Warnings and precautions

Talk to your doctor or pharmacist before starting to use Retirides 1 mg/g cream

• take special care if you have eczema, as this medicine may cause skin irritation. If your skin is irritated, it is advisable to wait until the irritation has resolved before starting treatment with Retirides 1 mg/g cream.
• care should be taken to avoid contact with the eyes, eyelids, corners of the nose, mouth, mucous membranes, or other areas where treatment is not indicated, to minimize potential additional skin irritation. Care should be taken not to leave accumulated medication in skin folds. There is an increased risk of irritation in more sensitive skin areas such as the neck and forearms; therefore, it is recommended to reduce the frequency of application.
• exposure to sunlight, including ultraviolet (UVA) sunlamps, should be avoided or minimized during treatment with tretinoin. Patients with sunburn should be advised not to use the product until they have fully recovered. When sun exposure cannot be avoided, sunscreen products (minimum sun protection factor SPF 15) and protective clothing should be used on treated areas.
• if you experience persistent or severe irritation, you should completely stop applying Retirides 1 mg/g cream and, if necessary, consult your doctor.

3. How to use Retirides 1 mg/g cream

Follow exactly the instructions for use of this medicine as given by your doctor. If in doubt, consult your doctor again.

Depending on skin type and severity of the condition, at the physician's discretion, the cream of the appropriate concentration will be prescribed (since Retirides is available in concentrations of 0.25 mg/g, 0.5 mg/g, and 1 mg/g), and the number of daily applications will be recommended.

Treatment should be initiated with the lowest concentration cream (0.25 mg/g), applied once daily. Subsequently, and according to the individual patient's response, the concentration of the cream and/or the number of applications may be increased.

Avoid frequent washing of the face. Washing two or three times a day is sufficient, using a neutral soap and taking care to dry gently without rubbing.

Do not apply the cream until at least half an hour after washing the face.

Apply a sufficient amount of cream to cover the affected area and gently massage, avoiding contact with the eyes, eyelids, corners of the nose, mouth, and mucous membranes.

In any case, your doctor will determine the duration of your treatment with Retirides 1 mg/g cream.

In acne treatments, irritation is directly linked to the efficacy of the product and subsides when applications are spaced out. During the first weeks of treatment, an apparent worsening of symptoms and signs of irritation may occur. This reaction is normal, as it reflects the accelerated elimination of microcysts forming deep within the skin.

Excessive application of Retirides 1 mg/g cream does not improve treatment outcomes and may instead cause marked irritation, including redness, peeling, itching, etc.

During treatment, cosmetics may be used concurrently, particularly moisturizing products, but they should not be applied to the skin at the same time as the cream.

If you use more Retirides 1 mg/g cream than you should

If you have used more Retirides 1 mg/g cream than recommended, consult your doctor or pharmacist immediately.

Oral ingestion of Retirides 1 mg/g cream may lead to effects similar to those associated with excessive oral intake of vitamin A, for example, pruritus, skin dryness, arthralgia (neuralgia or joint pain), anorexia, vomiting, etc.

In case of overdose or accidental ingestion, contact the National Toxicology Information Service at Tel. 91 5620420.

If you have any further questions about the use of this product, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, this medicine may cause adverse effects, although not everyone experiences them.

Topical application of Retirides 1 mg/g cream may cause transient itching, sensation of warmth, slight redness, and skin peeling similar to mild sunburn, dryness, severe local erythema, development of edema at the application site, burns, blisters, ulcers, and pruritus. Skin dryness or peeling may persist throughout therapy, although these effects generally diminish during the course of treatment.

In acne treatments, skin irritation is directly related to the efficacy of tretinoin-based products and resolves when applications are spaced out.

Rarely, contact allergies have occurred with topical use of tretinoin.

There have been reports of temporary increases and decreases in pigmentation due to repeated application. Increased sensitivity to sunlight or other sources of UVB radiation has also been observed.

To date, all adverse effects associated with Retirides 1 mg/g cream have been reversible upon discontinuation of treatment.
