Allergy eye drops you can use as often as needed without the risk of side effects*. We all want our eyes to feel better during allergy season, but many allergy sufferers are concerned about the chemicals found in allergy eye drops. Traditional over-the-counter allergy drops use chemicals such as vasoconstrictors to mask symptoms. Vasoconstrictors may actually worsen the symptoms if used more than directed (usually 4 times a day maximum). Similasan of Switzerland works differently, by using natural botanical extracts used for over 200 years to stimulate the body's natural defenses and target the root cause, so you can feel temporary relief without harsh chemicals. Go ahead, use as often as needed. Trusted by pharmacists and families in Switzerland for over 35 years, Similasan is a leading Swiss brand of remedies that use natural active ingredients instead of harsh chemicals to keep families healthy. Our state of the art facility located near the Swiss Alps makes over 190 popular remedies for children and adults: cough and cold, eye care, ear care, nasal allergies and more. Similasan has been voted by the readers of Reader's Digest the most trusted Swiss healthcare brand 14 years in a row.*The uses of our products are in compliance with official Homeopathic Compendia.
