Welcome to Healthcare Magic forum.
Simvastatin is a hypolipidemic drug which reduces LDL levels to 50% and increases HDL (beneficial for the body). The dose is started with 20 mg and then increased gradually if cholesterol
levels are not coming under recommended range.
Common side effects may include abdominal pain
, diarrhea, indigestion, and a general feeling of weakness. Rare side effects include joint pain, memory loss, and muscle cramps
. Cholestatic hepatitis
, hepatic cirrhosis, rhabdomyolysis
and myositis have been reported in patients receiving the drug chronically.
Please do not be scared of the side effects. Every drug has it own side effects which may present in some people and not everybody. You having a respiratory infection is not a side effect of simvastatin and might be present coincidentally. Coughing and wheezing could be due to the respiratory infection while nausea could be due to gastritis on consuming many drugs at a time (as you might be on antibiotics, bronchodilators, hypolipidemic drugs).
The course of simvastatin is short term. It would be discontinued once your cholesterol levels comes under recommended range. So I advise you to continue simvastatin as prescribed by your doctor.
Hope this answers your query.
Wish you a speedy recovery.
