Interactions between your drugs
procaine penicillin omadacycline
Applies to: Bicillin C-R 900/300 (penicillin g benzathine / procaine penicillin), omadacycline
GENERALLY AVOID: Tetracyclines may reduce the effect of penicillins by inhibiting cellular protein synthesis which is necessary for cell wall synthesis inhibition by penicillins. Antagonism is more likely when low doses of either agent are administered. Therapeutic failure may result.
MANAGEMENT: This combination should be avoided if possible.

Drug and food interactions
omadacycline food
Applies to: omadacycline
ADJUST DOSING INTERVAL: Administration with food, particularly dairy products, may reduce the absorption of omadacycline. The calcium content of these foods may form nonabsorbable chelates with omadacycline.
MANAGEMENT: Omadacycline should be administered at least 2 hours before (4 hours for dairy products) or 4 hours after meals.
