Pregnancy and breastfeeding: the essential warning

Do not take isotretinoin during pregnancy, when trying to become pregnant, or while breastfeeding. Even brief exposure in pregnancy can cause severe birth defects. If pregnancy occurs or is suspected during treatment, stop the medicine and contact the prescribing clinician immediately.

People who can become pregnant need the pregnancy testing, prevention measures and follow-up required by their prescriber and local programme. A small capsule strength does not remove this risk. Never share isotretinoin with another person.

What are isotretinoin capsules used for?

Oral isotretinoin is used for severe acne that has not responded adequately to other appropriate treatments. The UK product information includes severe nodular or conglobate acne and acne at risk of permanent scarring after standard treatment has failed. The US label describes severe recalcitrant nodular acne. Eligibility follows the applicable label and a clinician's assessment.

This is a prescription retinoid, not a routine cosmetic supplement. A dermatologist or another appropriately qualified prescriber decides whether its benefits justify the risks. Oral isotretinoin capsules and topical tretinoin products are different medicines and dosage forms.

10mg, 20mg and other strengths: check the formulation

The strength is the amount of isotretinoin in each capsule. A 10mg capsule and a 20mg capsule have different amounts per capsule; a pack containing 100 capsules describes quantity, not dose. A lower number is not evidence that a product is safe to start without supervision.

Formulation also matters. The US ABSORICA and ABSORICA LD labels specifically state that the two products are not substitutable milligram for milligram because their bioavailability and recommended dosing differ. Food instructions can also differ between formulations. Use the leaflet for the exact prescribed product and ask a pharmacist before any switch.

GME's catalogue currently lists 5mg, 10mg, 20mg, 24mg, 30mg and 40mg capsules. A catalogue title does not identify a particular patented formulation, establish equivalence to a reference brand, or confirm authorisation in a destination country. Confirm the manufacturer and full product label.

Monitoring and medicines to discuss with the prescriber

Clinical review commonly includes liver function and blood lipid tests, with pregnancy checks where relevant. The prescriber determines the schedule and any treatment changes. UK safety measures also call for assessment and monitoring of mental health and sexual function concerns.

Tell the prescriber about all medicines and supplements, particularly tetracycline antibiotics and vitamin A supplements, which should not be combined with isotretinoin. Do not give blood during treatment or for one month after stopping. Ask the treating team about skincare, sun exposure and cosmetic procedures. This guide provides no dose calculation or course-length recommendation.

Side effects and symptoms that need prompt help

Dry lips, dry skin and dry eyes are common. These can affect comfort and contact-lens use; ask a pharmacist or clinician about suitable care. Report persistent or troublesome effects rather than changing the capsule strength yourself.

Stop taking isotretinoin and seek urgent medical assessment for a severe headache with visual changes, severe abdominal pain, blistering or peeling skin, or a serious change in mood or behaviour. Facial swelling or breathing difficulty needs emergency help. New mental health or sexual function symptoms should be discussed promptly with the treating team. These examples do not replace the full product leaflet.

Preparing a precise product or export enquiry

For a product-information request, state isotretinoin, the required milligrams per capsule, the exact capsule formulation, preferred brand or manufacturer, pack quantity, total quantity and destination. Keep the number of capsules separate from the strength. Request the current product label and relevant documentation before assessing a proposed presentation.

Destination requirements can restrict prescribing, dispensing and distribution. In the United States, isotretinoin is subject to the iPLEDGE REMS programme. An export quotation or a catalogue listing does not replace those requirements or confirm that a shipment is permitted. GME's enquiry service concerns product information and documentation coordination; treatment decisions belong to the prescriber. Do not enter patient records or identity documents into the public enquiry form.

Export product support

Need product, pack, and documentation details?

Common questions

What is the difference between isotretinoin 10mg and 20mg capsules?

They contain different amounts of isotretinoin per capsule. The prescription also depends on the exact formulation and the patient's clinical assessment. Do not change the number of capsules or switch strengths without the prescriber or pharmacist.

Is a low-strength isotretinoin capsule safe during pregnancy?

No. Isotretinoin must not be used in pregnancy, and a low strength does not remove the risk of severe harm to an unborn baby. Pregnancy prevention and testing requirements still apply.

Can a 24mg capsule be converted to another isotretinoin strength?

Do not assume equivalence from the number. Some isotretinoin formulations have different bioavailability and are not substitutable milligram for milligram. Confirm the exact product label with a pharmacist; GME's catalogue title alone does not establish the formulation.

Should isotretinoin be taken with food?

Follow the leaflet for the exact prescribed formulation. Some conventional capsule labels specify food, while certain other formulations have different instructions. A general online guide cannot replace the individual product's directions.

Does a pack of 100 capsules describe the treatment dose?

No. It describes pack quantity. The amount in each capsule, the prescribed amount and frequency, and the number of capsules supplied are separate details.

Can an export enquiry replace a prescription or local distribution requirements?

No. Product information and quotation support do not replace prescribing, pharmacy, pregnancy-prevention or destination-market requirements. The US iPLEDGE REMS is one example of a restricted programme that buyers must consider.
