can affect price per tablet. Larger packs generally offer cheaper per-unit pricing but may be limited by clinical guidance on treatment duration.
| Feature | Why it matters |

| Formulation | Ease of administration and absorption |
| Pack size | Cost-effectiveness and treatment duration |
| Generic vs branded | Price difference and availability |
Generic and branded interchangeability
When approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA), generic ivermectin is considered therapeutically equivalent to branded Stromectol. Differences are limited to inactive ingredients and tablet appearance. Generic products offer significant price advantages for patients and healthcare systems.
Human parasitic infections
Onchocerciasis (river blindness)
Onchocerciasis is caused by the filarial worm Onchocerca volvulus. Stromectol is administered annually to kill microfilariae in the skin and eyes, reducing transmission by blackfly vectors. Mass drug administration programs use ivermectin to control and eliminate river blindness in endemic regions.
Strongyloidiasis
Strongyloidiasis, caused by Strongyloides stercoralis, can lead to chronic gastro-intestinal and cutaneous symptoms. Single or two-dose regimens of ivermectin effectively eradicate the parasite. Early treatment is critical to prevent hyperinfection in immunocompromised individuals.
Scabies and ectoparasites
Off-label use of ivermectin can treat scabies infestations, especially crusted scabies or outbreaks where topical therapy is impractical. A single oral dose may be followed by a repeat dose after 7–14 days.
Other indications
Ivermectin has been used off-label for lice and other arthropod infestations. Clinical guidelines vary, and specialist advice should be sought. Research continues into novel applications, but only licensed indications should guide prescribing in the UK.
UK legal classification: POM and P
Prescription Only Medicine (POM)
Stromectol is a POM, requiring a prescription from a GP, specialist or other prescriber with UK prescribing rights. This classification ensures proper diagnosis, dosing and monitoring for safety.
Pharmacy medicine (P) vs GSL
Ivermectin does not have a Pharmacy or GSL classification in the UK. Unlike some antitussives or antacids available OTC, Stromectol must be prescribed. Online pharmacies may supply ivermectin without a paper prescription but only after a remote consultation and prescriber approval.
Regulation and oversight
The MHRA regulates all medicines in the UK, overseeing classification, safety monitoring and licensing. Reclassification from POM to a lower category is rare for potent antiparasitic drugs due to the need for clinical assessment before use.
Alternatives to Stromectol
Albendazole
Albendazole is another broad-spectrum anthelmintic used for various worm infections. It is especially effective against tapeworms and some nematodes. In some cases, albendazole is used in combination with ivermectin to enhance efficacy against filarial infections.
Mebendazole
Mebendazole treats common intestinal worms, including pinworm, roundworm and whipworm. It is less effective for filarial infections compared with ivermectin, but it can be used for mixed parasitic loads in certain clinical scenarios.
Topical treatments
For scabies or lice, topical permethrin or malathion preparations are standard. Oral ivermectin may be reserved for cases unresponsive to topical therapy or where large-scale outbreaks occur.
Why choose ivermectin?
Ivermectin’s single-dose or short-course regimens, broad spectrum of activity and favourable safety profile make it a preferred choice for several parasitic diseases. Its systemic action complements topical alternatives for skin infestations.
Stromectol compared with other antiparasitic medicines
| Feature | Stromectol (ivermectin) | Albendazole | Mebendazole |
| Drug class | Macrocyclic lactone | Benzimidazole | Benzimidazole |
| Main mechanism | Paralysis of parasite nerve/muscle | Inhibits microtubule formation | Inhibits microtubule formation |
| OTC availability | No (POM only) | No (POM only) | No (POM only) |
| Prescription uses | Wide, including scabies, strongyloidiasis | Wide, including neurocysticercosis | Common worms, mixed infections |
| Dose regimen | Single or two doses | 1–3 days | 1–3 days |
Choosing the right agent
The choice depends on the parasite species, patient factors, local resistance patterns and clinical guidelines. Specialist advice may be needed for complex or mixed infections.
Food, alcohol and lifestyle considerations
Can ivermectin be taken with food?
Administration with food, especially a moderate-fat meal, can increase absorption of ivermectin. Check product information for specific recommendations. Taking the dose consistently with or without food can help maintain predictable drug levels.
Alcohol interaction
Ivermectin has no direct contraindication with moderate alcohol intake, but alcohol may exacerbate side effects such as dizziness or headache. Patients should avoid excessive alcohol consumption during treatment.
Pregnancy and breastfeeding
Use in pregnancy is not broadly recommended due to limited human data. Breastfeeding mothers should consult a healthcare professional before use, as ivermectin is excreted in breast milk in small amounts.
Weight and dosing
Dose calculations are weight-based. Patients should provide accurate weight information during remote consultations to ensure correct prescribing and avoid under- or overdosing.
Side effects and tolerability
Common side effects
Most patients tolerate ivermectin well. Common adverse reactions include:
- Dizziness
- Fatigue
- Gastrointestinal symptoms: nausea, abdominal pain, diarrhoea
- Skin rash or itching (especially in scabies treatment)
Serious reactions
Rare but serious events include:
- Hypotension
- Neurological effects: confusion, seizures (very rare)
- Severe hypersensitivity or Stevens-Johnson syndrome
Jarisch–Herxheimer reaction
Rapid parasite death can trigger inflammatory responses in some patients, leading to fever, headache and muscle aches. This is usually self-limiting but may require symptomatic treatment.
| Area | Examples |
| Neurological | Dizziness, headache, somnolence |
| Gastrointestinal | Nausea, vomiting, diarrhoea |
| Dermatological | Rash, itching |
| Cardiovascular | Rare hypotension |
Long-term use and resistance
Why is long-term ivermectin use rare?
Chronic or repeated use is generally limited to mass drug administration programs for filarial diseases. Individual patients usually require only one or two doses per treatment cycle. Prolonged exposure may increase the risk of resistance.
Resistance concerns
Although ivermectin resistance has emerged in veterinary medicine, there is limited evidence in human parasites. Continued monitoring and appropriate use are essential to preserve efficacy. Combination therapy or rotating drugs may be employed in high-resistance settings.
Follow-up and review
Patients should have follow-up assessments for symptom resolution and possible side effects. Repeat dosing should be guided by clinical findings and parasitological tests rather than routine prophylaxis.
Warnings, contraindications and interactions
Who should be cautious?
- People with severe liver impairment;
- Patients with compromised blood–brain barrier (e.g., meningitis);
- Individuals on CYP3A4 inhibitors (e.g., ketoconazole);
- People with known hypersensitivity to ivermectin or macrocyclic lactones;
- Pregnant or breastfeeding women (consult a specialist).
Drug interactions
Ivermectin is metabolized by CYP3A4. Concomitant use of strong CYP3A4 inhibitors or inducers may alter plasma levels. Clinical monitoring or dose adjustment may be required.
Contraindications
Severe hypersensitivity reactions to any component of the formulation. Use is contraindicated in children weighing less than 15 kg due to limited safety data.
Why are warning symptoms important?
Alarm symptoms such as severe neurological effects or signs of systemic hypersensitivity require immediate medical attention and discontinuation of ivermectin.
Additional information about Stromectol
What does “generic ivermectin” mean?
Generic ivermectin is the same active substance as branded Stromectol. It must demonstrate bioequivalence to the reference product and meet the same quality, safety and efficacy requirements. Choosing generic can significantly reduce the price per dose.
Why do different products have different leaflets?
Even with the same active ingredient and strength, products may differ in excipients, pack presentations and authorised indications. Always read the patient information leaflet supplied with your medicine.
