Synalar gel contains fluocinolone acetonide which is a corticosteroid (also referred to as a steroid) and reduces inflammation.
It is used to treat certain inflammatory conditions such as seborrhea and psoriasis of the scalp and other hairy parts of the body. It may also be used to treat certain inflammatory conditions of the skin on other parts of the body.
Corticosteroid creams, ointments and other topical preparations come in four different potencies or strengths. These are known as mild, moderately potent, potent or very potent. Healthcare professionals will usually refer to topical corticosteroid potency rather than strength. A potent or strong corticosteroid has a much stronger effect than a mild corticosteroid when using the same amount. The percentage of active ingredient that is sometimes included on product packaging does not indicate potency. Synalar gel is classed as a strong corticosteroid.
Your healthcare professional will prescribe or advise a steroid of the appropriate potency for your condition.
Make sure your doctor knows if any of the above affects you.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
If you go into hospital, let the medical staff know that you are using Synalar gel.
If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Synalar gel should not affect your ability to drive or use machinery.
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.
Use the nozzle of the tube 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 apply the gel at the correct time, do so as soon as you remember.
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.
