Renova (Isotretinoin) – Patient Information (UK)

Renova contains isotretinoin, a medicine used to treat certain severe forms of acne. It works by targeting the root causes of acne in the skin, often leading to long-lasting improvement after a course. This page explains how Renova works, how it’s usually taken, important safety information, and practical tips for using it.

Important: Isotretinoin can cause serious side effects in some people and requires careful monitoring. Always follow the guidance of your healthcare professional and the medicine’s Patient Information Leaflet.

1. Basic product information

2. How Renova works (mechanism of action)

Acne forms when pores become blocked, oil production increases, inflammation develops, and acne-causing bacteria multiply. Isotretinoin helps by:

• Reducing sebum (skin oil) production by shrinking the oil glands.
• Normalising skin cell turnover to reduce pore blockages.
• Reducing inflammation, which helps calm painful, red acne lesions.
• Modifying the skin environment so acne-causing processes are less likely to continue.

Because it acts on multiple pathways, isotretinoin is often considered when other acne treatments have not worked well enough or when acne is likely to cause permanent scarring.

3. Pharmacokinetics (how the body handles isotretinoin)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and excreted. The key points for isotretinoin include:

• Absorption varies; taking isotretinoin with food can significantly increase absorption.
• Metabolism: isotretinoin is converted mainly in the liver to active metabolites (including tretinoin-related forms in the body).
• Half-life: isotretinoin and its metabolites persist in the body for days to weeks; this contributes to the need for ongoing safety precautions.
• Elimination: metabolites are cleared mainly through urine and bile/faeces.

These features are one reason why monitoring and adherence to dosing instructions matter throughout treatment and after stopping.

4. Typical use and timing

Who it’s commonly used for

Renova is commonly used for moderate to severe acne, particularly when:

• acne is likely to scar,
• acne is painful or inflammatory, or
• other treatments (such as topical therapies and oral antibiotics) have not been effective enough.

When you’ll notice changes

Many people notice improvement over time, but it’s not instant. A typical pattern:

• First few weeks: dryness is common; acne may appear to worsen briefly for some people.
• By 8–12 weeks: clearer improvement for many.
• Ongoing over the course: continued reduction in new lesions.

Your individual timeline can vary. Finishing the full course (as advised) is important for best outcomes.

5. Indications (what it treats)

Isotretinoin is indicated for severe acne and certain acne variants, such as:

• severe nodular acne
• acne at risk of permanent scarring
• acne that has not responded adequately to standard treatments

It should be used only for the conditions it is intended to treat. If you are unsure whether your acne type is suitable, discuss it with a clinician.

---

6. Dosing: what people typically take

Doses of isotretinoin are individualised based on factors such as age, severity of acne, tolerance, and treatment response. The most important message: follow your prescribed dose schedule exactly.

Common dosing approach

Clinicians often calculate a target total dose over the course of treatment (frequently expressed as mg per kg of body weight), then adjust the daily dose depending on side effects.

• Daily dosing: usually taken once or twice daily depending on the product and your plan.
• Course length: commonly around several months, with adjustments based on progress and tolerability.

Taking capsules

Capsules should be swallowed whole and not crushed or opened unless specifically instructed by your healthcare professional and the product instructions.

---

7. Food interactions (important)

Food can significantly affect absorption. Isotretinoin absorption is generally improved when taken with a meal. For best effect, take Renova with food as directed.

• If your dose is once daily, take it with your main meal.
• If your dose is twice daily, split with two meals.
• Try to take it at consistent times each day to help maintain steady exposure.

Avoid sudden major changes in diet without discussing with your clinician, especially if you notice a change in side effects or worsening acne.

---

8. Alcohol and medicine interactions

Alcohol

Isotretinoin can affect liver function and may also influence blood lipid levels. Alcohol can also stress the liver. For safety, it’s often recommended to limit alcohol during treatment, particularly if you have a history of liver problems or abnormal blood tests.

If you drink alcohol, discuss what’s safe for you with a clinician based on your results and risk factors.

Medicines and supplements to be careful with

Several medicines may interact with isotretinoin. Always tell your healthcare professional about:

• all prescription medicines and over-the-counter products
• herbal supplements (including “natural” products)
• vitamins, especially those related to vitamin A

Particular caution:

• Other vitamin A (retinoids) or vitamin A supplements: combining increases the risk of vitamin A–related toxicity.
• Tetracycline antibiotics (such as doxycycline, minocycline): there is concern about increased risk of raised intracranial pressure.
• Certain acne treatments: combining with other strong keratolytics or irritants may worsen dryness and irritation.
• Medicines affecting liver or blood fats: may increase monitoring needs.

If you start any new medicine during isotretinoin treatment, check with your healthcare professional or pharmacist to confirm it’s compatible.

9. Safety profile: what to expect and when to get help

Renova (isotretinoin) is effective but has important safety considerations. Side effects are often related to reduced oil production and changes in skin/mucosa, but serious effects can also occur.

Common side effects

• Dry lips (cheilitis) and cracked corners of the mouth
• Dry skin and peeling
• Dry eyes, eye irritation, or sensitivity to contact lenses
• Dry nose and possible nosebleeds
• Sun sensitivity: skin may burn more easily
• Muscle or joint aches
• Temporary increase in acne early in treatment (sometimes called a “flare”)
• Changes in blood lipids (e.g., triglycerides)
• Changes in liver enzymes on blood tests

Serious or urgent warning signs

Seek urgent medical advice if you experience symptoms such as:

• Severe headache, blurred vision, or vision changes (possible raised intracranial pressure)
• Severe mood changes, depression, agitation, or thoughts of self-harm
• Allergic reaction: swelling of face/lips, difficulty breathing, widespread rash
• Severe abdominal pain or persistent vomiting (possible pancreatitis)
• Signs of liver problems: yellowing of skin/eyes, dark urine, severe fatigue
• Vision problems such as night vision difficulties that are new or worsening
• Severe skin reactions: blistering, peeling, or widespread rash

Pregnancy prevention is essential

Isotretinoin can cause severe birth defects if taken during pregnancy. This is one of the most critical safety issues. If you can become pregnant or have a partner who can become pregnant, strict precautions are required, including pregnancy prevention measures and adherence to the UK requirements set by the medicine’s risk minimisation programme.

If pregnancy occurs or is suspected, contact a healthcare professional immediately for urgent advice.

Blood tests and monitoring

During treatment, clinicians commonly monitor:

• liver function (liver enzymes)
• blood lipids (triglycerides and cholesterol)
• full clinical progress and side effects

Follow the schedule you’re given. Monitoring helps ensure safety and allows dose adjustments if needed.

10. Practical use tips (making treatment easier)

Many people manage isotretinoin side effects successfully with good skincare and lifestyle habits. The tips below are general; confirm details with your healthcare professional, particularly if you have eczema, rosacea, or very sensitive skin.

Skincare routine

• Use gentle cleansers (fragrance-free where possible).
• Moisturise regularly with bland emollients to reduce irritation.
• Lip balm often: choose a moisturising, non-irritating balm and reapply frequently.
• Avoid harsh exfoliants (scrubs, strong acids) unless specifically advised.
• Sun protection is crucial: use broad-spectrum sunscreen and protective clothing.

Contact lenses and eyes

• If you wear contact lenses and notice discomfort or dryness, consider switching to glasses temporarily.
• Lubricating eye drops may help—ask your pharmacist about suitable products.

Exercise and muscle/joint comfort

• Some people experience muscle aches. Consider reducing intensity if you feel unusually sore.
• Stay hydrated and stretch gently, especially at the start of treatment.

Avoid skin injuries and irritation

• Try to avoid waxing or aggressive skin procedures during treatment if your skin is very fragile.
• Handle shaving gently; consider an electric trimmer to reduce nicks and irritation.

What to do if side effects are bothersome

Don’t stop the medicine suddenly without medical advice. Instead, discuss your symptoms promptly; clinicians can adjust the dose, change supportive treatments, or offer strategies to improve comfort.
