Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: If you have had a reaction to acetylsalicylic acid (ASA) or other NSAIDs (e.g., ibuprofen, ketorolac, naproxen) that included a runny nose, itchy skin rash, nasal polyps, or shortness of breath and wheezing, you should not use this medication. If you experience symptoms of a severe allergic reaction (e.g., hives; difficulty breathing; wheezing; swelling of the face, tongue, or throat), get immediate medical attention.
In rare cases, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS syndrome) may occur. This reaction involves symptoms including fever, swollen glands, yellowing of the skin or eyes, flu-like symptoms with skin rash or blistering, or other organ involvement. Get immediate medical attention if you have symptoms of a severe allergic reaction.
Asthma: People who have or have had asthma should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you have any unusual difficulty breathing while using this medication, contact your doctor immediately.
Drowsiness/reduced alertness: Some people have reported headache, dizziness, lightheadedness, and confusion while using this medication. Avoid operating motor vehicles and doing other potentially hazardous activities until you have determined how this medication affects you.
Heart Problems: When taken by mouth, diclofenac can cause fluid retention and edema (swelling). This can lead to high blood pressure or worsening of heart failure. If you have a history of heart disease or have risk factors for heart disease (e.g., high blood pressure, high cholesterol, diabetes, smoking, kidney disease), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Hepatic porphyria: This medication may trigger an attack in people with a liver condition known as hepatic porphyria. People with this condition should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infection: This medication may mask some of the signs of infection, such as fever.
Kidney function: People with reduced kidney function may need lower doses and more frequent medical checkups while using this medication.
Liver function: This medication may cause liver problems. If you have a liver condition, you may need more frequent checkups with your doctor. If you develop signs of a liver problem (such as yellow skin or eyes, dark urine, pale stools, abdominal pain, or itchy skin), stop taking the medication and see your doctor as soon as possible.
Stomach: Stomach ulcers and bleeding from the stomach have been known to occur when diclofenac is taken by mouth. These complications can occur at any time and are sometimes severe enough to require immediate medical attention. Although these reactions have not been known to occur with diclofenac topical solution, you should seek medical attention immediately if you notice any signs of bleeding (such as dark, tarry stools, blood in the stools, or vomiting material that looks like coffee grounds).
Sun sensitivity: This medication may make your skin more sensitive to the sun. While you are using this medication, avoid excessive sun exposure, including tanning beds and sun lamps. If you experience sunburn with itching, swelling, and blistering, stop using this medication and contact your doctor.
Vision: Other medications in the same family as diclofenac may cause vision changes such as blurred or decreased vision. If you notice vision changes, stop using the medication and check with your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If diclofenac is taken during the earlier stages of pregnancy, there is also an increased risk of miscarriage. Use of diclofenac at 20 weeks or later in pregnancy may increase the risk of kidney damage and complications due to low amniotic fluid in the developing baby. When diclofenac is taken during the last 3 months of pregnancy, there is an increased risk of the child developing heart problems and the mother having a longer labour to deliver the baby. If you become pregnant while taking this medication, contact your doctor as soon as possible. If you become pregnant while using this medication, stop using it immediately and call your doctor.
Breast-feeding: It is not known if diclofenac topical solution passes into breast milk. This medication is not recommended for breast-feeding women.
Children: Diclofenac topical solution should not be used by children.
Seniors: Seniors may have a higher risk of side effects with this medication. Seniors may need lower doses of this medication and more frequent medical checkups.
