Scabicide ointment


I would like to ask if it is safe to wash off scabicide ointment from the neck down after 8 hours, as I found online that this medication has concerns regarding carcinogenicity and neurotoxicity.
I have been using scabicide lotion and ivermectin for two weeks, and I still haven't improved.

Scabicide ointment should not be used on children, pregnant women, or patients with a history of epilepsy.
Aside from that, its safety profile is quite high.

More Info


When it comes to the safety of washing off scab relief ointment after 8 hours, it is essential to consider both the specific medication you are using and the general principles of topical treatments.
Scab relief ointments, such as those containing ingredients like permethrin or other antiparasitic agents, are often used to treat conditions like scabies or other skin irritations. The duration for which these ointments should remain on the skin can vary based on the formulation and the specific condition being treated. Generally, these medications are designed to be absorbed by the skin to effectively combat the underlying issue, and washing them off too soon may reduce their efficacy.

In your case, if you have applied the ointment and are considering washing it off after 8 hours, it is typically safe to do so, provided that you have followed the application instructions correctly. However, if the product you are using has specific guidelines that recommend leaving it on for a longer period, it would be prudent to adhere to those instructions.
Regarding the concerns you mentioned about potential carcinogenicity and neurotoxicity, it is important to note that while some ingredients in topical medications can have adverse effects, these risks are often associated with prolonged exposure or misuse. The key is to use the medication as directed and to be aware of any side effects. If you have been using the ointment for two weeks without improvement, it may be time to consult a healthcare professional for further evaluation. They can provide guidance on whether to continue with the current treatment or consider alternative options.

In terms of safety, washing off the ointment after the recommended duration should not pose significant health risks, especially if you are not experiencing any adverse reactions. However, if you notice any unusual symptoms such as increased irritation, rash, or other concerning signs, it is advisable to seek medical attention promptly.

Lastly, if you have ongoing concerns about the safety of the ointment or its ingredients, discussing these with your healthcare provider can provide clarity. They can help you weigh the benefits of the treatment against any potential risks and suggest the best course of action for your specific situation.

In summary, while it is generally safe to wash off scab relief ointment after 8 hours, always refer to the specific instructions provided with the medication. If you have any doubts or experience any adverse effects, consulting a healthcare professional is the best course of action.
