Hopefully he gave you more than one pill. Take it at home and see what affect it has on you. If dentist only gave you one pill, I'd make sure someone is driving you to and from the dentist appt.
Most likely will make you sleepy, which can be a good thing in a dentists chair. I would be cautious driving with valium use until you get used to it. Could you have someone drive you to the dentists that day? See how the valium makes you feel, judgement and reflex wise... if you seem "ok" then you know you can handle it. Good luck, but you should be fine.
P.S. Do not take valium with alcohol, it will just add to the effects of the medication and could cause a drunken state...excessive alcohol use with valium can cause breathing problems or worse.
I have taken up to 7mg at one time, and it didnt do too much to me, just calmed me. Cant your Doctor prescribe some 5mg and 2mg so you can take 7mg, i think 10mg might be a bit strong for you. One Doctor told me once that 10mg may make you lose control of your bladder function for a while, which i think is rubbish. Some people take 10mg on a daily basis. I have taken 2x 5mg in a day before , which really didnt affect me at all.
Try 7mg at home before you go . Like a week or so , see how you go with that , then you will know what to expect on the day.
Issy, I don't think your dentist would have prescribed 10 mg if it was an unsafe dose for you. I find that most drugs kick in within a half hour of taking it. You'll be fine. Once that 10 mg valium kicks in, you won't care about anything LOL
You'll be real drowsy and may have a hard time keeping your eyes open and will probably need a nap when you get home. Try to stop worrying now. It will not be nearly as bad as you have conjured up in your mind.
P.S. Post tomorrow night if you can and let us know how you made out.
Had Dentist yesterday. Got there 1 hour early & took 10mg Valium.
Within 20mins it was taking effect. So after an hour i felt like i had too much to drink ! Legs felt like heavy weights & Dentist had to help walk me into her room !
Was wonderful,appointment was 1 hour, but it honestly felt like 10mins !
Got another appointment in exactly 1 weeks time & this time i'm taking 5mg
It relaxes a part of the brain that drives our limbs, so it was telling your legs to relaxxxxxxxxxxxxx, they just relaxed a little too much on 10mg, its ok it wears off as you already know. At least it got you through the appointment. Well done.
