Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Before taking this medicine
You should not use Mytrex if you are allergic to nystatin or triamcinolone.
Tell your doctor if you have diabetes. Steroid medicines may increase the glucose (sugar) levels in your blood or urine. You may also need to adjust the dose of your diabetes medications.
FDA pregnancy category C. It is not known whether Mytrex will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.
It is not known whether nystatin and triamcinolone topical passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Do not use this medicine on a child without a doctor's advice. Children can absorb larger amounts of this medication through the skin and may be more likely to have side effects.
How should I use Mytrex?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not take by mouth. This medicine is for use only on the skin.
Wash your hands before and after using Mytrex, unless you are using the medicine to treat the skin on your hands.
Apply a thin layer of nystatin and triamcinolone to your skin and rub in gently. Do not apply the medicine over a large area of skin.
Do not cover the treated skin area. Covering the skin that is treated with topical steroid medicine can increase the amount of medicine your skin absorbs, which may lead to unwanted side effects. If you apply this medicine to your groin area, wear loose-fitting clothes.
When treating the diaper area of a baby, do not use plastic pants or tight-fitting diapers.
Use Mytrex regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Call your doctor if your skin condition does not improve after 25 days of treatment, or if it gets worse while using this medicine.
If you use this medicine long-term, you may need frequent medical tests at your doctor's office.
Store at room temperature away from moisture and heat. Do not freeze. Keep the tube tightly closed when not in use.
What happens if I miss a dose?
Apply the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.

However, long term use of high steroid doses can lead to symptoms such as thinning skin, easy bruising, changes in the shape or location of body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.
