Mallow + Olopatadine Hydrochloride
Olopatadine Hydrochloride brand names: Pataday, Pazeo.
We found no known interaction between Mallow and Olopatadine Hydrochloride in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Mallow and Olopatadine Hydrochloride
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Olopatadine Hydrochloride and Mallow in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Mallow at all — not against Olopatadine Hydrochloride, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Olopatadine Hydrochloride page
“DMSO is the entry worth reading first for anyone using olopatadine (Pataday, Pazeo). Applied to the skin, DMSO can drive other topical medicines into the body faster and deeper, and since olopatadine is itself a topical antihistamine for itchy, allergic eyes, the concern is that combining the two nearby could amplify both what the drug…”

About Mallow
What is Mallow?
- Sore throat and cough
- Digestive upset
- Skin irritation
- Mild constipation
- Mouth and gum irritation
Mallow (Malva sylvestris) is a traditional herb valued for its soothing, mucilage-rich leaves and flowers, used mostly for sore throat, cough, and minor skin or stomach irritation. Scientific evidence in humans is limited, so it should be seen as a gentle traditional remedy rather than a proven treatment. It is generally considered low-risk for short-term use, but pregnant and breastfeeding people should avoid it due to a lack of safety data.
Malva sylvestris · Malvaceae · Leaves and flowers (sometimes roots) · Tea, dried herb, capsules, liquid extracts, topical preparations, gargles
An interaction check asks whether these two react with each other — it does not ask whether Mallow is a good idea for someone in your situation. Here is what our Mallow record says about it on its own.
Mallow: dosing
There is no standardized, well-established dose for mallow. Traditional use often involves a tea made from a small amount of dried leaves or flowers steeped in hot water.Because products vary widely in strength and form (tea, capsule, or liquid extract), the best approach is to follow the directions on the product label.
