Frequently Asked Questions
How long can I use Mometasone safely?
For skin conditions, usually 2-4 weeks maximum. For nasal spray, can be used longer term but requires regular review. Prolonged use increases risk of side effects.
Can I use Mometasone on my face?
Only if specifically prescribed by your GP. Facial skin is thinner and more prone to side effects from potent steroids.
Why shouldn't I use it on infected skin?
Steroids can suppress local immune responses and may worsen infections. If infection is suspected, antimicrobial treatment is needed first.
Is it normal for my skin to sting when I first apply it?
Mild stinging is common initially, especially on inflamed skin. If severe burning persists, stop use and contact your GP.
