Yes, it is safe to take Telmiwyn 80mg instead of Arbitel 80mg. Both of these brands contain the exact same active generic medicine, telmisartan, at the same strength of 80mg. This means they will work the same way in your body to help manage your blood pressure. You can transition between them safely. However, it is always a good practice to inform your doctor or pharmacist about any brand changes so your records stay updated.

Fluid retention (edema) in the face and limbs is a known side effect of amlodipine, one of the active ingredients in Arbitel-AM. Please do not stop taking your medication abruptly, as this can cause your blood pressure to spike dangerously. Instead, consult your doctor promptly. They can safely transition you to an alternative regimen, such as continuing telmisartan alone or combining it with a different class of medication, like a low-dose diuretic, which can control your blood pressure without causing swelling.
