Prince George – If you’ve ever dealt with a cold sore, you know just how uncomfortable and inconvenient they can be. Thankfully, many cases can be treated quickly and safely, often without a doctor’s visit, according to pharmacists. In this article, we’ll delve into what triggers cold sores, how they spread, and the assistance your local pharmacy can provide.

Cold sores are small, painful blisters that usually crop up along the edge of the lip, and the herpes simplex virus causes them. For many people, outbreaks aren’t just a matter of chance; factors such as stress, illness, and excessive sun exposure can trigger them.

However, not everyone is vulnerable to this virus right away. You first need to be exposed to it. For instance, coming into contact with someone else’s cold sore and then touching your face can significantly increase your chances of developing one later.

When it comes to treating cold sores, you might have noticed various over-the-counter remedies at the pharmacy. Products like Abreva can offer some relief, and pharmacists frequently get questions about them.

Cold sores are generally categorized as minor ailments, which means pharmacists are equipped to provide treatment with prescription medications. Before recommending any treatment, they’ll ask a series of questions to understand your symptoms, rule out other issues, and ensure that the treatment is both safe and suitable.

Not every case qualifies for pharmacy treatment, though. If you have any underlying health concerns, your pharmacist may direct you to a doctor for further evaluation. 

Once a cold sore has fully formed, it can be more challenging to treat. Some medications can help lessen the duration of an outbreak, but they work best when started at the very first sign of tingling or discomfort.

Pharmacists focus on assessing your symptoms, pinpointing the proper treatment, and helping you get ahead of the next outbreak before it fully sets in.
