Important information about some of the ingredients of Synalar gel

Some of the ingredients in your gel may cause a reaction, such as: Methyl and propyl parahydroxybenzoate [E218 and E216] – may cause local skin reactions (possibly delayed). Propylene glycol [E1520] – may cause skin irritation.


Always use Synalar gel exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Screw the nozzle onto the end of the tube. This will allow you to apply your gel directly on to the affected part of the skin at the roots of the hair.

Unless your doctor tells you differently, a small amount of gel should be massaged into the affected area every night and every morning at roughly the same time.

Once the condition is under control you can reduce the treatment and apply the gel once or twice a week. Use the gel for as long as directed by your doctor (normally 5 days on the face and on children).

If you forget to use Synalar gel

If you forget to apply the gel at the correct time, do so as soon as you remember.

If accidentally swallowed

If you accidentally swallow the gel, contact your nearest doctor or hospital.

If you have any further questions on the use of this medicine ask your doctor or pharmacist.


Like all medicines Synalar gel can cause side effects, although not everybody gets them. The following side effects have been reported but how often they occur is unknown:

  • an allergic (itchy) reaction to the gel
  • irritation where the gel has been applied
  • a worsening of acne, rosacea and dermatitis around the mouth (see section 2)
  • patches of pale skin (depigmentation)
  • localised increased hair growth
  • if too much gel is used for too long, you may develop stretch marks, thinning of the skin or visible small veins. In addition some of the steroid rubbed in to the skin may enter the blood stream. Effects such as roundness of the face, muscle wasting and fluid retention, as sometimes seen when steroids are given as tablets, may occur. The risk of these possible effects is higher in children. If this happens, your doctor may decide to stop treatment.

Do not be alarmed by this list of possible side effects. You may not have any of them.
