Ivermectin cream: what it treats, how to use it, side effects
Last updated September 3, 2026.
Ivermectin 1% cream (brand name Soolantra) is a once-daily prescription cream for the inflammatory bumps and pimples of rosacea. It is not the horse-paste story; it is a well-tolerated topical that works partly by killing the demodex mites implicated in rosacea.
What does it treat?
The inflammatory lesions of rosacea: the red bumps and pustules, not the background flushing or visible vessels. It fights inflammation and reduces the demodex mite population that colonizes rosacea skin at higher densities than normal. The lotion form (Sklice) is a separate OTC product for head lice; this page is about the prescription face cream.
How do you take it?
Once daily, a pea-size amount for each affected area of the face (forehead, chin, nose, each cheek), spread as a thin layer and kept away from the eyes and lips. It is not for the mouth, eyes, or vagina. Improvement builds over weeks; the trials ran 12 weeks and beyond, so judge it at 2 to 3 months, not 2 weeks. Many people stay on it long-term, and safety data extends past a year of daily use.
Side effects to know
- Common: very few: skin burning and irritation in at most about 1% of trial patients. It is one of the best-tolerated rosacea topicals.
- Serious: none established at topical doses; allergic reactions are theoretically possible with any product.
Who should not take it?
The label lists no contraindications. Safety in children has not been established, and pregnancy and breastfeeding are doctor conversations, since formal studies are limited. If your rosacea is mostly redness and flushing without bumps, this is the wrong tool; brimonidine gel or oxymetazoline cream targets redness instead.
When is it an emergency?
Call 911 for facial swelling, hives, or trouble breathing after application, the rare allergic reaction. Otherwise, worsening rash or eye irritation warrants a call to your prescriber, not an emergency. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Is this the same ivermectin from the news?
Same molecule, completely different product and use. Soolantra is a 1% face cream approved for rosacea bumps, applied to skin in pea-size amounts. It has nothing to do with oral or veterinary ivermectin, and topical absorption through facial skin is minimal.
What do mites have to do with rosacea?
Demodex mites live in nearly everyone's hair follicles, but rosacea skin carries them at much higher densities, and their presence appears to drive the inflammatory bumps. Ivermectin kills the mites and is also directly anti-inflammatory, which is why it works where antibiotics sometimes stall.
How long until my skin clears?
Plan on weeks to months. Trial results were measured at 12 weeks, and many people keep improving through month 3. Early wins in week 2 to 4 happen, but judging the cream before 12 weeks short-changes it. If nothing has moved by 3 months, reassess with your dermatologist.
Can I wear makeup over it?
Yes. Let the cream absorb fully first, then apply cosmetics as usual. It layers fine under moisturizer and sunscreen too; in fact a gentle skincare routine plus daily sunscreen is the backdrop all rosacea treatment sits on.
Will it fix the redness too?
Only partly, and only the redness that comes from inflamed bumps. Persistent background redness and visible vessels are vascular, and ivermectin does not constrict vessels. Brimonidine gel, oxymetazoline cream, or laser treatments address that component; many people need both lanes.
Can I use it forever?
The safety data runs past a year of daily use with adverse reactions in about 1% of users, and dermatologists commonly keep responders on it long-term, since rosacea is chronic. It is a controller, not a cure: stopping usually means the bumps return within months.
