How should I use this medication?
Shampoo: Approximately one ounce (about 30 mL) or less of shampoo should be applied to wet hair and scalp once daily. Work into a lather and leave on the scalp for 5 minutes before rinsing twice with clear water.
Otic (ear) solution: Tilt the head so the affected ear is facing up. Gently pull the earlobe backward and upward to open the ear canal. Apply 5 drops of solution into the ear and keep head tilted for one minute to let the drops run into the ear canal. This should be repeated twice daily. Improvement should occur within 7 days. Contact your physician if your condition does not begin to improve within 7 days.
Do not use the ear solution if the eardrum is perforated.
Oil: After wetting or dampening the affected area, apply a thin film of oil 2 to 3 times daily as prescribed by your doctor. Massage the oil into the skin gently.
The affected area should not be covered with dressings that do not allow the skin to breathe, including diapers when applied to small children. This medication should not be applied to the face, groin, or underarm areas. Applying the oil to these areas may cause enough medication to be absorbed into the body to cause side effects.
Use the oil for the minimum length of time necessary to heal the skin condition.
Avoid getting this medication into your eyes. If contact does occur, flush your eyes immediately with plenty of water.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Absorption: When fluocinolone is used over extensive areas for prolonged periods and under dressings that don't breathe, it is possible that enough medication will absorb into the bloodstream to give rise to unwanted side effects. Therefore, it is advisable to use fluocinolone for brief periods only and to stop using it as soon as the problem clears.
Adverse effects: Although adverse effects associated with the use of this medication are uncommon and not to be expected from ordinary use, sensitization, irritation, and failure of therapeutic response have been noticed in rare instances. If you don't notice an improvement in your skin condition after using this medication for one week, contact your doctor.
Eyes: Use this medication with caution on lesions close to the eye. Take care to ensure that it does not enter the eye, as glaucoma may result. Cataracts have been reported following internal use of corticosteroids.
Infection: Topical corticosteroids may increase the risk of developing a skin infection. Contact your doctor if you notice any increased redness, swelling, heat or pain around the area where the medication is applied as these are possible signs of infection.
Peanut allergy: This medication contains refined peanut oil. People with peanut allergy should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Thinning of skin: Using topical corticosteroid medications for a long period of time can cause skin to thin or soften or cause stretch marks. Your doctor may recommend you stop using this medication once in a while or to apply to one area of the body at a time. Suddenly stopping corticosteroid medication may cause psoriasis to return.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication may pass into breast milk. If you are a breast-feeding mother and are taking fluocinolone acetonide, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using fluocinolone acetonide topical oil have not been established for children under 1 year old. The safety and effectiveness of fluocinolone acetonide ear drops has not been established in children under 12 years old.
