Interaction Details
Acetaminophen, Dextromethorphan, Doxylamine, Pseudoephedrine is classified as belonging to the following category: Acetaminophen (Tylenol, Others)
Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis. Some research suggests that the sulfate portion of glucosamine sulfate might contribute to its effect in osteoarthritis. Since acetaminophen metabolism requires sulfur and reduces serum sulfate concentrations, acetaminophen could theoretically interfere with the action of glucosamine sulfate. Conversely, the administration of sulfate could theoretically decrease the effectiveness of acetaminophen in sulfate-deficient people by increasing its clearance.

Glucosamine Overview
Glucosamine is a natural compound found in the body, particularly in the fluid that surrounds joints. It is often used as a dietary supplement to help with joint health, particularly for conditions such as osteoarthritis. Glucosamine is believed to work by helping to reduce inflammation, promoting the repair of damaged cartilage, and slowing down the loss of cartilage.
There are several different forms of glucosamine supplements, including glucosamine sulfate, glucosamine hydrochloride, and N-acetyl-glucosamine. Glucosamine sulfate is the most commonly used form in supplements. It is important to note that glucosamine sulfate is derived from shellfish (specifically the exoskeletons of shrimp, lobster, and crabs) and can be problematic for people with shellfish allergies.
