Opened a new box and the blister has two different looking tablets alternating. One is round and white, the other is oblong and slightly yellow. The box says one product. Is this a packaging thing or should I be worried?
Combination products exist where two actives are in one tablet, but they are in the same tablet, not alternating. Alternating shapes in one blister is unusual and worth a photo to the manufacturer’s medical information line, who answer this sort of thing for free.
Also worth checking whether the blister is the one that came in the box, or a mixed pack somebody made up. Second-hand boxes are a thing.
Please come back and tell us what they said, these threads are more useful when they close.
It was sealed. Emailing the manufacturer.
