My 3,4 dap is due to arrive next week, on the sheet
I was given it states you assume the risk of getting a
Abnormal heart rythym by taking 3,4 dap..
Now the only issue I have is palpitations already and I'm not even on the dap yet. Did anyone out there have any issues With their heart and 3,4 dap?

Hate to reply to my own post, but seems no one had any answers. We are all differentand people react differently to meds..

I finally started the 3,4 Dap and have noticed a slight increase in my palpitations, but nothing like the mestinon did to me.
I also noted more anxiety and have had to take 7 ativans so far as to not go into a panic attack.

Also the 3,4 Dap to me is no wonder drug like many here claim BUT I am on a small dose yet
they started me as follows

week 1 5 mg a day
week 2 5 mg twice a day
week 3 5 mg three times a day
week 4 10 mg in the morning and 5 mg at noon and 5 mg at 6 pm
week 5 was supposed to be 10 mg in the morning 10 mg at noon 5 mg evening but i was getting no effect at all. I called and was put on
10 mg ( full pill) every 6 hours during waking time
so I take a 10 mg at 6 am 10 mg at noon and 10 mg at 6pm

So far the only results i see are a little less dry mouth and that is about it as far as the positives, i get no "tingle" an hour after a pill or anything.
I am still very weak and see no strength increase anywhere at all (legs,fingers,hands,arms,etc)

I was told if there is no result by Monday to call them and they will double my dosage to 20mg 3 times per day..

Sorry, I didn't see your post before, possibly because I was on a lot of drugs at the time. The dap has no effect on my heart.
When I first started taking it the ten mg made me a little agitated as if I had drank too much coffee, but it did make me stronger. I currently take sixty mg a day divided as follows:

6am. 10mg
8am. 5mg
10am 5mg
12pm 10mg
2pm. 5mg
4pm. 5mg
6pm. 10mg
8pm. 5 mg
10pm. 5mg
Hope you see some results soon.

Is the drug helping you?

It definitely helps. I can certainly tell if it is late or I forget a dose.
