How to use Diclofenac 1 % Topical Gel
Read the Medication Guide and Patient Instructions for Use provided by your pharmacist before you start using diclofenac and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
This medication is for use on the skin only. To measure the right dose, use the dosing card(s) provided with the medication. Place a dosing card on a flat surface so that you can read the print on the card. Squeeze an even line of the medication from the tube onto the dosing card, using the marks on the card to measure the prescribed dose. Gently rub the medication into the entire affected joint, usually 4 times daily or as directed by your doctor. You may use the dosing card to apply the medication. Do not apply the medication on the skin that has cuts, infections, or rashes.
If the package instructions direct you to reuse the dosing card, then after each use, hold the card with your fingertips, rinse, and dry. When you are ready to discard the dosing card, fold the card in half with the medication side inside and throw away out of the reach of children and pets. Wash your hands after using the medication unless you are using it to treat the hands. Do not shower, bathe, or wash any treated areas for at least an hour after applying the medication. Wait at least 10 minutes before covering the treated area with gloves or clothing. Do not wrap, bandage, or apply heat (such as a heating pad) to the treated area.
The dosage is based on your medical condition and response to treatment. Do not apply more than 16 grams of diclofenac per day to any single joint of the lower body (such as the knee, ankle, foot). Do not apply more than 8 grams of diclofenac per day to any single joint of the upper body (such as hand, wrist, elbow). No matter how many joints you are treating, do not use more than a total of 32 grams of diclofenac per day.

Do not get the medication in the eyes, nose, or mouth. If you do get the medication in those areas, flush with plenty of water. Contact your doctor right away if irritation persists.
Skin irritation/redness may occur at the application site. If this effect persists or worsens, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.
Tell your doctor right away if you have any serious side effects, including signs of kidney problems (such as a change in the amount of urine), symptoms of heart failure (such as swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Before using diclofenac, tell your doctor or pharmacist if you are allergic to it; or to aspirin or other NSAIDs (such as ibuprofen, naproxen, celecoxib); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: asthma, aspirin-sensitive asthma (a history of worsening breathing with runny/stuffy nose after taking aspirin or other NSAIDs), liver disease, stomach/intestine problems (such as bleeding, ulcers), heart disease (such as previous heart attack), high blood pressure, stroke, swelling (edema, fluid retention), blood disorders (such as anemia), bleeding/clotting problems, growths in the nose (nasal polyps).
Kidney problems can sometimes occur with the use of NSAID medications, including diclofenac. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen, naproxen, or ketorolac). These drugs are similar to diclofenac and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for it.
