Brand Name: Uracil
Uracil is used for:
Treating inflammatory lesions caused by rosacea.
Uracil is a tetracycline. Tetracyclines are often used to treat infections; however, Uracil will not treat infection. It works by reducing skin inflammation caused by rosacea.
Do NOT use Uracil if:
- you are allergic to any ingredient in Uracil or to another tetracycline (eg, minocycline)
- you are taking acitretin, isotretinoin, methoxyflurane, or a penicillin antibiotic (eg, amoxicillin)
- you have recently received or will be receiving a live oral typhoid vaccine
Contact your doctor or health care provider right away if any of these apply to you.
Before using Uracil:
Some medical conditions may interact with Uracil. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

- if you have diarrhea, a history of kidney or liver problems, the blood disease porphyria, lupus, or recurring fungal infections in the mouth or vagina

- Barbiturates (eg, phenobarbital), carbamazepine, hydantoins (eg, phenytoin), iron, proton pump inhibitors (eg, omeprazole), or urinary alkalinizers (eg, sodium bicarbonate) because they may decrease Uracil's effectiveness
- Live oral typhoid vaccine, hormonal birth control (eg, birth control pills), or penicillins (eg, amoxicillin) because their effectiveness may be decreased by Uracil
