Warnings and precautions

Talk to your doctor or pharmacist before using Diclofenac 2.32% gel:

You are more likely to asthma attacks (so-called analgesic intolerance / analgesic asthma), local skin or mucous membrane swelling (so-called quincke oedema) or hives than other patients.

If you suffer from asthma, hay fever, swelling of the nasal membrane (so-called nasal polyps) or chronic obstructive pulmonary disease, chronic respiratory tract infections (particularly associated with hay fever-like symptoms) or hypersensitivity to other painkillers and anti-rheumatic medicines of any kind.

In these patients, Diclofenac 2.32% gel may only be used under certain precautions (emergency preparedness) and direct medical supervision. The same applies for patients who are also allergic to other substances e.g. with skin reactions, itching or hives.

When Diclofenac 2.32% gel is applied to a large area of skin and over a prolonged period, the possibility of systemic side-effects from the application of Diclofenac cannot be excluded. The gel should therefore be used with caution by patients with reduced kidney function, reduced heart function or reduced liver function as well as patients with active peptic ulcers in the stomach or duodenum.

Apply Diclofenac 2.32% gel only to intact, not diseased or injured skin. Avoid contact with eyes and mucous membranes. The gel must not be taken orally.

After applying the gel on the skin you can use a permeable (non-occlusive) bandage but allow the gel to dry on the skin for a few minutes. Do not use an airtight occlusive dressing.

If the symptoms worsen or do not improve after 3 - 5 days, consult a doctor.

The use of Diclofenac 2.32% gel should be discontinued if you develop a skin rash.

If you are exposed to direct sunlight or artificial sun there is a risk of skin reactions. You should avoid sunlight or artificial sun during treatment and for two weeks after stopping treatment.

Precautions should be taken to prevent children from touching the area to which the gel is applied.

How to apply:

Diclofenac 2.32% gel is for cutaneous use only.

The gel is applied to the affected parts of the body thinly and gently rubbed into the skin. Afterwards, the hands should be wiped with a paper towel and then washed, unless the hands are the area to be treated.

If too much gel is accidently applied, the excess gel should be wiped with a paper towel.

The paper towel should be disposed in the household waste to prevent unused product reaching the aquatic environment.

Before applying a bandage, the gel should be left to dry for a few minutes on the skin.

Duration of treatment:

The duration of use depends on the symptoms and the underlying disease. Diclofenac 2.32% gel should not be used longer than 1 week without medical advice.

If symptoms worsen or do not improve after 3 – 5 days a doctor should be consulted.

If you use more Diclofenac 2.32% gel than you should

An overdose is unlikely to happen if you use more Diclofenac 2.32% gel than you should, because the absorption into the blood stream is low when used on the skin. If the recommended dose is significantly exceeded when used on the skin, the gel should be removed and washed off with water.

If you accidentally swallow Diclofenac 2.32% gel, contact your doctor who decides on the appropriate measures.

If you forget to use Diclofenac 2.32% gel

Do not use a double dose to make up for a forgotten application.
