As of 2016, there are no retailers that sell Zilactin-L cold sore relief gel or liquid, as Zilactin-L has been discontinued, states Pharmapassport. The brand only offers Zilactin early relief cold sore gel and Zilactin-B, reports Blairex. These medicines are available nationwide at major retailers, including CVS, Walgreens, Walmart and Rite Aid. The medications can also be purchased online from retailers such as Amazon.com, Drugstore.com and Pharmapacks. The price of Zilactin varies at each retailer.
Zilactin early relief cold sore gel is for treating cold sores and fever blisters, notes Blairex. It is formulated to alleviate pain for up to six hours. The treatment dries clear to avoid detection on the mouth area. Zilactin-B treats sores insides the mouth, including canker sores. The remedy allows pain-free eating and drinking for up to six hours.
These gels provide a thin protective layer when applied, notes Pharmapacks. It seals the medication in to promote healing, and it seals out irritants. This protective layer must not be peeled off, as it may result in irritated or damaged skin. Consult a doctor before using Zilactin on children under 2 years old. Zilactin-B side effects include a fast heart rate, headache and confusion, states Drugs.com. Do not use on large areas of skin, and use the smallest amount possible. Symptoms normally clear up after seven days.
