Capsule, both on 123 and 131. If it is a
capsule with plastic-like coating, the best way I have found to swallow it is to fill your mouth with water, take the capsule and tilt your head down TOWARD your chin...the capsule will float to the back of your throat. Swallow in that position, the capsule should go down first. If you have pills, the opposite is true, tilt your head back, the pills will sink to the back of your throat then swallow. Good luck.
