Ce este Aldara (Imiquimod)?
Aldara (imiquimod 5% cream) is a prescription topical medicine used to treat external genital and perianal warts caused by certain strains of the human papillomavirus (HPV). It is approved by the European Medicines Agency (EMA) and classified as an immune response modifier rather than a direct antiviral agent.
Unlike treatments that physically destroy wart tissue, Aldara works by engaging the body’s own immune system to target HPV-infected cells. This mechanism distinguishes it from other wart treatments such as podophyllotoxin (Condyline, Warticon) and cryotherapy.
Cum funcționează Aldara (Imiquimod)?
Imiquimod, the active ingredient in Aldara, acts as a toll-like receptor 7 (TLR7) agonist. When applied to wart tissue, it binds to immune cells in the skin and triggers a cascade of immune responses:
- Interferon production: Imiquimod stimulates the release of interferon-alpha and other cytokines, which activate the immune system’s antiviral response at the site of application.
- Cytokine cascade: The immune activation leads to local production of tumour necrosis factor-alpha (TNF-alpha) and interleukins, which promote immune cell infiltration into wart tissue.
- Cell-mediated immunity: T-lymphocytes are recruited to the treatment area, where they target and eliminate HPV-infected keratinocytes.
- Indirect antiviral effect: Because imiquimod acts on immune cells rather than directly on the virus, it does not kill HPV; instead, it helps the immune system clear infected tissue.
This immune-mediated mechanism explains why local skin reactions (redness, erosion, flaking) are both expected and indicative that the medicine is working.
Pentru cine este indicat Aldara (Imiquimod)?
Aldara is indicated for adults with external genital and perianal warts. It is not suitable for:
- Internal warts: Aldara is for external use only and should not be applied inside the vagina, urethra, or rectum.
- Children and adolescents: The safety and efficacy of imiquimod in patients under 18 years have not been established for this indication.
- Pregnant women: There is limited safety data for imiquimod in pregnancy. A doctor must carefully assess the risk-benefit balance.
- Patients with compromised immune systems: Imiquimod’s mechanism depends on an intact immune response; effectiveness may be reduced in significantly immunocompromised individuals.
A full medical assessment by a qualified independent doctor is required before any prescription is issued.
Dozaj și administrare
Aldara 5% cream is applied three times per week (for example, Monday, Wednesday, Friday) before normal sleeping hours, typically for a period of 6 to 16 weeks.
Application instructions (as per EMA-approved guidance):
- Wash the treatment area with mild soap and water and allow to dry.
- Apply a thin layer of Aldara cream to the warts and rub in gently until absorbed.
- Leave the cream on for 6 to 10 hours, then wash off with soap and water.
- Do not cover the treated area with an occlusive dressing.
- Avoid sexual contact while the cream is on the skin.
| Aspect | Detail |
|---|---|
| Application frequency | 3 times per week (non-consecutive days) |
| Maximum duration | 16 weeks |
| Cream per application | Up to 250 mg (one sachet or a small pump dose) |
| Wash-off time | 6–10 hours after application |
Treatment should be discontinued if severe local skin reactions occur, and resumed when the reaction has subsided. A doctor should be consulted if warts worsen or do not improve.
Efecte secundare
Aldara is associated with predictable local skin reactions, which reflect the immune activation at the treatment site.
Efecte secundare foarte frecvente (afectând mai mult de 1 din 10 persoane)
- Redness (erythema) at the application site
- Flaking or peeling of the skin
- Itching
- Burning or stinging sensation
Efecte secundare frecvente (afectând 1 până la 10 din 100 de persoane)
- Erosion or ulceration at the application site
- Swelling or oedema
- Induration (hardening of skin)
- Scabbing
Efecte mai puțin frecvente, dar notabile
- Flu-like symptoms (fatigue, headache, myalgia)
- Pigmentation changes at the treatment site (which may be persistent)
- Remote site skin reactions
Severe local reactions may require a treatment break. Patients should contact their doctor if they experience any reaction that concerns them.
Aldara (Imiquimod) vs alternative
Several treatment options are available for external genital warts in Europe. The choice between them depends on wart characteristics, patient preference, and clinical assessment by an independent doctor.
| Treatment | Active Ingredient | Mechanism | Application |
|---|---|---|---|
| Aldara | Imiquimod | Immune stimulation | 3x/week cream, up to 16 weeks |
| Condyline | Podophyllotoxin | Antimitotic (cell death) | Twice daily, 3 days on/4 days off |
| Warticon | Podophyllotoxin | Antimitotic (cell death) | Twice daily, 3 days on/4 days off |
| Cryotherapy | Liquid nitrogen | Physical destruction | Clinic-based procedure |
Aldara is generally preferred for larger or multiple wart areas where patient-applied treatment over several weeks is appropriate. Podophyllotoxin preparations may offer faster clearance of smaller lesions. All treatment decisions must be made by a qualified doctor.
Cum puteți obține Aldara (Imiquimod) online în Europa
Aldara este un medicament eliberat numai pe bază de prescripție medicală în toate statele membre ale UE. Nu poate fi eliberat legal fără o prescripție valabilă de la un medic autorizat.

Procesul este următorul:
- Completați un chestionar medical: Answer structured questions about your health history, current symptoms, and medications. Your responses are reviewed by an independent doctor.
- Evaluarea medicului: An independent EU-registered doctor reviews your assessment. If imiquimod is clinically appropriate, they may issue a prescription.
- Prescripție și livrare: If a prescription is issued, it is sent to a licensed EU pharmacy partner, which dispenses and ships the medicine directly to you.

Interacțiuni medicamentoase: Imiquimod is applied topically and systemic drug interactions are not well documented; however, avoid use with other topical products on the same area simultaneously unless directed by a doctor.
Aldara does not treat the underlying HPV infection and does not prevent transmission to sexual partners. Barrier contraception (condoms) reduces but does not eliminate the risk of HPV transmission.

Frequently asked questions
- Pentru ce se utilizează Aldara (Imiquimod)?
- Aldara (imiquimod 5% cream) is approved by the EMA for the topical treatment of external genital and perianal warts (condylomata acuminata) in adults. It is also used for certain types of superficial skin conditions including actinic keratoses and superficial basal cell carcinoma under medical supervision.
- Cum funcționează Aldara (Imiquimod)?
- Imiquimod is an immune response modifier. It does not act directly on the human papillomavirus (HPV) but instead stimulates the local immune system to produce interferons and other cytokines, which help the body recognise and eliminate HPV-infected cells. This immune-mediated response is what clears the visible warts.
- Cât timp does Aldara treatment take?
- Aldara is typically applied three times per week (not on consecutive days) for up to 16 weeks. Clinical trials show that visible wart clearance occurs in approximately 50-60% of patients within this period. A doctor will advise on the appropriate treatment duration based on your response.
- Pot obține Aldara (Imiquimod) online în Europa?
- Puteți accesa acest medicament prin platforme intermediare online care vă conectează cu medici independenți înregistrați în UE. După completarea unui chestionar medical confidențial, un medic va evalua dacă medicamentul este adecvat clinic pentru dumneavoastră.
- Care sunt cele mai frecvente efecte secundare?
- Local skin reactions are the most common side effects: redness, flaking, swelling, erosion, and itching at the application site. These reactions indicate the immune response is active and are generally expected. Systemic side effects are uncommon but may include fatigue, headache, and flu-like symptoms. Severe reactions should be reported to a doctor.
