Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Not necessarily every person suffers from side effects of the drug, it is the individual body’s response to drug elements varying widely. So your husband can get some more or less side effects or even may not get any of them, which can be revealed after its consumption. Common side effects include: abdominal discomfort, dry mouth, nausea and vomiting, chest discomfort, sore throat, stuffy nose, nervousness, increased thirst or urination, chills, flushing, headache, tiredness, heartbeat alterations, and weight alterations. Less common are concentration problems, loss of sleep, red eyes, joint swelling, muscle cramps, diarrhea, tingling peripheries, sadness feeling, peripheral issues as pins and needles, and skin blisters. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Purva Patel
