Application

When applying resorcinol, patients should avoid getting it in their eyes or mouth. If the medication does get into any of these areas, rinse with cold water immediately and call your healthcare professional for advice.

Other drugs:

It is unlikely any other prescribed drugs will affect topically applied resorcinol, but you should always consult your doctor before taking any new drugs, both prescribed and over-the-counter, including herb, vitamin and mineral supplements.

Overdose:

When applying resorcinol it is important that you stick to the dosage levels supplied by your healthcare professional. DO NOT apply the cream more often than directed in the hope your condition will clear up sooner. Applying too much cream may result in resorcinol poisoning, which can be fatal. If you start to feel unwell during treatment contact your doctor immediately.

Pediatrics:

Children are more at risk of resorcinol poisoning so care should be taken to reduce dosage levels and that the medicine is only applied to affected area. Resorcinol should not be applied to open wounds or broken skin, since this increases the risk of resorcinol poisoning and may cause the blood disorder methemoglobinemia, which in severe cases can be fatal.

Allergies:

Patients should tell their doctor if they have previously had an allergic reaction to resorcinol or any other medicine. You should also notify your doctor of any other type of allergy you have such as food, animal and dye allergies.

Pregnancy:

There is currently insufficient data to provide evidence about the need to monitor the fetus during pregnancy. Doctors are therefore advised to carry out case-specific risk assessments before prescribing resorcinol to pregnant patients.

Nursing:

No tests have been carried out to determine if resorcinol is passed into breast milk or if it harms a nursing baby. It is therefore advised that the resorcinol not be prescribed until the mother has finished nursing.

Storage

Resorcinol should be kept out of reach of children and stored at room temperature 20°C to 25°C (68°F to 77°F) in a secure container or medicine cabinet which provides protection from direct sunlight, heat and moisture. Do not freeze, if the medicine becomes frozen it should be disposed of immediately.

Note: Medicine which is no longer required or past its expiry date should be disposed of properly.

Summary

Resorcinol (topical) is a prescription medicine used to treat various skin disorders including; acne, seborrheic dermatitis, eczema, and psoriasis. It can also be used to treat corns, calluses, and warts. Resorcinol works by breaking down hard, scaly or rough skin from the outer layer of the dermis to improve the appearance of mild acne scars and uneven skin tone.

Supplied as either an ointment or lotion, resorcinol is applied to affected areas and massaged into the skin. Care needs to be taken to ensure that none of the medicine gets into the eyes or mouth. Resorcinol should NOT be applied to broken skin or large areas of unaffected skin. After application patients should wash their hands to remove any residue.

Resorcinol can be applied by the patient but care should be taken to follow dosage guidelines carefully. Overuse can lead to resorcinol entering the bloodstream through the skin, which increases the risk of resorcinol poisoning and the blood disorder methemoglobinemia. Patients who begin to feel ill during a course of treatment should contact their healthcare professional immediately.

So long as the drug is applied correctly, there are very few side effects associated with using resorcinol. However, it is important that the prescribing doctor carries out a full inspection of the patient's medical records before prescription. A small minority of patients may show an allergic reaction to resorcinol, in this case, the patient's medical history should indicate whether a reaction is likely to occur.

When using resorcinol it is important that patients make their doctor aware of any other facial creams or medication they may be used to treat the problem. Combining resorcinol with other medicated cosmetics or peeling agents which contain benzoyl peroxide, salicylic acid, sulfur, or vitamin A acids, may result in irritated or dry skin.
