NOTE FOR DVM DISCUSSION: Even though your dog might have megaesophagus, an NSAID (Previcox, etc.) can be used as part of pain management protocol, even if it’s used every other day. Adequan injections can also both help without minimizing joint destruction, but, can help w/ the discomfort. Veterinary brand glucosamine/chondroitin/MSM/perna canniculus nutraceuticals frequently help without the pain. Amitriptylline, an anti-anxiety medication, can affect the pain sensory nerves and help minimize the pain. Amantadine, an anti-flu medication, decreases the wind-up pain in patients with chronic pain (i.e. when you’ve been in pain for a long time, the pain “winds-up,” or gets magnified). Gabapentin and tramadol are not the only medications that they can have. Most of these meds can be used together, and, by using a cocktail, you can use less of each one.
