Pityriasis rosea

Pityriasis rosea starts as a large circular rash usually on the chest, abdomen or back. The initial rash is followed by smaller patches. The cause of pityriasis rosea is unknown.

The rash is common in older children and young adults. The patches are not painful but may be itchy.

The rashes will usually go away on their own within ten weeks. You cannot pass the rash to other people.

• A large circular rash called the herald or mother patch.
• Headache and fatigue before or when the herald patch appears.
• Smaller rashes, called daughter patches, form in the pattern of a Christmas tree.

The cause is unknown, but it is suspected that it has something to do with some herpes virus infections.

Pityriasis rosea can occur in anyone, but there is an increased risk when you are aged between 10-35 years.

You should visit your doctor if:

• The rash does not go away after a few weeks but continues to spread.
• Itching from the rashes becomes worse instead of reducing.

There’s no way to prevent pityriasis rosea.

Self-care tips:

• You can use anti-itch creams to relieve the itchy rash.
• Over-the-counter pills like piriton can help with itchy rash too. Piriton may make you sleepy, do not drive or operate a machine when using it.
• Bathing with lukewarm water and applying a mild moisturiser on the skin can relieve inflammation and improve the appearance of the rash.

Treatment options:

• Your healthcare provider may recommend medications that relieve rash. This can include steroids or antiviral drugs if self-care does not help and the condition does not clear on its own.

Pityriasis rosea will usually go away on its own without leaving any scars. It is not contagious and will usually not return once it goes away.
