4. Possible side effects

Like all medicines, Flector can cause side effects, although not everybody gets them.

Some less common and very rare side effects may be serious

Contact a doctor immediately and stop using the patch if you notice any of the following signs of an allergy:

  • Swelling of the lips, eyes, or tongue, shortness of breath, or asthma attack which is signs of a severe allergic reaction (may affect up to 1 in 10,000 users),
  • Skin rash, stinging, or burning sensation on the area where the patch has been applied (may affect up to 1 in 100 people).

Other side effects that may occur are usually mild, transient, and harmless (if you are worried, talk to your doctor or pharmacist).

Common side effects are (may affect up to 1 in 10):

  • Itching 

Less common side effects are (may affect up to 1 in 100):

  • Rash
  • Reddening of the skin
  • Small dark purple/dark red dots under the skin

Rare side effects are (may affect up to 1 in 1000):

  • Dry, scaly, skin
  • Swelling at the site where the patch was placed.
