4. Possible side effects

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

ZACIN cream can cause a burning feeling when applied. This burning is more common when:

  • The cream is used more than 4 times a day.
  • Too much cream is applied.
  • The cream is applied just before or after a hot bath or shower.

Rarely when ZACIN cream is applied the vapour can cause brief irritation of the eyes, nose, and throat, such as runny nose, cough or sneezing, breathlessness or worsening of asthma. ZACIN may also cause irritation of the skin for example itching or stinging.
