Hi,
I was given them once, after having enteric coated ones. Didn't think anything of it, but was having trouble swallowing them. I got a new prescription early, and just enquired with the pharmacist if they were elongated ones or the rounds ones as I was experiencing difficulty swallowing the round ones. She said that I wasn't prescribed the round ones, but was the elongated enteric coated ones, and I have never received them again. It may be worth asking your pharmacist or GP what has been prescribed.
Hope this helps.
Take care
Candy
