Cautions with other medicines
It's very unlikely that other medicines will affect the way betamethasone skin treatments work.
If you're also using any other skin treatment, make sure you wait about 30 minutes between using betamethasone and using the other skin treatment.
Tell a pharmacist or doctor if you're taking:
- medicines used to treat HIV, such as ritonavir or cobicistat
- medicines used to treat fungal infections, such as itraconazole
- other medicines that contain steroids, such as eczema creams, asthma inhalers, steroid tablets, injections, nasal spray, and eye or nose drops
There's not enough information to say that complementary medicines and herbal remedies are safe to take with betamethasone. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
