I'm Dr. Jo and I'm here to help you with your question about Duffy. I'm so sorry he's done this and has you worried, but glad you're looking for the information you need.
You may join the conversation at any time by typing in what you want to say then clicking REPLY. That way we can chat back and forth until you're satisfied with the information I've provided and are happy to give me a positive rating.
I am accessing my database on the toxic dose of phentermine and will have the information in hand in a few moments.
In the meantime, please tell me the following...
1. How long ago did this happen?
2. How much does Duffy weigh?
3. Does Duffy take any other medications?
4. Is Duffy otherwise healthy?
Thank you.

Thank you for the extra information.
While it's soon enough after ingestion to induce vomiting, I don't think the risks of doing so outweigh the benefits at this point.
Typically severe signs of phentermine toxicity start at about 5 mg/kg. That means a dog Duffy's size (20 pounds = 9kg) isn't expected to have severe problems until he's had more than 45mg.
When a 20 pound dog receives more than 45mg of phentermine, Central Nervous System signs tend to predominate: agitation, tremors (unlikely to see seizures at this dose).
Phentermine has a pretty rapid onset of action, typically within 2 hours. So if after 3 hours Duffy isn't showing any symptoms, you may not see much of anything to worry about.
If you'd rather not take any chances, I'd advise taking him to an ER right away so they can induce vomiting, but - as I said - that's a judgement call and not without risk.
Also, if there's a chance he ate more than one 30mg tablet, I'd advise seeking emergency care.
I hope this offers you some peace of mind.

Just checking in to ask how Duffy is doing now. Because of the way this medication works, if he hasn't had any problems yet, he isn't likely to now.
I hope he's doing all right. Please take a moment to send an update when you can.
Thank you.
