In pregnancy, treatment options do get more limited due to safety issues.
Topical treatments are generally safer and include:
- Benzoyl peroxide
- Clindamycin
- Erythromycin
- Glycolic acid
- Azelaic acid
- Salicylic acid (only in low concentrations and to be used with caution)
If you have tried those without much response, the following oral antibiotics can be considered:
- Erythromycin
- Penicillins
Other treatments will be machine driven therapies such as different lasers targeted at treating acne.
Do speak with your doctor so that a safe and effective plan can be tailored for you.
Hope this helps.
All the best!
