Uses For Synalgos-DC

Dihydrocodeine, aspirin, and caffeine combination is used to relieve moderate to moderately severe pain. Dihydrocodeine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

Aspirin is used to relieve pain and reduce fever in patients. Aspirin belongs to the group of medicines known as salicylates and acts on the immune system to reduce inflammation. It is also known as an anti-inflammatory analgesic. Caffeine is a CNS stimulant that is used with pain relievers to increase their effect. It has also been used for migraine headaches.

When dihydrocodeine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription.

Before Using Synalgos-DC

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of dihydrocodeine, aspirin, and caffeine combination in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of dihydrocodeine, aspirin, and caffeine combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving dihydrocodeine, aspirin, and caffeine combination.
