Acne treatment: Minocycline and tetracycline belong to the same family of antibiotics so both share the same actions and bacterial resistance. Amoxicillin is more stable than Ampicillin and can be given 2x a day compared to 4x a day for ampicillin. As with any antibiotic for acne treatment, give Amoxicillin at least 2 - 4 weeks to effect a change in your acne.

Amoxicillin better: Amoxicillin is effective antibiotic for treatment of acne and only needs to be taken twice a day as compared to Ampicillin which needs to be taken four times a day. It still needs to be used with other therapies including benzyl peroxide and retinoids.It takes about three weeks to see positive effect and may take three months to see full effect.Long term use can cause resistance.
