Betaserc Adverse Reactions

Like all medicines, Betaserc may have side effects. If the patient notices any side effects not mentioned in this monograph, or if any of the side effects get serious, they must be advised to inform the doctor or pharmacist.
The following undesirable effects have been experienced with the following indicated frequencies in Betaserc-treated patients in placebo-controlled clinical trials: common (between 1 and 10 cases in 100 treated patients).
Gastrointestinal disorders: Common: nausea and indigestion (dyspepsia).
Nervous system disorders: Common: headache.
In addition to those events reported during clinical trials, the following undesirable effects have been reported spontaneously during postmarketing use and in scientific literature. A frequency cannot be estimated from the available data and is therefore classified as "not known".
Immune system disorders: Allergic (hypersensitivity) reactions, including a serious allergic reaction (anaphylaxis) which can cause: a red or lumpy skin rash or inflamed itchy skin; swelling of face, lips, tongue or neck; a drop in blood pressure; loss of consciousness; difficulty breathing.
Gastrointestinal disorders: Mild gastric complaints (e.g., vomiting, gastrointestinal pain, abdominal distension and bloating). These can normally be dealt with by taking the dose during meals or by lowering the dose.
Skin and subcutaneous tissue disorders: Allergic reactions of the skin or tissues under the skin, in particular a sudden onset of face, neck or limb swelling (angioneurotic oedema), hives (urticaria), rash and itchiness (pruritus).
If any of the side effects get serious, or if the patient notices any side effects not listed in this monograph, they must be advised to inform the doctor or pharmacist.
