Common Questions and Answers about Cialis half life

Avatar m tn I am considering switching from Levitra to Cialis. Have read that Cialis has a longer half life (up to 36 hrs vs. 5-7 hrs.). Anyway, I have tried extending Levitra's half-life by taking a second dosage a few hours later, but no matter what, the max effects still really fade off 5-7 hours after the initial dosage. Wondering if anyone knows why this might be... and why a second dose would not extend the effects? Just helps with planning.
Avatar f tn I have some erectile dysfunction due to having to be on beta blockers. I've been prescribed Cialis 5mg once a day, but haven't gotten up the courage to take one yet. Kind of afraid to be honest. I know many many take it with no problem, but I have a tendancy to feel my heart race more than usual during sex and at random times, which is why I take the beta blockers, but I'm not having a normal sex life. I know my doctor knows what's best.
Avatar n tn I am 51 & have been using Cialis 20 mg for about a year it worked great for about 10 months. It has stopped working the last 2 months. I had my testosterone checked it was 392. My PSA result was 0.68 ng/mL. But I do have some mild prostate pain. I was married for 31 years & have had ED problems for years. I was divorced a year & a half ago. & have had a beautiful new woman in my life for the last 14 months or so.
Avatar m tn If you're worried about side effects, I'd start with half, or even a quarter, of a pill because Cialis lasts so long. That is, if it turns your face red, it may stay that way for 24 hours, versus just a few hours for Viagra. You can always take more later, but you can't undo what you've taken!
Avatar f tn I read some place that men with small penises (my penis has 13 cm when engorged ) need to take smaller doses of Cialis ( or Viagra ) because, if they don't, they can have anorgarmia ( the penis has erections but you can't ejaculate ). Is that true ? I ask this because that happened to me. I'm 70 y.o.
Avatar f tn The half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. Hope that helps.
6298176 tn?1380134459 It has a very long half life, though I can't give you specifics. The dose and how long you were on it does factor in. Your doctor should be able to help you with your questions on this.
Avatar m tn However, it does, or certainly can, block messages from brain to penis resulting in the collapse of erection. Before trying Viagra or Cialis it is always worth trying to de-emphasis intercourse, just enjoy each other's bodies then, in a week or so you take over while he just lies there and does nothing.
Avatar m tn I was once given a 20mg Cialis pill by a friend and broke it in half. So I took around 10mg dosage. I cannot afford Cialis through my insurance so I was going to try the free sample voucher on their website. They have 2 different options. the every day dosage of 5mg or the 20mg dosage for one time use. I don't have an all the time problem, so I would be taking it on occasion. The thing is you only get 3 pills of one time use and 30 5mg pills. Are they the exact same thing?
Avatar f tn I'm 33, slim, in decent health, not overweight at all, for about the past year or so, I've been experiencing some erectile dysfunction. Not entirely, but basically what happens is I can get an erection if I'm turned on or if it's been a while since I last ejaculated, but I have trouble maintaining the erection during sex. I notice that it might start out fine but then about half way in I'll get somewhat soft or even totally soft then get hard, and back again.
Avatar m tn I don't have ED but I was curious if my erections could be stronger. I spoke with my doctor and tried Cialis and Viagra. Since they have much different half-lives, I thought I'd try the following: Taking 10-20 mg Cialis every 2-3 days, then taking 20-40 mg Viagra (generic sildenafil) before sexual activity. My questions isn't whether this is effective - it certainly is. But is there any risk to doing this? I moved so I don't have a doctor right now.
Avatar f tn I'm a 33yo guy, in overall good health, I've been on a low dose of Metoprolol for about a year for benign tachycardia. I've cut my dose down to 25 mg a day since I noticed I began having trouble maintaining erections more than I'd like. Used to never have that issue. I've gotten prescribed Cialis 5mg, haven't taken it yet, is it safe for the heart to take? Like it won't trigger any dangerous rhythms or anything? Really wanting to get my sex life back.
Avatar m tn So I am 19 years old, and have a history of situational erectile dysfunction - by which I mean I get erections perfectly fine in the mornings, alone, while kissing or making out, but it them disappears when I try to have penetrative sex. This is very troublesome to my personal life. I am now with my third girlfriend and have only ever had sex twice. In an attempt to get over whatever the problem is, I took a Cialis pill this morning at around 8:00 AM, 5 hours ago.
Avatar m tn If i watch porn (i dont do this often) i will quite often get an erection, and if i havent been taking any ED drugs i still get morning erections about half the time... yet when it comes to having sex with my partner i now need cialis to have any hope of being hard at all...and this is driving me insane. Anyway question is, does this sound like ED?. And...does anyone have experience with levitra?. I have read its shorter lasting but more potent than cialis. Thanks.
Avatar m tn Where can i order cialis online? What is the most dependable and trusted pharmacy? Basically im looking to purchase viagra/cialis (not necessarily the trademark brands, but something that works the same) online, because its much cheaper. However i have no idea where to look, and theres just too numerous scam sites around. So i was wondering whether anyone knew a good forum community which could help me and advise me on where to buy these kind of Ed treatment pills.
Avatar m tn Had prostrate surgery 6 months ago, benign prostrate hyper something, it was enlarged. So ED has caused some changes. I call it turtle mode, my little buddy has retracted like a turtle to its shell, he doesn't dangle anymore which may have been from the green light laser surgery, maybe some nerve issues, I can get an erection with help but not hard enough for intercourse.
Avatar m tn The Cialis only started working about 3 and a half hours after taking it. Then it lasted for 2 or maybe 3 days. In that time it was easy to get it up. I would recommend it (on it's own) and I would say it's better than Levitra.
Avatar f tn Can't help you with the sex life part, as I'm a female, but I can share my experience switching from a beta blocker to diltiazem. I have been taking beta blockers for 8 years for SVT and afib. I had an episode of afib and was in the hospital is Sept. They took me off the beta blocker and put me on diltiazem. It didn't control my heart rate like the beta blocker. My resting heart rate went from upper 60s to the low 80s.
Avatar f tn So I'm starting Cialis 5mg a day as needed for erectile dysfunction due to side effects from Metoprolol. I've cut down my dose of Metoprolol to about 37.5mg a day. I have no lack of interest, just my penis goes soft without manual stimulation. If I stroke it, fine, but if I'm having sex, for the last year or so, since I started the meds, it will periodically go soft without constant stroking which is highly annoying. I'm only 33 too.
Avatar f tn it may be that the Cialis you received from the internet may be fake cialis - I would try to get a proper Rx from a doctor/phamacy there.
