###Human: Is it necessary to get allergy testing done for perioral dermatitis? ###Assistant: Hi. You can skip Doxycycline, if you have gut problems and you cannot tolerate it. If you are suspecting that your perioral dermatitis is due to contact of any allergic material, then go for allergy testing. Otherwise it will not benefit you. I would like to know your work. Any allergy to known material and picture of your leison? You can use mild steroid preparation over it for relief. Perioral dermatitis Apply hydrocortisone 1% ointment over leisons bd for 2 weeks Take antihistamine if you have itching Rest continue with your measures Maintain hygiene of the area Wash with soap and water Avoid using dettol and other irritants Follow at 2 weeks with pics plz
