Overview
Diclofenac is a prescription nonsteroidal anti-inflammatory drug (NSAID) that comes in multiple topical and oral forms. It works by stopping the body’s production of a substance that causes pain and inflammation.
Doctors prescribe diclofenac to treat mild to moderate pain caused by certain types of arthritis, menstrual cramps, and migraine.
Diclofenac is a generic medication. But different forms come as different brand-name medications like Zipsor, Cataflam, Cambia, and Voltaren.

How long does it take diclofenac to leave the body?
How long it takes diclofenac to leave the body may vary depending on the form of the drug you’re taking or using.
To know how long a drug will stay in your system, doctors look at something called the drug’s “half-life”. This is the amount of time it takes for half of the drug to leave your system. It usually takes about 4 to 5 half-lives to remove a drug entirely from your body.
Oral diclofenac generally has a short half-life of about 2 hours. This means it should take about 8 to 10 hours for it to leave your system.
It’s more complicated to determine how long a topical medication stays in your system. Some 2020 research suggests that topical diclofenac can penetrate into the skin after repeated applications and can remain detectable in your system 12 hours after dosing, so it may have longer pain-relieving effects than its half-life would suggest.
The time it takes for diclofenac to leave your system may also depend on other medications you take and your metabolism, age, kidney function, and overall health.

The duration of pain relief can vary depending on the form of diclofenac you’re taking. For example, extended-release tablets release the drug into the body slowly over time. How long the effects last may also vary based on how your body responds to the medication.
It’s important to follow your dosage and dosing schedule as your doctor prescribes. This maintains the effectiveness of diclofenac in managing pain and helps avoid side effects.
Side effects from diclofenac can also vary in duration and intensity. This depends on your personal health history and specific side effects you may experience.
Common side effects like upset stomach or headache may last for a few hours to a couple of days. However, more serious side effects, such as stomach ulcers, kidney issues, or allergic reactions, may persist longer and require immediate medical attention.
It’s important to monitor any side effects you may experience while taking diclofenac. Let your doctor know about them right away. If side effects worsen or don’t go away over time, you should contact your doctor.
How long does diclofenac take to work?
How long diclofenac takes to work depends on its form and how it’s absorbed. Oral diclofenac potassium, for example, is absorbed within 10 minutes, with peak blood concentrations occurring after 1 hour. This means it likely gets to work very soon after dosing — possibly as soon as 20 to 30 minutes after taking it.
Topical forms, on the other hand, can take up to 2 days to work. If you’re using them long-term for a chronic condition like arthritis, you might need to use the gel for up to 1 week to see results.
How long after diclofenac can I take ibuprofen?
You should typically avoid taking other NSAIDs like ibuprofen while you’re taking diclofenac. Using multiple NSAIDs together won’t provide any extra pain relief. It can actually worsen their performance and potentially cause harmful side effects.
Side effects may be mild, like heartburn, but they can also be serious, like stomach ulcers, stomach bleeding, or kidney damage.
When you’re taking diclofenac, you should keep an eye out for other NSAIDs that may be present in over-the-counter (OTC) pain relief products you may be taking. Other NSAIDs may include:
- ibuprofen (Advil, Motrin)
- naproxen (Aleve, Naprosyn)
- aspirin
These may be ingredients in OTC cold medications, antacids, menstrual cramp relief products, and headache relief products. Due to the risk of side effects, it’s important to consult with your doctor or pharmacist before combining these medications to ensure their safety for your situation.
Summary
The time it takes for diclofenac to leave your system may vary depending on what form of the drug you’re taking or using. It will take around 5 to 10 hours for your body to remove most of the diclofenac from your body after a single dose. The pain-relieving effects of diclofenac typically wear off after 15 hours for the oral forms and 1 to 2 days for topical forms.
It’s important to avoid taking other NSAIDs while you’re taking diclofenac. Combining this drug with other NSAIDs like ibuprofen could increase your risk of side effects.
It’s important to only take diclofenac at the dosage and frequency your doctor prescribes. If you feel that diclofenac isn’t working or are concerned about how long diclofenac stays in your system, talk with your doctor for information and guidance.
