How should I use DicloPrep-100?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the lowest effective dose for your condition.

DicloPrep-100 is usually applied up to 2 to 4 times a day. Do not use DicloPrep-100 more often or longer than directed. Your doctor will determine how long you should use this medicine.

Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using exactly as directed on the label, or as prescribed by your doctor.

Wash your hands before and after applying this medicine, unless you are using it to treat a hand condition. Clean and dry the affected area before application. Use only a small amount of medicine, apply a thin layer over the affected area and rub in gently.

If you use DicloPrep-100 for arthritis pain, make sure to use the included dosing card when applying the medicine. Do not use large amounts of diclofenac topical without medical advice.

Do not take by mouth. Topical medicine is for use only on the skin.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Do not bandage treated skin, expose it to heat, or exercise right after applying. Your skin may absorb the medicine, which could cause harmful effects.

You should wait until DicloPrep-100 has dried out where it was applied before using cosmetics, sunscreen, lotions, insect repellant, or other medicated skin products.

Do not apply DicloPrep-100 in the eyes and nose, to more than 2 body areas at the same time, to sports injuries, an open skin wound, on areas of infection, rash, burn, or peeling skin.

Call your doctor if your symptoms do not improve, or if they get worse.

Your blood may need to be tested often.

Store at room temperature away from moisture and heat. Do not freeze.

Apply the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not apply two doses at one time.

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 medicine.

What should I avoid while using DicloPrep-100?

Ask a doctor or pharmacist before using other medicines for pain, fever, swelling, or cold/flu symptoms. They may contain ingredients similar to DicloPrep-100 (such as aspirin, ibuprofen, ketoprofen, or naproxen).
