What Kinds of Rashes Cause Blisters?

Rashes are among the most common skin conditions. And while some rashes are mild and temporary, resolving on their own without too much trouble, others become severe and result in blisters. 

At Northstar Dermatology in North Richland Hills, Texas, our expert team of board-certified dermatologists are experts at getting to the source of your rash and providing effective treatment that’s uniquely tailored to your needs.

Read on to learn more about skin rashes that cause blisters, including ways we can help.

Skin rashes that cause blisters

A broad range of rashes can lead to blistering. Some of the more common culprits include:

• Allergic reactions
• Cellulitis, which may start with red, tender, or swollen skin
• Chickenpox and shingles, which stem from viruses 
• Dermatitis herpetiformis, which is linked with celiac disease
• Herpes, which is caused by a virus and can affect your face, genitals, or mouth
• Impetigo, which is caused by bacteria and starts as a small red spot
• Reactions to certain medications, such as penicillin
• Rashes that cause blisters
• Rosacea, which also causes frequent blushing or flushing in your face
• Weeping eczema, which can affect any area of your body

A blistering rash can also derive from the autoimmune disease bullous pemphigoid. Once this disease sets in, your immune system attacks your skin, mistaking it for harmful cells. And while it’s less common than other forms of psoriasis, pustular psoriasis can also cause a blistering rash.

When to seek care for your rash

Whenever you have bothersome or unusual skin symptoms, it’s wise to see a professional. While most rashes aren’t a serious threat, they can become intensely itchy or painful and interfere with your daily life. And some rashes do stem from potentially serious conditions that need treatment.

In particular, seek medical care if your blistering rash appears around your eyes, genitals, or multiple mouth areas. Medical care is also important if your rash coincides with a fever or red streaks in your skin, or if it spreads rapidly. 

Treatment for your blistering rash

Treatment for a rash that causes blisters depends on the underlying cause. After an exam and review of your medical history, we at Northstar Dermatology ask you about your symptoms. We may also perform a skin patch or lab test to rule out or confirm an allergy. 

Depending on the specifics of your condition, your care plan may involve allergy shots, antibiotics, antihistamines, oral medication, or moisturizing creams. We may also recommend home care steps for relief, such as cold compresses.
