How should I use DermacinRx Lexitral PharmaPak (capsaicin and diclofenac topical)?

Follow all directions on your prescription label. Do not use this medicine in larger amounts or for longer than recommended.

Do not take by mouth. This medicine is for use only on the skin. If this medicine gets in your eyes, nose, or mouth, rinse with water.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Do not apply to open wounds or to sunburned, chapped, irritated, or infected skin. Do not cover treated skin with a bandage or expose it to heat from a hot tub, heating pad, or sauna.

The usual dose of this medicine is 40 drops applied to each affected knee 4 times per day. Apply only 10 drops at a time, placing the medicine first into your hand and then onto your knee. Repeat until all 40 drops have been applied to each affected knee.

Apply the solution only to clean, dry skin. Spread the solution over the front, back, and sides of the knee.

Wash your hands after applying this medicine. Wait at least 30 minutes before you bathe or shower.

Wait until the solution is completely dry before covering treated skin with clothing or applying any other skin products (cosmetics, sunscreen, lotions, insect repellant, or other medicated skin products).

Do not allow others to touch the area where you have applied the medicine.

Capsaicin can cause a burning sensation wherever it is applied. This sensation is usually mild and should gradually lessen over time with continued regular use of the medicine.

If the burning sensation is painful or causes significant discomfort, wash the treated skin area with soap and cool water. Get medical attention right away if you have severe burning, pain, swelling, or blistering.

If you use this medicine long-term, you may need frequent medical tests.

Call your doctor if your arthritis symptoms do not improve after 7 days of treatment, or if your symptoms get better and then worse within a few days.

Store at room temperature away from moisture and heat.

Capsaicin and diclofenac solution is flammable. Do not use near high heat or open flame. Do not smoke until the gel has completely dried on your skin.
