Patients taking<unk>  may experience following side effects: * Headache * Low level of gastric side effects * Nausea can be a side effect, but the patient is generally already experiencing nausea due to the vertigo so it goes largely unnoticed. * Patients taking<unk>  may experience several hypersensitivity and allergic reactions. In the November 2006 issue of "Drug Safety," Dr. Sabine Jeck-Thole and Dr. Wolfgang Wagner reported that<unk>  may cause several allergic and skin-related side effects. These include rash in several areas of the body; itching and hives; and swelling of the face, tongue and mouth. Other hypersensitivity reactions reported include tingling, numbness, burning sensations, shortness of breath and laboured breathing. The study authors suggest that hypersensitivity reactions may be a direct result of<unk> 's role in increasing histamine levels throughout the body. Hypersensitivity reactions quickly subside after<unk>  has been discontinued. Digestive<unk>  may also cause several digestive-related side effects. The package insert for Serc, a trade name for<unk> , states that patients may experience several gastrointestinal side effects. These may include nausea, upset stomach, vomiting, diarrhea, dry mouth and stomach cramping. These symptoms are usually not serious and subside between doses. Patients experiencing chronic digestive problems may lower their dose to the minimum effective range and by taking<unk>  with meals. Additional digestive problems may require that patients consult their physician in order to find a possible suitable alternative. Others People taking<unk>  may experience several other side effects ranging from mild to serious. The package insert for Serc states that patients may experience nervous-system side effects, including headache. Some nervous system events may also partly be attributable to the underlying condition rather than the medication used to treat it. The study by Jeck-Thole and Wagner also reports that patients may experience headache and liver problems, including increased liver enzymes and bile-flow disturbances. Any side effects that persist or outweigh the relief of symptoms of the original condition may warrant that the patient consult their physician to adjust or change the medication.
