While not very common, muscle or joint pain can be a side effect of Temsan H 40 (telmisartan/hydrochlorothiazide). Since orthopedic causes have been ruled out, it is possible the medication is contributing to your shoulder pain. Please consult your prescribing doctor before making any changes; do not stop taking your medication abruptly. Your doctor can evaluate if switching to a different blood pressure medication resolves the discomfort. Additionally, because shoulder pain can sometimes be referred pain, your doctor can perform a quick overall assessment to ensure your cardiovascular health is fully monitored.
