Using Flector is simple, but it’s important to follow the right steps for safety and best results:
- First, wash and dry your hands.
- Clean and dry the area where you will apply the patch. Make sure there are no cuts or rashes.
- Open the package and remove one patch.
- Peel off the clear backing from the sticky side of the patch.
- Apply the sticky side directly to the sore area.
- Press it gently to make sure it sticks properly.
- Leave the patch on for up to 12 hours.
- After 12 hours, remove the used patch and apply a new one if needed.
- Always wash your hands again after applying or removing the patch.
Never use the patch on broken, irritated, or infected skin. Avoid using it near your eyes, mouth, or other sensitive areas.
Flector works by reducing inflammation, which is the cause of swelling, redness, and pain in injured muscles or joints. It does this by blocking substances in the body called prostaglandins. These substances trigger pain and swelling when an injury happens.
Because Flector is applied directly to the skin, the medicine enters the area of pain more directly than oral medicines. It targets the problem area, which makes it effective while reducing the risk of side effects that happen with oral NSAIDs like stomach upset or kidney strain.
Like all medicines, Flector can cause side effects, but not everyone gets them. Many people use the patch with no problems.
Common side effects include:
- Skin irritation (redness, itching, or a rash where the patch was applied)
- Dry or flaky skin
- Headache
These side effects are usually mild and go away on their own.
More serious but rare side effects include:
- Allergic reactions (such as swelling, hives, or trouble breathing)
- Stomach pain or ulcers (if too much diclofenac enters the body)
- Liver or kidney problems (with long-term use)
If you have any serious symptoms while using the patch, stop using it and contact your doctor right away.
There are some important safety tips and warnings to remember when using Flector:
- Do not use Flector if you are allergic to diclofenac or any NSAID.
- Do not use the patch on open wounds or damaged skin.
- People with asthma, heart disease, stomach ulcers, liver or kidney problems should speak to their doctor before using Flector.
- Avoid using the patch during the last 3 months of pregnancy, as it could harm the unborn baby.
- If you are breastfeeding, ask your doctor before using it.
- Do not use heating pads, bandages, or tight clothing over the patch, as this may increase absorption and cause side effects.
- Avoid long sun exposure on the patch area because it might make your skin more sensitive to sunlight.
Always follow the instructions and ask your doctor or pharmacist if you are unsure about anything.
Even though it is used on the skin, Flector can still interact with other medicines, especially if used for a long time or over large areas. Be careful if you are also using:
- Other NSAID medicines (like ibuprofen or naproxen)
- Blood-thinning medicines (such as warfarin)
- Blood pressure medicines
- Corticosteroids (like prednisone)
Tell your doctor about any other medicine you are taking before you start using Flector.
The general dosage rule for Flector is:
- Use one patch at a time.
- Apply it to the painful area and leave it in place for up to 12 hours.
- After removing it, you may apply a new patch to the same or a different area, but you should not use more than two patches in one day.
Never cut the patch into smaller pieces or use extra patches to speed up pain relief. More is not better and can lead to side effects.
Flector patches are usually prescription-only medicine. That means you need a doctor’s approval to get them.
Doctors prescribe Flector after checking your condition to make sure it’s safe and effective for you. Even though the medicine is applied to the skin, it is still powerful and can cause side effects if misused.
Once prescribed, you can buy it from pharmacies. There are also generic versions of diclofenac patches available, but they work the same way.
Never use someone else’s prescription, and don’t continue using Flector without follow-up from your doctor.
