Kim DiclegisIt was only a matter of time before Kim Kardashian posted a picture on her Instagram account with a bottle of Diclegis, basically announcing her brand partnership with Duchesnay, the manufacturer of the prescription medication for nausea and vomiting in pregnancy. Duchesnay had been tweeting for ages that they were so relieved Kim had found help with Diclegis – so much so that I was wondering if Ms. Kardashian was possibly having the longest first trimester known to womankind.

While the FDA was all over the Instagram post, I suppose they didn’t jump on the promoted tweets (which sure looked like advertising to me), because the link in the tweet took you to a page that actually listed side effects and contraindications. Although I think promoted tweets with a celebrity name is a pretty sly way around the rules. How many people really click through and read the fine print versus bring up a screen shot of the promoted tweet and ask their doctor for the medication that helped Kim?

But the FDA aside, I find Ms. Kardashian’s claim that she found the drug on her own somewhat surprising. She has an OB and honestly I have a hard time imagining her doctor not bringing it up if she mentioned an issue with nausea and or vomiting. The cynic in me wonders if her doctor only mentioned the over-the-counter (OTC) option.

Yes, while you can buy Diclegis as a prescription it is just a combination of two readily over-the counter (OTC) medications –cost diclegisvitamin B6 and doxylamine (an antihistamine) with slightly different dosing. When taken together doxylamine and vitamin B6 are mildly to moderately effective for nausea and vomiting in pregnancy. The difference between the prescription and the OTC is a minor variation in dose and the prescription is delayed-release so it is only taken once a day. However, there has been no head to head comparison between the OTC and prescription so we have no idea if the delayed-release offers any advantage beyond the convenience of one-daily dosing.

The big difference between the OTC option and Diclegis is price. You can buy 100 doxylamine 25 mg tablets for $12.79 and 100 vitamin B6 tablets 25 mg for $7.29 (see below) and you can bet the manufacturers are still making a profit. Diclegis, if you have a coupon, is $345 for 60 tablets. The dose is two tablets a day, but some women need four tablets so the cost for could be $690 a month (with discount coupon!). Some may get it covered by insurance, but even then co payments are likely to be $20 or more. You will pay at most $25.20 a month for OTC (less if you don’t need four pills a day and/or take advantage of the buy one get the other 50% off at Walgreens). The other advantage of the OTC route is you can start with vitamin B6 and if that doesn’t work then add in the doxylamine. After all, we recommend a step wise approach to nausea and vomiting.

Let’s compare OTC doxylamine/vitamin B6 with Diclegis. The OTC dosing is not identical but close enough and before 2013 (when Diclegis wasn’t available) we managed just fine using these slightly different doses. Check out this table:

Diclegis table

While doxylamine and vitamin B6 may help many pregnant women, for most Diclegis is an unnecessary medication. I’m not saying unnecessary to downplay nausea and vomiting – I suffered terribly in my pregnancy with nausea so I am very empathetic. I’m saying unnecessary because at that price and without studies showing medical benefit of a delayed-release formulation the prescription should only be considered if the OTC version isn’t working, Perhaps for some women the delayed-release might be better and since there are more studies on doxylamine/vitamin B6 than other options it makes sense to step up to this after trying the OTC option and before other prescriptions are tried.

If your insurer pays for you to take Diclegis and you haven’t tried and failed the OTC combination that’s several hundred dollars that could have been spent elsewhere. Your insurer will make up the difference somewhere, typically by higher co-payments for delivery.

Every single OB/GYN and pharmacist I know believes Diclegis came out with the delayed-release formulation to break into the amazingly Pharma friendly US health care market because they knew they could do minimal work and charge insurers a bazillion dollars. In fact, when I retire and no longer have to worry about conflicts of interest I will invest in Big Pharma because they literally get away with crippling the American Health care system. OK, probably not because I want my kids to be able to afford health care and I want to sleep at night, but you get the idea.

Diclegis is nothing special – it’s no brand new wonder drug. If it had been studied head to head with the OTC products and found to be clearly superior that would be different. It’s hard to make sense of a regulatory agency that is primed for this kind of manipulation.

Meanwhile, I’m just waiting to see what birth control pill or IUD Ms. Kardashian is going to talk about once her seemingly eternal pregnancy comes to fruition I’m sure she has learned a marketing lesson and instead of an Instagram photo shoot complete with full make up and fake eyelashes (because that is exactly how Diclegis makes you feel, right?! ) it will be casually dropped in conversation on her show or in an interview. Hey, maybe you will be able to buy a digital version in her game!

I wonder how many Birkin Bags the insurance companies (and hence your dollars) are buying for Ms. Kardashian through the middle men at Duchesnay. And remember, no matter how much they are paying Ms. Kardashian the folks at Duchesnay are making exponentially more. Remember, $5.75 for a pill that makes a profit at $0.21. vit B

  1. I tried the OTC at the max safe dose. It helped a little. But the my doctor gave me a sample bottle of Diclegis. THEY DON’T EVEN COMPARE. I felt immediate relief. I’m now 19 weeks, still suffering from N/V all day, except for the days i take Diclegis. (i save them for the days i work since they’re so expensive! I’m able to work full time as a nurse in the ICU still.)

  2. Diclegis is not the same thing as B6 + unisom at all. Diclegis provides a continuous dose in a different delivery system. I could see the OTC hack working quite well for someone with normal morning sickness that is not continuous vomiting / nausea but if you have severe sickness or hyperemesis gravidarum, it’s unlikely to work. I tried it and it did nothing for me. Diclegis was a massive relief and made me able to function and hold down food and fluids. And for some people the sickness doesn’t end with the first trimester. It can last into the second trimester or for the whole pregnancy. For some of us, Diclegis is not a luxury, it’s a necessity. So please think before blogging so irresponsibly about a medication. This really harms availability of the drug, its price, and stops women from asking for the help they need. There are coupons available on the Diclegis website that bring the cost down to about $40, even without insurance. So it can’t really be compared to a luxury (and unnecessary) handbag purchase.

  3. I’m surprised. Yes the drug has been around for 60 years and what the drug company charges is ridiculously overpriced and unjustifiably so. However, it is effective, (almost 100% effectiveness), which is unheard of. It’s also a class A drug for pregnant women, the safest for her unborn baby,rare. It’s also the only one specifically recommended by the FDA to treat morning sickness. Other drugs are used by doctors off label for pregnancy. As a doctor, it’s irresponsible of you not to recognize this fact. Diclegis was safer and effective than Zofran, which I’ve taken in the past twice for Hyperemesis gravidarum and still ended up hospitalized for dehydration due to the Zofran being unable to effectively stop my nausea and vomiting. The idea is to get ahead of morning sickness before it happens. This does that. My insurance covers only 100 out of 450. So my copayment with an excellent ppo is still 350 out of pocket, which is insane. The drug manufacturer provides a coupon so the total is 100. It’s wrong for the price to be so high and I don’t argue that. It’s criminal. However, the drug itself is the best option and you should be fighting for all women who need the relief to have inexpensive effective access to it. It’s saving my bacon this time around and I don’t give a rodent’s behind who advertises it. I care about not being hospitalized and having a safe pregnancy. Taking two pills a night before bed gives me the next day nausea free and it’s so liberating I could weep! Women deserve relief. Pregnancy is stressful enough.

  4. Diclegis could lower their ridiculous prices if they didn’t pay these already rich celebrities to promote it. There are a lot of pregnant women who really needs this medicine; but can’t afford it, Duchnesay claims to care about women’health , but all they care about is making money ,
