Below is general information about the interactions of the known ingredients contained in the product LipoSan ULTRA Chitosan. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Chitosan can reduce the absorption of acyclovir, potentially increasing the risk for treatment failure.
Details
Clinical research in humans shows that taking chitosan along with acyclovir 200 mg reduces acyclovir absorption. Concomitant administration of chitosan 400 mg or 1000 mg reduced the acyclovir area under the curve (AUC) and peak plasma concentration by about 30% and 40%, respectively, compared with control. Concomitant administration with chitosan 1000 mg also increased time to peak concentration from 1 hour to 2 hours (92780). In vitro research suggests that the mechanism for reduced absorption is due to acyclovir entrapment in chitosan-mucus complexes, which reduces intestinal absorption (112352).

Theoretically, chitosan might increase the risk of bleeding when taken with warfarin.
Details
In a case report, a patient taking warfarin had a significantly increased international normalized ratio (INR) after starting chitosan 1200 mg daily. The INR normalized after chitosan was discontinued and vitamin K was administered. The patient once again started taking chitosan and again had a significant increase in INR. The INR stabilized again once chitosan was discontinued (15909). Researchers theorize that this interaction might occur because chitosan decreases absorption of fat-soluble vitamins, including vitamin K, which could increase the anticoagulant effect of warfarin.

General
...Orally and topically, chitosan seems to be well tolerated, short-term.
Most Common Adverse Effects:
Orally: Constipation, diarrhea, flatulence, epigastric discomfort, and nausea.
Dermatologic ...In one clinical trial, a subject with kidney failure reported itching during 12 weeks of oral chitosan treatment (1942). It is not clear if this was related to the underlying renal failure or the use of oral chitosan.
Gastrointestinal ...Orally, chitosan has been reported to cause epigastric discomfort, constipation, flatulence, diarrhea, nausea, and dryness of the throat (1942,3243,9986,11307,14314,41688,92781,100170). Excessive discharge of fat in the feces, also known as steatorrhea, has been reported with chitosan therapy (41724,41726). Theoretically, chitosan may alter the normal intestinal flora via antimicrobial activity, which could interfere with lipid digestibility and bile acid metabolism, leading to the growth of resistant pathogens (41687,41709,41725).
Musculoskeletal ...Orally, chitosan has been reported to cause swollen heels and wrists in two patients (41688).
Neurologic/CNS ...Headaches have been reported in patients taking oral chitosan (41688).
Ocular/Otic ...Topically, an eye drop containing chitosan-N-acetylcysteine has been reported to cause itching and irritation of the eyes (97710).
