“Denavir works amazing for me but my insurance won’t cover cost anymore and way too expensive ($900) for me to pay out of pocket. My doctor who works for large medical group in U. S. says they’re not allowed to send my prescription to Canada where cost for me would be about $50. Patent has finally expired and I’m hoping a generic version will eventually be available”

“Denavir is the ONLY medicine that works to stop cold sore for me! Don't understand why no generic available and why the Brand price go insane. People try to convince Abreva can do the magic! Abreva is totally worthless for me compared to Denavir but it seems that is only available brand on the market that claim target to cold sore. There are no medicines that really work like Denavir for cold sore not even Zovirax as least that is what from my experience. Denavir really stop Cold Sore once you apply on it! It is magic ... so disappointed the price of Denavir is so unreachable!!!!!”

“I’m at a loss for words when I just submitted for a refill !!! Wth?? I will continue to “nurse” my old tube till completely gone and search out a family member in Europe to get me a new tube. How dare this company charge this $948/tube for a cold sore med.... sure our politicians would like to be advised and I’ll be glad to write that letter.”

“I've used Denavir for decades. It worked well and was covered by my insurance. I've never paid more than a few dollars for a co-pay. Now it's almost $1,000 for a tiny tube that only lasts for one outbreak. This is ridiculous. My husband is very fair skinned and simple exposure to sunlight can bring on blistering on his lips that is so bad that his lips split and bleed. The only thing that has ever helped is Denavir - now we can't afford it and he will have to suffer through weeks and weeks of not being able to talk, eat, or drink without bleeding or pain. Denavir may get a 10 for effectiveness - but it gets a ZERO for actual effectiveness because now we can't afford it.”

“This drug does work wonders, but as stated here by almost everyone, it is prohibitively expensive. Order it online from in Canada, fax them your Rx, it comes from Europe, 3 - 2oz tubes cost me $113.76.”

“Denavir always worked great, but a few years ago in the US, they raised the price to nearly $900 a tube. Last year, in Greece, I saw the European version of the drug being sold over the counter for 7 Euros or about US$ 8. On top of that, it was being sold over the counter. It was exactly the same strength, and it had exactly the same packaging in Greece as it does in the US, with the exception that the name was Fenivir instead of Denavir. How is it that they can charge $8 for something in Greece, and they charge $900 in the US!!”

“I’ve been taking Denavir for over 15 years and it’s the only thing that gets rid of a cold sore quickly. Since it was sold to another company the price has skyrocketed. It wasn’t cheap to start with, but now it’s about $1,000+ per tiny tube. When my copay jumped from $20 to $800 I tried valacyclovir, which just caused the cold sore to subside and return over and over. We tried different dosages, but the result was constant cold sores for weeks. I’m going on vacation soon, and saw that the European version is sold over the counter, so I’m going to a pharmacy to buy some. It looks like it will cost less than 10 euros per tube, and is made by Novartis, the original creator. The brand name is Fenavir. So, if you have a friend or family member traveling to Europe, keep this in mind.”

“I have just started using this medicine on my cold sore and am really happy with it. I am in Europe and paid $7 for it. I cannot believe how much they charge you in the states, that is a ridiculous price ”

“Denavir works great for my occasional cold sore. However, it's not covered by my insurance as of 11/14/19. The pharmacist told me the out of pocket cost would be $800.00, and there's no generic medicine. I was beyond belief and outraged by the cost!! SHAME on the company, Mylan, for charging such an unreasonable/greedy price!!!!”

“Penciclovir is the active ingredient and it does work to clear cold sores faster. For those wondering why it costs $700+ in the USA, & less than $20 in other countries, the reason is because the USA has been unsuccessrful in purchasing pharmaceuticals at discounted prices. The more countries that get discounts, the more the USA has to pay because drug companies want to cover their losses. Europe's ability to buy cheap medication depends on the pharmaceutical companies' assumption that the USA will pay full price plus enough to cover the discount to X country in Europe. Other countries' bargaining directly affects American drug prices. Americans need to put pressure on politicians and insist on drug bargaining to make healthcare affordable.”

“On board with all previous posts. The cost is absolutely ludicrous. I call it my GOLD medication. I fortunately had a wonderful Doctor who jumped through hoops and did all she could to get pre approval via medicare. I've used this medication for years and last year was the first time I had an issue with coverage. It still took 4 months to finally get approval. But, I got it and well worth the wait. I get sores whenever I'm stressed, sick or out in the sun too long. It's the only one I've used that actually works and takes the cracked, burning, scabbing and painful 4 weeks of healing down to 1 week without cracking and pain. This is a great medication. But, yep the cost is beyond comprehension. I feel for all of you and hope that you can get a doctor to help with the red tape to get it approved.”

“Went to the Dr and paid a $30.00 co-pay to get a prescription renewal for Denavir for cold sores. Went to the pharmacy and was told the insurance refused to allow it to be filled because the drug now costs $700.00. What did Novartis find out? Can this stuff can cure Cancer and are trying to fund to research? It's been around for years and has plenty of competitors. This is totally ridiculous. Plenty of online places out of the US offering to sell two tubes for 40.00. What gives?”

“I too can attest the same thing every one has said. It is the best cold sore medicine on the market. It will cut the outbreak time to a few days, opposed to the 2-3 weeks. Unfortunately, I was blown away this week at the retail cost of this prescription. I have been using this medication for over 15 years and my insurance has always covered it. The most being $40 for the small tube. Now, my new insurance does not cover it, and I found the price at the pharmacy is charging is $795. I cannot pay this price and the coupon on the internet only offers up to $45. I feel screwed/gauged by this pharmaceutical company (New American Therapeutic) who purchased the rights to this medication in 2010 by Norvatis. No generic is available.”

“Unless you have money to burn, don’t support the millionaires that are scamming the average working person- it does work well but take your $1000 and have a vacation in Europe and at the same time pick up a couple of tubes of a similar cream of the same composition”

“Works great BUT what is going on!!! It was $50 last year and this year it is $856!!!! Crazy!! Is this because it is coming off patent soon??? So disappointed. I can’t believe Novartis is taking advantage in this way!”

“Denavir doesn’t really lessen the length of an outbreak for me, but it almost 100% gets rid of the pain and tingling. It might lessen the length by 2-3 days, but the relief from pain is what I use it for. Unfortunately, it’s not covered by my insurance and is $800. Can get in Canada for $40 with a prescription.”

“I am just trying it now, in 2 days my cold sore hasn't dried yet as it normally does with Urgo. In Europe Denavir (Fenivir is the name here) only costs 10 eur, how the hell can it cost $700 in the US??”

“Great product. I've had cold sores since I was a kid (40+ years). I carry this product with me all the time. Usually get a cold sore two / three times a year but when I do, I'm ready. Real important, the moment you feel the tingle apply the med. Usually heals the sore in 3-4 days, but better than the normal 8-10 days. Earlier comment stated, do not squeeze the tube, that is correct. Even a slight squeeze you will waist alot. I usually store it (tube) in the prescription bottle that it comes in.”

“It works okay I think, but the price increase from three years ago is mind-boggling. I would never have paid it but the pharmacy service covered by my insurance got my money and won't give it back. I am appalled that a drug company can do this but not at all surprised.”

“This is the best stuff for cold sores! Use it right away when you feel that tingle sensation and a cold sore may never appear. I also take Valtrex right away and both of these together can make it so that a cold sore never appears or if it does it’s gone in 2 days. Works great!”

“I have tried every OTC and Rx known to man to treat my cold sores. When I get an eruption, it is SEVERE. I blister up and my whole lip swells and it takes 3 weeks to heal without Denavir. If I use Denavir w ithin two days of use my cold sore is barely perceptible and 90% healed. No vesicle formation or crusty exudate. Just really fast healing. Nothing stops cold sores in their tracks as fast as Denavir topical. It is very expensive but a little goes a long way. I had my PCP do a prior auth for this medication and I did not blink an eye at the $70 co-pay and I am on a budget. Worth every penny.”

“I've been getting cold sores for as long as I can remember. Usually triggered by stress, but sometimes for no reason at all. Over the years I've tried EVERYTHING, Zovirax..whatever was the new product on the market. Denavir is the best topical ointment. But like everyone states, you must apply it as soon as possible - for me by the time I feel a slight tingle, it's too late. I was at work this time when I felt my lip tingle and literally ran home to get my Denavir. I suggest you carry the small tube in your wallet as I do now. I keep one at home, at work, and in my wallet - early application makes a huge difference in duration of cold sore. It's expensive - but worth it. One tip so as not to waste it - don't squeeze.”

“Had cold sores on lips & nose regularly since childhood. But not in the 10 or more years that I've had a Denavir prescription. In that time, if I apply at the first tingle, it rarely ever breaks through to become a sore. It has been a blessing. The cost is ridiculous. $700 plus, with a ~$175 insurance co-pay usually. Almost fainted last time I refilled, as CVS listed a $135 coupon on the receipt, so I wound up paying only $20. Do not know what that was about (asked no questions). I skipped out of the pharmacy quickly and enjoyed my surprise Christmas present!”

“Used it for years, works great but the side effect is empty pockets. Even with insurance, it costs $174, $700 w/o. You would think it is a life saving drug. Like the others, used to be a max $30 copay. My Dr. said to try otc Cortizone as soon as I feel a cold sore coming on, it actually works for me and costs under $10!!!”

“this is the best solution to nasty cold sores... If you are reading these reviews to get an idea about this medicine, stop now and order one right now. Believe everything every person is saying here about this cream. It is a miracle cream on every use.”

“Best cold sore product available. I've been getting cold sores for years and each outbreak usually puts me in hiding for at least a week. Denavir usually keeps it from forming into breakouts and cuts breakout times by 2/3s. Coupons are available on the company's product site to help defray the substantial costs for the medicine. As someone who has suffered breakouts for years, I'd recommend this product at any price. But it's nice to have a coupon to make it more affordable.”

“I have suffered from occasional fever blisters since childhood. As a teen and adult, they are embarrassing. Stress can do it, and also, if my body is fighting off an illness, which I suppose is stressful for the body. For many years, as soon as I feel the tingling of a new one beginning, I put Denavir on and it can stop it cold. It is truly an effective drug. Over-the-counter treatments do not work. Denavir does. I ask my doctor for occasional prescriptions just so I always have it in the house, even though I don't get them nearly as often anymore.”
