Similasan Pink Eye Relief is an over-the-counter homeopathic eye drop sold in a 10 ml (0.33 fl oz) bottle. The Swiss brand markets it for the redness, burning, watery discharge, and gritty feeling that come with pink eye. This Similasan Pink Eye Relief review checks the claims against the evidence.
The formula uses belladonna, eyebright, and Hepar sulfuris at extreme homeopathic dilutions. Shoppers rate the drops highly, with 4.8 stars on Instacart and 4.7 on Target. But the FDA sent Similasan a warning letter in September 2023, and no independent trial shows the drops treat conjunctivitis.
Our team at Optimal Weight Plan walks through what the bottle contains, what reviewers report, what the FDA said, and what the price buys. By the end, you'll know whether the drops fit your situation and when a doctor visit makes more sense.
What Is Similasan Pink Eye Relief?
Similasan Pink Eye Relief is a sterile homeopathic eye drop that targets the symptoms of pink eye, not the cause. The label lists redness, burning, watery discharge, and a sensation of grittiness. The bottle holds 10 ml, and a Canadian pharmacy lists it at $17.99.
The brand pitches the drops as a gentle option for the whole family. Its marketing contrasts the formula with vasoconstrictor drops, which can worsen redness when overused. To be clear, a gentle formula and a proven formula are two different things.

Who Makes Similasan Pink Eye Relief?
Similasan AG manufactures the drops at its facility in Switzerland. The company sells a wide line of homeopathic eye products, including dry eye, allergy, stye, and computer eye formulas. Pink Eye Relief sits in that range beside a kids version and a nighttime gel.
The FDA inspected that Swiss facility and cited current good manufacturing practice violations in its 2023 warning letter. Does that mean every bottle is unsafe? Not necessarily, but it's a fact buyers deserve to know before they put anything in their eyes.
What Is in Similasan Pink Eye Relief?
Similasan Pink Eye Relief contains three homeopathic active ingredients: Atropa belladonna 6X, Euphrasia officinalis (eyebright) 6X, and Hepar sulfuris calcareum 12X. A Canadian pharmacy listing shows these actives. Check your own box, since formulas and labels can differ by country.
The inactive list on that same listing includes purified water, sodium nitrate, borax, and boric acid as buffering agents. Silver sulfate appears as a preservative. The FDA letter flagged silver sulfate, because long-term silver exposure can tint skin and eyes gray or blue-gray.
Listed Ingredients:
- Atropa belladonna 6X (whole plant)
- Euphrasia officinalis, eyebright 6X (whole plant)
- Hepar sulfuris calcareum 12X (calcium sulfide)
- Purified water, sodium nitrate, borax, boric acid
- Silver sulfate as a preservative
What Do the Homeopathic Ingredients Mean?
The 'X' scale shows how many times the original substance was diluted by a factor of ten. A 6X dilution means one part in a million. A 12X dilution means one part in a trillion. Dilutions this large leave very little of the original plant in the bottle.
Homeopathy rests on the idea that 'like cures like'. Mainstream medicine has not validated that principle. Retailer pages themselves state that the claims rest on traditional homeopathic practice, not accepted medical evidence.
How Does Similasan Pink Eye Relief Work?
Similasan says the drops stimulate the body's natural defenses to relieve pink eye symptoms temporarily. The marketing avoids harsh chemicals and vasoconstrictors. No published mechanism shows how a 6X or 12X dilution would act on the eye surface.
The inactive base is sterile water with buffering salts. A sterile liquid can rinse the eye and feel soothing. Is that the same as treating an infection? No. Rinsing comforts the eye, but viral and bacterial conjunctivitis need time or antibiotics to clear.
How Do You Use Similasan Pink Eye Drops?
A Canadian pharmacy listing gives the adult and child dose as 2 to 3 drops per eye as needed. The same listing says to continue until symptoms improve. Follow the directions printed on your own package, because labels vary by market.
Contact lens wearers have a clear rule. The listing says the drops are safe with lenses, but it advises leaving lenses out until symptoms subside. The label also warns that sharing a bottle between people can spread infection.
Basic Steps:
- Wash your hands before you touch the bottle.
- Remove contact lenses and keep them out until symptoms clear.
- Tilt your head back and pull the lower lid down.
- Squeeze the listed number of drops without touching the tip to your eye.
- Cap the bottle and keep it for one person only.
Does Similasan Pink Eye Relief Actually Work?
No clinical evidence shows that Similasan Pink Eye Relief cures or treats conjunctivitis. Our research found no independent trial of these specific dilutions for pink eye. The reported relief comes from user stories, which are anecdotes, not controlled results.
Here's the part most people miss. Most pink eye gets better by itself. The CDC says viral pink eye usually clears in 7 to 14 days. Mild bacterial pink eye often clears in 2 to 5 days. So did the drops work, or did time work? You can't tell from a single bottle.
Does Similasan Help with Viral or Bacterial Pink Eye?
No. The drops do not kill viruses or bacteria. Antibiotics do not help viral pink eye, and a homeopathic drop has no antimicrobial claim behind it. Bacterial cases with pus may need a prescription from a doctor.
Allergic pink eye follows a different rule. Removing the trigger is the main step, and allergic pink eye is not contagious. A soothing sterile drop may ease comfort in that case, but the label still can't promise a treatment effect.
See a doctor if you have eye pain, light sensitivity, or blurred vision that doesn't clear after wiping. Contact lens wearers should call an eye care professional if symptoms don't improve within 12 to 24 hours. That advice comes from the CDC.
What Do Similasan Pink Eye Relief Reviews Say?
Customer reviews of Similasan Pink Eye Relief skew strongly positive across major retailers. Instacart shows 4.8 out of 5 stars from 110 reviews. Target lists 4.7 stars from 298 ratings. Walmart lists 4.5 stars. Those scores show satisfaction, not proof of treatment.
iHerb summarizes the feedback as mixed but leaning favorable. Many users report relief from redness, dryness, and irritation. Retail star ratings come from people who chose to review, and they can't separate the drops from the natural course of the illness.
What Do Happy Customers Report?
Happy buyers describe soothing, fast comfort after using the drops. One Instacart reviewer says the drops helped her feel better within minutes. Another says they helped multiple times when something was in the eye or after eye strain.
A parent on Influenster says discharge and irritation cleared quickly while redness lingered. The same parent reported the child's pink eye gone in about 2 days. That timeline fits the normal course of mild bacterial pink eye. Interesting, right?
What Are the Common Complaints?
Critics report irritation, no benefit, and awkward packaging. One eBay buyer said the drops did not help dry eyes and actually irritated them. The label itself warns that symptoms may briefly worsen at first. Some sources note the bottle is hard to squeeze.
The label also tells parents that children with conjunctivitis should see a physician. Why does that matter? A drop labeled for all ages can tempt a parent to skip the doctor. For a child, skipping the visit is the real risk.
Is Similasan Pink Eye Relief Safe?
Yes, mostly, but with real caveats. Similasan Pink Eye Relief is sterile and widely sold, yet it has regulatory and manufacturing questions attached. The FDA stated that people should not use ophthalmic products labeled as homeopathic, because they should not be marketed. Any drug used in the eyes must be sterile to reduce infection risk.
The main safety risk is delay. Pink eye can mask a more serious problem like a corneal infection. The bottle can also spread infection if two people share it. The good news? Reports of direct harm from this product are not common in our research.
Did the FDA Warn Similasan?
Yes. The FDA issued a warning letter to Similasan AG on September 11, 2023. It named 12 products, including Pink Eye Relief, Kids Pink Eye Relief, and Pink Eye Nighttime Gel. The agency treated them as unapproved new drugs marketed with claims to treat eye disease.
The letter also cited current good manufacturing practice violations at the Swiss facility. That was part of a wider action that included CVS and Walgreens products. In plain English: the FDA says these drops make treatment claims without approval.
Who Should Avoid Similasan Pink Eye Relief?
Anyone with severe symptoms should skip self-treatment and see an eye doctor. That includes eye pain, light sensitivity, blurred vision, intense redness, or symptoms that get worse. A weakened immune system also calls for medical care.
Parents of children with conjunctivitis should follow the label and call a physician. Contact lens wearers with symptoms need a prompt exam. People with a known allergy to belladonna, eyebright, or any listed ingredient should avoid the drops.
See a Doctor If You Have:
- Eye pain or a feeling of something stuck in the eye
- Light sensitivity or blurred vision
- Thick pus or discharge
- Symptoms that worsen or last beyond a week
- A child with conjunctivitis symptoms
- A weakened immune system or contact lenses
How Much Does Similasan Pink Eye Relief Cost?
Similasan Pink Eye Relief costs around $17.99 for a 10 ml bottle on one Canadian pharmacy listing. US prices vary by store and change often. Check Walmart, Target, Amazon, iHerb, and Instacart for the current number before you buy.
Shoppers find it in major drugstores, big-box retailers, and online shops. Availability is broad, which makes it easy to grab on impulse. Easy access is exactly why the evidence matters so much.
Is Similasan Pink Eye Relief Worth the Price?
No, not as a treatment. At about $17.99, the price buys a sterile soothing drop with no proven effect on the infection. Plain preservative-free artificial tears cost less and have clearer evidence for comfort. Pink eye needs time, hygiene, or a doctor.
Here's the bottom line. If you already like the drops and your symptoms are mild, the risk is low. Just don't expect the bottle to shorten the illness. Spend on a doctor visit if symptoms look serious.
