Camphor and phenol are mild topical (for the skin) pain relievers. The combination of allantoin, camphor, and phenol is used to treat pain, itching, or severe lip dryness caused by chapped lips or cold sores (fever blisters). This medication will not cure herpes simplex, a virus that causes cold sores.
Concerta is a new medication for ADHD. It is a central nervous system stimulant and contains methylphenidate, the same medication ingredient found in Ritalin. It comes in 18mg, 36mg and 54mg tablets and is intended to be taken once a day.
The real difference is in the method of delivery. Concerta is designed to be effective in the body for 12 hours. Ritalin has an effective period of from 4-6 hours. The longer-lasting Concerta is intended to eliminate the need to take medication during the school day. It is important to remember that the only thing new about Concerta is the sustained delivery system.
