Best Medicine To Get Rid Of Cold Sores
Cold sores are a common viral infection that affects millions of people worldwide. These small, painful, and fluid-filled blisters usually appear on the lips, mouth, or nose and can last for up to two weeks. The herpes simplex virus (HSV) causes cold sores, and there are currently no cures for it. However, there are many over-the-counter (OTC) and prescription medications that can help alleviate symptoms and speed up the healing process. Here are some of the best medicines to get rid of cold sores.
1. Abreva
Abreva is an FDA-approved OTC medication that helps shorten the healing time of cold sores. Its active ingredient, docosanol, works by penetrating the skin cells and inhibiting the virus's ability to replicate. When applied at the first sign of a cold sore, Abreva can reduce the duration of the sore by up to 1.5 days. It is available in a cream or pump and can be used up to five times a day.
2. Acyclovir Cream
Acyclovir is a prescription antiviral medication that comes in cream or ointment form. It works by stopping the virus from replicating and can reduce the severity and duration of cold sores. Acyclovir cream should be applied to the affected area five times a day for up to ten days. It is most effective when used at the first sign of a cold sore.
3. Valacyclovir
Valacyclovir is an oral antiviral medication that is available by prescription only. It works by preventing the virus from multiplying and can reduce the frequency, duration, and severity of cold sores. Valacyclovir is usually taken for seven to ten days, depending on the severity of the infection. It is most effective when taken at the first sign of a cold sore.
4. Famciclovir
Famciclovir is another prescription antiviral medication that is used to treat cold sores. It works by stopping the virus from replicating and can reduce the duration and severity of symptoms. Famciclovir is usually taken for seven days and is most effective when taken at the first sign of a cold sore.
5. Lysine Supplements
Lysine is an amino acid that is essential for the body's immune system. Some studies have shown that taking lysine supplements can reduce the frequency and severity of cold sores. Lysine supplements are available over-the-counter and can be taken orally or applied topically to the affected area. It is important to speak with a healthcare provider before taking any supplements.
Conclusion
Cold sores can be uncomfortable and unsightly, but there are many medications available that can help alleviate symptoms and speed up the healing process. Abreva, acyclovir cream, valacyclovir, and famciclovir are all effective prescription medications that can reduce the duration and severity of cold sores.
