|---|---|
| Drug Class | Retinoid (Vitamin A derivative) |
| Active Ingredient | Isotretinoin |

Tretiva 20 MG Capsule is a powerful systemic retinoid medicine. It contains the active ingredient isotretinoin, which is derived naturally from vitamin A.
In the UK, this is a strict prescription-only medicine (POM). Like Roaccutane, it requires initiation by a specialist dermatologist and regular clinical monitoring.
How Isotretinoin Works in the Body
The active ingredient targets the root causes of severe acne breakouts. This medicine works directly on the sebaceous glands. These are the oil-producing glands found in your skin.
The medicine significantly reduces sebum production (the natural skin oil). Skin pores become less likely to block when oil production decreases.
It also exhibits strong anti-inflammatory action to reduce redness. This biological process helps clear deep, painful lesions.
When Doctors Prescribe Tretiva 20 MG Capsule
Dermatologists prescribe this medicine for severe nodular acne. Nodular acne causes large, painful, firm lumps deep under the skin surface.
Doctors only consider this option when other treatments fail. This includes standard topical creams and oral antibiotics.
It serves as a highly targeted treatment for persistent, scarring acne variants. Before treatment begins, your specialist will confirm that it is suitable for you, just as they would when prescribing Roaccutane.
Benefits of Tretiva 20 MG Capsule
This treatment offers profound clinical benefits for severe skin conditions. It provides long-term clearance of painful, inflamed nodules.
For many patients, skin texture improves significantly during treatment. The therapy helps prevent permanent physical skin scarring.
Successful treatment often restores personal confidence and wellbeing. It delivers controlled, reliable results under medical care.
Alternative Medicine Doctors May Consider
Doctors may consider other options within the same therapeutic category. Topical retinoids like adapalene serve as milder alternatives.
Oral antibiotics combined with specialised skin gels are often tried first. For some female patients, specific contraceptive pills help regulate hormonal acne.
You can learn more about dermatological treatments through your specialist. See available treatment options by consulting your GP.
Possible Side Effects
| Frequency | Side Effects | Action Required |
|---|---|---|
| Common | Cracked lips, dry skin, dry eyes, mild nosebleeds | Apply moisturisers and lip balms frequently |
| Less Common | Changes in skin colour, thinning hair, and swollen gums | Inform your clinic at your next visit |
| Rare / Serious | Mood changes, severe headache, visual disturbances | — |
Should this happen, you must stop taking the medicine immediately and seek urgent medical help.
Most patients experience dry skin and chapped lips during therapy. These effects are predictable and manageable with moisturising balms.
Although uncommon, serious side effects need urgent medical attention when they do occur. Watch for severe headaches or changes in your vision.
Any unexpected side effects should be reported to the MHRA Yellow Card scheme. If any side effects become troublesome, you should always let your doctor know.
Important Safety Advice
This medication requires strict adherence to safety protocols. Sharing this medicine with anyone else is never permitted, as it has been prescribed solely for you.
Pregnancy and Contraception
Isotretinoin causes severe birth defects in an unborn fetus. Female patients must use multiple effective methods of contraception as mandated by the UK Pregnancy Prevention Programme.
Alcohol Interaction
Do not drink alcohol during your treatment course. Alcohol increases the risk of rapid heartbeat and liver strain.
Sun Sensitivity
This medicine makes your skin highly sensitive to sunlight. Wear high-SPF sunscreen and avoid direct, harsh exposure.
Blood Donation
Blood donation should be avoided both during treatment and for 1 month after stopping it. This protects pregnant transfusion recipients from exposure.
When Should You Speak to a Doctor?
Contact your specialist immediately if your mood changes. Watch for signs of depression, anxiety, or unusual sadness.
Seek urgent care if you experience severe abdominal pain or persistent vomiting. Do not ignore ringing in your ears or changes in your hearing.
If your skin condition worsens significantly, speak to your doctor, as your healthcare team is there to support you safely throughout treatment.
