The side effects of Immutol, a beta-glucan, depend on the route of administration, according to WebMD. The side effects of oral beta-glucans are not yet known, but when taken by injection, the side effects can include fever, chills, pain at the injection site, joint pain, nausea, headache, dizziness and rashes.
Immutol is a beta-glucan, states Biotech Pharmacon. Beta-glucans are likely safe when taken in quantities naturally found in food, and they are possibly safe when taken by mouth, but people should limit the oral dosage to 15 grams per day for longer than eight weeks, states WebMD. People with AIDS or HIV may develop thick patches of skin on the palms and the soles of the feet as a side effect of beta-glucans. These patches can appear during the first two weeks of treatment, then disappear several weeks after treatment is discontinued. Side effects in pregnant and breast-feeding women are unknown, so these groups are advised to avoid using beta-glucans.
Beta-glucans such as Immutol are sugars from the cell walls of bacteria, fungi, algae, lichens, yeast and certain plants, explains WebMD. They are sometimes used to treat high cholesterol, cancer, diabetes or HIV/AIDS, and they boost weakened immune systems. Beta-glucans are also used topically to treat certain skin conditions.
