Ichijiku Enema 30 in Japan: Grams, Pack Counts and Age Are Different

Current Japanese manufacturer information and carton instructions checked: 2 November 2026. This guide covers the standard Ichijiku Enema 30 before purchase—not insertion instructions or directions shared with other sizes, 30E or overseas enemas.

The “30” is not an age recommendation. It means 30g of solution in each container. The separate numbers 2, 5, 10 or 20 describe how many containers come in a box. The actual age condition is separate: this product is for ages 12 and over, and meeting that condition does not make it suitable for everyone.

There is a more fundamental distinction: this is a rectal enema, not an oral laxative. If you entered the drugstore simply looking for “constipation medicine,” understanding the route and the consultation conditions matters more than choosing by the largest number on the carton.

Identify standard 30: one container is not the whole box

The full name is イチジク浣腸30 (Ichijiku Enema 30), a Japanese Class 2 OTC medicine indicated for constipation. The official photograph shows the standard container alongside four packaging examples: 30g × 2, 5, 10 and 20 containers. These are not four concentrations or four stages from children to adults.

This guide does not mix in 30E, 40, children’s versions or other brands. A similar shape or the word “enema” does not justify transferring quantities, age limits, container instructions or precautions between products.

Read three different kinds of number

• 30g is the quantity of solution in one container. Each 30g container contains 15.00g of Japanese Pharmacopoeia glycerin, with benzalkonium chloride as an additive and purified water. The 30g is not the weight of glycerin alone, an age or a score for effectiveness.
• 2, 5, 10 or 20 is the number of containers in the box. A larger box does not mean using more at once or using the whole box consecutively.
• Age 12 and over is the eligibility condition for this product. Do not use it in children under 12 or turn it into a children’s product by reducing the liquid. Meeting the age threshold still leaves the medical, symptom and pregnancy checks above.

The basic unit in the directions is one container (30g) per use for ages 12 and over, administered rectally. This identifies the label; it is not a complete administration guide. If you have not used it before, take the actual product and its complete official instructions to a professional before starting, rather than relying on this paragraph alone.

The same pharmacy shelf does not mean the same route

Oral tablets are taken by mouth; this product is for enema use only and must not be swallowed. Do not make a substitute with raw glycerin, transfer it into another container or copy instructions for a different enema. This article also does not diagnose suitability from a feeling that stool is “stuck near the exit.”

The carton warns that forcible insertion can damage the rectal lining. The complete instructions cover preparation, precautions after administration and what to do if it does not work; this guide does not turn insertion, waiting or additional quantities into a simplified procedure diagram. If you cannot understand the instructions or are unsure about using the container, ask a pharmacist or registered seller rather than repeatedly attempting it.

Wanting prompt relief does not make it a daily solution

Do not use this product continuously. The official instructions explain that habitual use may reduce its effect and encourage reliance on medicine. The number of containers in the box is not a number of days for treatment. Do not schedule it as a daily travel routine or add other laxatives yourself to meet a departure time.

If there is still no bowel movement after two to three uses, stop and take the instructions to a doctor, pharmacist or registered seller. This does not tell everyone to try three times first, or permit using three containers consecutively in one session. Existing consultation conditions or concerning symptoms should not wait for that threshold.

The instructions also list lightheadedness on standing, a sensation of heat around the anus and discomfort as possible symptoms. If something feels abnormal or you are unsure whether to use it again, seek advice rather than increasing the quantity. Recurrent constipation needs its cause assessed. Our travel-constipation guide covers everyday measures, urgent warning signs and information to take to the pharmacy; this article does not repeat a general self-selection pathway.

A useful question to ask at the pharmacy

Show the actual product and explain your age, last bowel movement, symptoms such as pain, nausea or bleeding, conditions under treatment, possible pregnancy, and medicines already used—including when and how often. You can ask: “This is a rectal product containing 30g per container, not an oral medicine—is that right? With my current symptoms, should I seek medical care before considering it?”

If a professional confirms that use is appropriate, clarify the complete instructions and what to do if it does not work. General statements in a brand FAQ do not cancel the carton’s pre-use consultation requirements. Another person’s suitability is not permission for you to combine products, increase quantities or use this continuously.

Keep the original packaging after purchase

Store away from direct sunlight in a cool place and out of children’s reach. Do not transfer the product to another container, which can lead to misuse or a change in quality. Do not use it after the expiry date. Keep the carton instructions; having unused containers left is not a reason to establish a regular dosing routine.
