Mupirocin Ointment: An Over-the-Counter Treatment for Bacterial Skin Infections

Introduction

Skin infections are a common problem, affecting millions of people each year. In most cases, these infections are caused by bacteria. While many skin infections can be treated with over-the-counter (OTC) medications, some require prescription antibiotics. Mupirocin ointment is one such OTC medication that is used to treat a variety of bacterial skin infections.

What is Mupirocin Ointment?

Mupirocin ointment is an antibiotic that is effective against a wide range of bacteria, including Staphylococcus aureus (staph) and Streptococcus pyogenes (strep). It is typically used to treat minor skin infections, such as:

• Impetigo
• Folliculitis
• Cellulitis
• Ecthyma
• Erysipelas

Mupirocin ointment is available in two strengths: 2% and 5%. The 2% strength is available OTC, while the 5% strength is available by prescription only.

How Does Mupirocin Ointment Work?

Mupirocin ointment works by inhibiting the growth of bacteria. It does this by binding to a specific enzyme that is essential for bacterial protein synthesis. Without this enzyme, bacteria cannot produce the proteins they need to grow and reproduce.

How to Use Mupirocin Ointment

Mupirocin ointment is typically applied to the affected area three times per day. It is important to clean the area before applying the ointment and to cover the area with a bandage or gauze. The ointment should be used for 7-10 days, or until the infection has cleared.

Side Effects of Mupirocin Ointment

Mupirocin ointment is generally well-tolerated. However, some people may experience side effects, such as:

• Skin irritation
• Redness
• Itching
• Burning
• Stinging

These side effects are usually mild and will usually go away within a few days. If you experience any severe side effects, such as swelling, blistering, or oozing, you should stop using the ointment and see your doctor.

Common Mistakes to Avoid

When using mupirocin ointment, it is important to avoid the following common mistakes:

• Not cleaning the area before applying the ointment. This can increase the risk of infection.
• Not covering the area with a bandage or gauze. This can help to keep the ointment in place and protect the area from further infection.
• Using the ointment for too long. This can increase the risk of side effects.
• Sharing the ointment with other people. This can spread the infection.

Step 2: Apply a thin layer of mupirocin ointment to the affected area. Rub the ointment in gently until it is absorbed.

Step 3: Cover the area with a bandage or gauze. This will help to keep the ointment in place and protect the area from further infection.

Step 4: Repeat steps 2 and 3 three times per day. Continue using the ointment for 7-10 days, or until the infection has cleared.
