Propranolol dosage, different anxiety control?

[intense]

I find if I take my 40mg dose of Propranolol I am fine. But a particularly stressful event came along and I checked the box. It says "as needed" so I thought I'd take two instead of one tablet, so 80mg. This is only about half what people often take for other Propranolol uses so I assumed it would be OK.

I found my anxiety ramped up really high, much higher than I would expect it to have been on 40mg. It was almost like I hadn't taken it at all.

Has anybody else noticed this? I will stick to my 40mg, but if anyone knows why this might be or has experienced it too?

Hi INtense

I used to take propranalol I was on 40 mg three times a day. On the odd occassion I did take 80 at one time if I was particularly stressed. and it did the trick. Is it possible that sub consciously you were more worried about taking the higher dose and this is what kicked off the anxiety?

Hiya Pooh.

I wondered if it was psychological but I felt awfully shaky as well, like my hands. Propranolol can contract the airway a little bit so maybe I subconsciously felt like I couldn't breathe at that dosage. I will probably stick to 40 though because that seems to do nicely - even in high stress presentations!!!!!

When you take prop at a much higher dose than you are used to it can make you feel awfull i went from 10mg to 60mg overnight once and it was a nigthmare my main prob was feeling violently ill for two-four days till I got used to it

Test your maths below...

1 x 40 mg = 40 mg.
2 x 40 mg = 40 mg.

(it does not = 80 mg, just lots more 40 mg so it takes longer to wear off.

Why?
Example 1: - Alcohol

Imagine we are talking about alcohol. If you pour a shot of 40% vodka into a glass then tip half out, what is the % of the remaining vodka?
The answer would be 40%.

Example 2: - Paint Mixing

Imagine you have 2 tins of blue paint (just like you have 2 x 40 mg tablets). You join them togther and keep an eye on the shade (strength). The 2 tins together did not cause a darker blue, they held the same shade as when they were in their own tins.

This is the same as combining 2 x 40 mg tablets. It doesnt make a higher dose, there is just more 40 mg moving around your body.

I hope this makes sense,
Tom.

PS: I have the actual 80 mg tablets as well a the 40 mg ones, the 80 mg ones are completely different looking. They are capsuals that contain lots of tiny little balls whereas the 40 mg tablets are just tiny little buttons.
