Other question 🤔 Concerta Is Completely Unavailable in Japan
Hello, I live in Japan.
I take 36 mg of Concerta every day, but pharmacies are receiving virtually no stock at all—not the 18 mg, 27 mg, or 36 mg strengths.
In Japan, we first obtain a prescription from our doctor, submit it to a dispensing pharmacy, and then receive the medication from the pharmacy.
My doctor prescribed me 36 mg Concerta a month ago, and I submitted the prescription to my pharmacy immediately. Unsurprisingly, they had none in stock, and they still have no idea when they will receive more. I now have only four doses left.
Every pharmacy I have contacted has told me the same thing: they have no estimated restock date.
Apparently, until a few months ago, pharmacies were receiving about one box of each strength per month. Now, however, they do not seem to be receiving any at all.
Only three medications are approved for treating adults with ADHD in Japan:
- Concerta (extended-release methylphenidate)
- Strattera (atomoxetine)
- Intuniv (guanfacine)
I have tried both Strattera and Intuniv, but neither worked for me. Strattera made my mind feel strangely quiet, which I found uncomfortable, while Intuniv significantly worsened my depression.
Honestly, I am angry with Japan’s Ministry of Health, Labour and Welfare.
Pharmacy-to-pharmacy transfers of Concerta were recently permitted as an exceptional measure. However, this is practically meaningless when the medication itself is barely being distributed anywhere.
In my case, only stimulant medications such as Concerta are effective and tolerable.
Vyvanse (lisdexamfetamine) is another stimulant ADHD medication, but in Japan it is approved only for children and generally cannot be prescribed to adults. Adults may continue taking it only as an exception if they began treatment with Vyvanse during childhood and it remains effective after they reach adulthood.
Immediate-release Ritalin (methylphenidate) was previously misused in Japan. As a result, its approved use is now restricted to narcolepsy, and it cannot be prescribed for ADHD.
At this point, rather than continuing to rely solely on Concerta, I would like Japan’s Ministry of Health, Labour and Welfare to consider the following exceptional measures:
- Expand Ritalin’s approved indication to include ADHD.
- Approve Vyvanse for the treatment of adults with ADHD.
Unfortunately, Japan’s regulations are extremely strict, so I doubt either change will happen.
This has become a serious social issue in Japan. Many people with ADHD say they can no longer function properly in their daily lives because they cannot obtain their medication, and I am one of them.
What is the current Concerta supply situation like in your country? Are alternative medications such as Vyvanse, Ritalin, or other treatments available to you?
