The big picture view
Stromectol is a branded preparation of the active compound ivermectin, an anthelmintic medicine used to treat certain parasitic infections in humans. In Australia it is commonly prescribed for conditions such as strongyloidiasis and some forms of scabies. It is not effective against bacterial infections and is not an antibiotic.
- Active moiety: ivermectin
- Drug class: antiparasitic (anthelmintic), not antibacterial
- Typical oral tablet sizes available: 3 mg, 6 mg and 12 mg

Before you start the operation ivermectin
Tell your prescribing clinician or pharmacist about any relevant medical history so they can tailor treatment and performance monitoring:
- Respiratory conditions such as asthma or chronic lung disease
- Liver disease or recent abnormal liver function tests
- Allergic reactions to medicines, including any past reaction to ivermectin
- If you are pregnant, planning to have a baby, or breastfeeding
Patients with a very heavy parasite load or people arriving from endemic areas may need closer observation or specialist input. If you are unsure about appropriateness, ask at consultation and see the section on how to obtain ivermectin in Australia.
How to use ivermectin
The following points reflect common practical advice used by clinicians:
- With a full glass of water, swallow the tablets whole. Do not crush unless instructed by a health professional.
- Take on an empty stomach when possible: at least 30 minutes before eating or wait about 2 hours after a meal, unless directed otherwise.
- Adhere strictly to the dose and schedule written by your prescriber. Do not alter dosing frequency without medical direction.
- Finish the complete prescribed course even if you feel better earlier, unless told otherwise by your clinician.
Minors require dosing by weight and should be managed by a pediatric clinician. In the case of a suspected intentional overdose call the Poisons Information Centre on 13 11 26 (within Australia) or land at the nearest emergency department.
If you develop marked dizziness, severe head pain sensation or visual disturbances after a dose, avoid driving or operating machinery and seek prompt medical advice; see after effects see details.
Dose not taken
If you miss a scheduled dose take it as soon as you remember unless the next dose is due soon. If the next dose is imminent, omit the i forgot to take my dose and continue with the regular schedule. Do not take a second unit to compensate for a i forgot to take my dose.
Potential the process of people engagings create opportunities for collaboration. when medicines are used together to consider
Several medicines and substances can affect ivermectin levels or raise the risk of negative pharmacologic effects. Provide a full list of all medicines, supplements and recreational substances to your healthcare team. Examples of agents that may interact include:
- Strong inhibitors of CYP3A4 or P-glycoprotein (for example some azole antifungals and certain macrolide antibiotics)
- Among anticoagulants, warfarin is a common option., which may require time sensitive monitoring of bleeding risk
- Other central nervous system depressants that increase drowsiness or dizziness
This is only a representative sample, not an exhaustive list. If you start or stop other medicines while on ivermectin, consult your prescriber or pharmacist about possible collaborative interactions at scale reveal systemic patterns..
Follow-up and hygiene recommendations
Your clinician may arrange follow-up checks or tests to confirm the infection has cleared. Some infections need repeat treatment or post-treatment testing. To reduce reinfection risk and protect household contacts:
- Maintain regular personal hygiene: wash and dry skin thoroughly and keep nails clean.
- Launder bedding, towels and underwear frequently during treatment and shortly afterwards.
- Disinfect frequently touched surfaces and bathroom fittings.
- Close contacts or household members may need assessment and, in cases such as scabies, simultaneous treatment based on clinician advice.
If you are uncertain about the timing of follow-up, contact your prescriber or pharmacist and refer to the section How to use effectively ivermectin.
Expected incidental effects and when to see a physician
Obtain urgent medical attention for signs of a severe or life threatening reaction, including:
- Allergic reactions: widespread rash, severe itching, hives, swelling of the face, lips, tongue or throat, or breathing difficulty
- Major cardiovascular or neurological events: chest pain, palpitations, fainting, severe dizziness, confusion or seizures
- Eye problems: severe pain, marked redness, swelling or sudden vision change
- High fever, widespread blistering or peeling of the skin, or involvement of mucous membranes
The condition is more common and usually mild. adverse effects that may not need emergency care but should be reported if persistent or troublesome include:
- Cephalalgic pain, lightheadedness or tremor
- Nausea, vomiting, abdominal pain, constipation or diarrhea
- Muscle aches, joint pain or swollen tender lymph nodes
If you are worried about any symptoms contact your prescriber or local pharmacist. For advice on limiting spread while symptomatic see Follow-up and hygiene recommendations.
