Poison Ivy & Treatments In The Hattiesburg-Laurel Area
Lauren Aycock, FNP-BC • July 17, 2018
Southern Mississippi is an outdoorsman’s paradise. During the summer time we do everything from fishing, hiking, camping, to building forts in the woods with our kids. We are blessed to have such exposure to nature and the great outdoors. Anyone who has lived in Mississippi long enough has had a run in with, or knows someone who has, with poison ivy or poison oak. You don’t need a dermatologist to tell you that this is experience is extremely uncomfortable and borderline unbearable. The rashes caused are not contagious, but there may be instances where you may need to make a visit to one of our clinics. In this blog we’ll discuss some treatment options, how to prevent contact with the poisonous plant, and also discuss briefly about potential diseases that may be mistaken for poison ivy rashes.
Poison ivy rash is caused by an allergic reaction to an oily resin called urushiol (u-ROO-she-ol). This oil is in the leaves, stems and roots of poison ivy, poison oak and poison sumac. The itchy, blistering rash often does not start until 12 to 72 hours after you come into contact with the oil. The rash is not contagious and does not spread. Sometimes it may appear as though it spreads but what is actually occurring is a delayed reaction to the poison. So, if you think it is spreading don’t panic, it is not. Most individuals see the rash go away in a few weeks. There are instances where a person can have a severe or serious reaction. If you have a serious reaction, you need to see a doctor right away. Swelling is a sign of a serious reaction — especially swelling that makes an eye swell shut or your face to swell. If you find that this is the reaction you are experiencing then you should find the nearest dermatology clinic or, if it is afterhours, the nearest Urgent Care. In even rarer instances you may be experiencing difficulty breathing after coming into contact with poison ivy, and if this is the case you should go to the emergency room immediately.
What you see and feel on your skin is caused by urushiol. Urushiol is the oil in poison ivy, oak, and sumac. You find this oil in all parts of the plants — the leaves, stems, and even the roots! Within minutes of contact with poisonous oil, the skin starts to absorb it. But you don't feel this, and you don't see a rash right way, because the rash is a delayed reaction to the oil. Wash your skin right away if you come into contact with this oil, unless you know you're not sensitive to it. Washing off the oil may reduce your chances of getting a poison ivy rash. If you develop a rash, it can be very itchy and last for weeks. If you have a reaction to the oil, you can have these signs (what you see) and symptoms (what you feel):
- Itchy skin.
- Redness or red streaks.
- Hives
- Swelling
- An outbreak of small or large blisters, often forming streaks or lines.
- Crusting skin (after blisters burst).
Often the rash looks like a straight line because of the way the plant brushes against your skin. But if you come into contact with a piece of clothing or pet fur that has urushiol on it, the rash may be more spread out. You can also transfer the oil to other parts of your body with your fingers shortly after coming into contact with the oil, which is why it will later appear to spread even though it does not. The reaction usually develops 12 to 72 hours after exposure and lasts two to three weeks. If you have come into contact with a large quantity of the poison ivy, however, the rash may develop sooner.
So, what treatment options are available for these rashes? As stated above, if you are experiencing severe symptoms then you should seek immediate care from either an emergency room or Urgent Care. You can treat mild cases of poison ivy rash at home with soothing lotions and cool baths. You may need prescription medication for a rash that's severe or widespread — especially if it's on your face or genitals. If you have a serious reaction, you will likely need prescription medicine. This is where a dermatologist can intervene. We may prescribe a steroid ointment that you can apply to the skin. To treat a severe case, a strong medicine like prednisone may be necessary. If you have an infection, your dermatologist may prescribe an antibiotic as well. You likely have an infection if you develop a fever or have pus, pain, swelling, and warmth around the rash. Lastly, if you are not sure what caused your rash, you should see a dermatologist. Rashes appear on the skin for many reasons, and the one you are experiencing may not be from poison ivy. Interestingly, there are a couple other conditions that can be misdiagnosed by other providers, with allergic contact dermatitis and chemical rashes being the most commonly confused conditions. In general, if your rash is not improving after seven to 10 days, or you think your rash may be infected, see a Pine Belt Dermatology provider. We can treat your rash and any infection and help relieve the itch.
Below are some tips for dealing with ivy rashes:
- Immediately rinse your skin with lukewarm, soapy water. If you can rinse your skin immediately after touching poison ivy, poison oak, or poison sumac, you may be able to rinse off some of the oil. If not washed off, the oil can spread from person to person and to other areas of your body.
- Wash your clothing. Thoroughly wash all of the clothes you were wearing when you came into contact with the poisonous plant. The oil can stick to clothing, and if it touches your skin, it can cause another rash.
- Wash everything that may have the oil on its surface. Besides clothing, the oil from poison ivy, poison oak, and poison sumac can stick to many surfaces, including gardening tools, golf clubs, leashes and even a pet’s fur. Be sure to rinse your pet’s fur, and wash tools and other objects with warm, soapy water.
- Do not scratch, as scratching can cause an infection.
- Leave blisters alone. If blisters open, do not remove the overlying skin, as the skin can protect the raw wound underneath and prevent infection.
- Take short, lukewarm baths. To ease the itch, take short, lukewarm baths in a colloidal oatmeal preparation, which you can buy at your local drugstore. You can also draw a bath and add one cup of baking soda to the running water. Taking short, cool showers may also help.
- Consider calamine lotion or hydrocortisone cream. Apply calamine lotion to skin that itches. If you have a mild case, a hydrocortisone cream or lotion may also help.
- Apply cool compresses to the itchy skin. You can make a cool compress by wetting a clean washcloth with cold water and wringing it out so that it does not drip. Then, apply the cool cloth to the itchy skin.
- Consider taking antihistamine pills. These pills can help reduce itching, however use with caution. You should not apply an antihistamine to your skin, as doing so can worsen the rash and the itch.

At Pine Belt Dermatology & Skin Cancer Center, we believe education is key to protecting and maintaining healthy skin. July is significant for skin health, featuring both UV Safety Awareness Month and World Skin Health Day on July 8 . These occasions highlight the importance of sun protection and raise awareness of common concerns, such as hyperpigmentation and melasma . Understanding how ultraviolet (UV) exposure affects your skin helps prevent long-term damage and supports a healthier, more even complexion. Why UV Protection Matters The sun emits ultraviolet rays that can damage skin even on cloudy days. While many associate UV exposure with sunburn, its effects are broader. Repeated UV exposure accelerates skin aging, increases skin cancer risk, and contributes to pigmentation disorders. Common effects of excessive UV exposure include: • Sunburn and skin irritation • Premature aging, including fine lines and wrinkles • Dark spots and uneven skin tone • Increased risk of skin cancer • Worsening of hyperpigmentation and melasma Daily sun protection is one of the most effective ways to maintain healthy skin and reduce preventable damage. What Is Hyperpigmentation? Hyperpigmentation is a common condition where areas of skin become darker than the surrounding tissue due to excess melanin production. Multiple factors can contribute to hyperpigmentation, including: • Sun exposure • Acne scars and inflammation • Hormonal changes • Skin injuries or irritation • Certain medications While hyperpigmentation is mostly harmless, many seek treatment to improve skin tone as well as restore confidence. Understanding Melasma Melasma is a type of hyperpigmentation that shows up as brown or gray-brown patches, typically on the cheeks, forehead, nose, and upper lip. Melasma is frequently associated with: • Hormone changes during pregnancy • Birth control medications • Hormone replacement therapy • Genetic predisposition • Sun exposure Although melasma is not dangerous, it can be difficult to treat because UV exposure frequently triggers or worsens it. Even minimal sun exposure can increase pigment production and make discoloration more noticeable. Protecting Your Skin from UV Damage Whether you are concerned about skin cancer, hyperpigmentation, or melasma, daily sun protection is essential. Dermatologists suggest: • Using sun lotion with SPF 30 or higher every day • Reapplying sunscreen every two hours when outdoors • Wearing wide-brimmed hats and protective clothing • Seeking shade during peak sunlight hours • Wearing UV-protective sunglasses • Avoiding tanning beds Consistent sun protection helps prevent new pigmentation issues. World Skin Health Day: A Reminder to Prioritize Skin Care Observed annually on July 8, World Skin Health Day encourages preventive steps to maintain healthy skin. This is a reminder to perform regular self-exams, schedule dermatology visits, and address concerns early. If you notice persistent dark spots, changes in pigmentation, or new skin lesions, seek an expert assessment to determine the cause and identify treatment options. Supporting Healthy Skin Year-Round UV Safety Awareness Month and World Skin Health Day remind us that protecting your skin is an investment in long-term health. Practicing sun safety and understanding conditions like hyperpigmentation and melasma help preserve your skin’s health, appearance, and function.

When a ‘Rash’ Might Be Something More Serious At Pine Belt Dermatology & Skin Cancer Center, we recognize that rashes are common and frequently resolve quickly with minimal treatment. However, some rashes may signify underlying conditions that require prompt medical attention. Identifying when a rash is more than a minor irritation is key to protecting your health. Comprehending Common vs. Concerning Rashes Most everyday rashes result from irritants, allergies, heat, or minor infections and typically improve within a few days with over-the-counter treatments. However, if a rash lasts longer, worsens, or appears with other symptoms, it may signal a more serious issue. Identifying the difference between a routine rash and one that requires medical evaluation helps avoid complications and ensure appropriate care. Warning Signs to Watch For Certain features may indicate a rash requires clinical assessment, including: Rapidly spreading or worsening rash Severe pain, swelling, or blistering Signs of infection such as pus, warmth, or red streaks Fever or flu-like symptoms accompanying the rash A rash that does not improve after several days of treatment Dark, purple, or bruised-looking areas on the skin For example, a rash with fever may indicate a viral or bacterial infection, whereas painful blistering can suggest conditions such as shingles. In rare cases, rashes may signal autoimmune disorders or severe allergic reactions. Rashes That May Point to Underlying Conditions Some rashes may be linked to broader health concerns, including conditions that cause inflammation in the skin and other organs: Allergic reactions that may escalate into further severe responses Infections that spread beyond the skin if untreated Medication reactions that require immediate adjustment Persistent or unusual skin changes may be early signs of skin cancer or precancerous conditions, especially if they do not heal or continue to change over time. Why Early Evaluation Matters Delaying care for a worrisome rash may allow the underlying condition to progress. Early diagnosis improves treatment outcomes and helps prevent discomfort and complications. A dermatology specialist can assess the rash’s appearance, location, and progression, and may recommend diagnostic tests if needed. This approach assures treatment addresses the underlying cause, not just the visible symptoms. When to See a Dermatology Specialist If you are unsure about your rash, it is best to err on the side of caution. Consider seeking care if: The rash is persistent, painful, or unusual in appearance Over-the-counter treatments are not effective You experience additional symptoms such as fever or fatigue The rash interferes with your daily comfort or quality of life At Pine Belt Dermatology & Skin Cancer Center, our experienced providers supply comprehensive skin evaluations and customized treatment plans. We take time to understand your symptoms and deliver clear, effective solutions tailored to your needs. Protecting Your Skin and Your Health While many rashes are minor, some may be early warning signs of more serious health concerns. Monitoring skin changes and pursuing prompt medical advice can produce a notable effect. If you notice a rash that does not seem right, do not ignore it. Schedule a consultation with Pine Belt Dermatology & Skin Cancer Center for expert evaluation and peace of mind. Your skin is an important indicator of your overall health, and taking it seriously supports ongoing well-being.
