The lidocaine (TOP) drug label does not provide specific guidance for the treatment of severe sunburn pain. However, it does mention that the product should not be used on irritated or swollen skin, which may be present in cases of severe sunburn. It also advises to discontinue use and consult a doctor if symptoms persist or if skin injury occurs. Therefore, it is recommended to consult a doctor for appropriate treatment of severe sunburn pain, as lidocaine (TOP) may not be suitable for this condition 1.
From the Research
To treat severe sunburn pain, take over-the-counter pain relievers like ibuprofen (Advil, Motrin) 400-600mg or acetaminophen (Tylenol) 500-1000mg every 6-8 hours as needed to reduce pain and inflammation. According to the most recent study 2, non-steroidal anti-inflammatory drugs (NSAIDs) are associated with a higher probability of hepatotoxicity and kidney damage, as well as increased risk of exacerbation of heart failure, therefore, their use should be carried out with caution. The use of systemic and topical corticosteroids has little or no clinically important effect on the sunburn reaction, as stated in the study 3. Some key points to consider when treating severe sunburn pain include:
- Applying cool compresses or taking cool baths for 15-20 minutes several times daily
- Using aloe vera gel or moisturizers containing aloe vera to the affected areas 3-4 times daily
- Staying hydrated by drinking plenty of water
- Avoiding further sun exposure until healed and wearing loose, soft clothing
- Not popping blisters as they protect against infection
- Seeking medical attention if experiencing severe blistering over large areas, fever, chills, confusion, or if pain is unbearable, as these may indicate sun poisoning requiring professional treatment. It is essential to prioritize the patient's safety and monitor their condition closely when using NSAIDs, as recommended in the study 2.
