Cold Sore Treatment in Spain: Without a Prescription?
In Spain, the cream sold as Zovirax and all antiviral tablets (aciclovir, valaciclovir) need a prescription. Non-prescription Zovicrem Labial exists.

What should you do if you get a cold sore in Spain?
Quick answer: You can buy certain cold sore creams directly from a Spanish pharmacy without a prescription, but all oral antiviral tablets (such as aciclovir, valaciclovir, or famciclovir) require a medical prescription by law. The cream sold under the brand name Zovirax is prescription-only in Spain, while non-prescription creams are sold under other names like Zovicrem Labial or Fenivir.
If you need a prescription cold sore medication, an online cold sore consultation with UrgentDoc allows you to consult a licensed doctor via video. Our doctors review your symptoms, medical history, allergies, and current medications to determine if prescription treatment is appropriate. If the doctor decides a medicine is appropriate, you receive a private electronic prescription as a PDF by email, issued through a private e-prescription platform such as REMPe. Show the PDF at a pharmacy; the pharmacist checks it before dispensing it.

Which cold sore treatments can you buy without a prescription in Spain?
Under Spanish law, medicines may only be dispensed by authorised pharmacies (BOE Real Decreto Legislativo 1/2015). Spain classifies each medicine product, not each ingredient, as prescription-only or non-prescription, so two creams with the same 5% aciclovir can have a different status (AEMPS CIMA; BOE Real Decreto Legislativo 1/2015).
The following table details the legal dispensing status, product classifications, and official label indications for cold sore treatments marketed in Spain according to the Spanish medicines agency database (AEMPS CIMA):
| Product (Spanish name) | Active ingredient | Prescription? | Who the label covers | What the label says about use |
|---|---|---|---|---|
| Zovicrem Labial crema | aciclovir 5% | No | adults and 12+ | at first symptoms, 5 times a day, at least 4 days, up to 10 (AEMPS CIMA) |

| Lavirk gel | aciclovir 5% | No | recurrent cold sores; children 2-12 only on medical recommendation | at least 4 days, see a doctor if still present after 10 (AEMPS CIMA) |
| Zoviduo crema | aciclovir 5% + hydrocortisone 1% | No | immunocompetent adults and 12+, recurrent cold sores | 5 times a day for 5 days (AEMPS CIMA) |

Is Zovirax the same in Spain? What cold sore creams are called
In Spain, the cream sold as Zovirax needs a prescription; the non-prescription aciclovir cold sore products are sold under other names, such as Zovicrem Labial (AEMPS CIMA). Prescription-only Zovirax cream has a broader licence in Spain, covering localised skin herpes simplex infections including cold sores and initial or recurrent genital herpes (AEMPS CIMA). In Spanish, a cold sore is commonly called a calentura or herpes labial (AEMPS CIMA; AEMPS CIMA).
Non-prescription lip products are indicated strictly for the lips and surrounding facial skin; they must not be used on mucous membranes or for genital herpes (AEMPS CIMA). If you have questions about intimate symptoms, you can book a sexual health consultation online.
| Name you may know | What it is in Spain | Prescription? |
|---|---|---|
| Zovirax cream | aciclovir in Spanish pharmacies (Zovirax 50 mg/g crema) | Yes |
| Aciclovir 5% cream (generic) | 'Aciclovir [maker] 50 mg/g crema EFG' | Yes |
| Non-prescription aciclovir lip cream | Zovicrem Labial / Viruderm / Lavirk | No |
| Aciclovir + hydrocortisone cream | Zoviduo | No |
| Penciclovir cream | Fenivir | No |
| Valaciclovir | Valtrex or valaciclovir EFG | Yes |
| Famciclovir | Famvir or famciclovir EFG | Yes |
Can you buy aciclovir or valaciclovir tablets over the counter in Spain?
No oral antiviral tablets can be purchased over the counter in Spain. Every tablet formulation containing aciclovir, valaciclovir, or famciclovir is classified as a prescription-only medicine by the Spanish medicines agency (AEMPS CIMA).
Spanish pharmacies are prohibited by law from selling prescription-only medicines over the counter or online (BOE Real Decreto Legislativo 1/2015). Oral antivirals are indicated for systemic treatment, and the prescribing doctor must determine the appropriate drug and dosage while checking your medical history. For instance, Valtrex (valaciclovir) dose requirements must be adjusted if kidney function is reduced (AEMPS CIMA).
When do you need prescription cold sore medicine?
While topical lip creams are accessible directly from a pharmacist, several clinical circumstances require a doctor's assessment and prescription:
- Severely weakened immune system: Patients who are immunocompromised (such as those with advanced HIV, bone marrow transplants, or receiving chemotherapy or radiotherapy) must consult a doctor before using topical cold sore products, as herpes can present with more severe symptoms (AEMPS CIMA; AEMPS CIMA; WHO).
- First outbreak or young children: A first outbreak requires a medical diagnosis, particularly in children where symptoms can be mistaken for teething issues or other oral conditions (AEMPS CIMA). Non-prescription lip creams are not approved for children under 12 without medical advice (AEMPS CIMA; AEMPS CIMA).
- No improvement or worsening: If the lesion worsens or fails to heal after 10 days of topical treatment, you must stop use and consult a doctor (AEMPS CIMA).
- Pregnancy and breastfeeding: Pregnant or breastfeeding women should consult a medical doctor before using non-prescription cold sore creams (AEMPS CIMA).
- Frequent recurrences: Aciclovir tablets are licensed for preventing recurrent herpes simplex infections in people with a normal immune system (AEMPS CIMA). The World Health Organization notes that taking a daily antiviral medicine (suppressive therapy) can decrease how often symptoms occur (WHO). A doctor can evaluate your medical history to discuss whether daily suppressive therapy is clinically appropriate.
How do you get a cold sore prescription online in Spain?
If you require systemic medication or a clinical assessment, you can schedule a same-day online cold sore consultation with UrgentDoc. You select an appointment time offered by our licensed doctors.
During the video consultation, the doctor examines the visual presentation of your lesion and discusses your medical background, including any kidney conditions or concurrent medications. A prescription is never guaranteed; it remains entirely at the doctor's clinical discretion.
If the doctor decides a medicine is appropriate, you receive a private electronic prescription as a PDF by email, issued through a private e-prescription platform such as REMPe. Show the PDF at a pharmacy; the pharmacist checks it before dispensing it. Medicines are paid for separately at the pharmacy counter. UrgentDoc also provides an invoice that you can submit to your travel insurer for consideration.
By Spanish law, a private medical prescription must include the patient's DNI, NIE, or passport number, the doctor's full name, contact information with international dialling codes, professional address including town and "Spain", medical qualification, professional college registration number (número de colegiado), and an electronic signature (BOE Real Decreto 1718/2010). By rule, prescriptions state the active pharmaceutical ingredient rather than commercial brand names (BOE Real Decreto 1718/2010).
Will a Spanish pharmacy accept a UK prescription for valaciclovir?
Spain's rule for prescriptions from other EU countries does not cover UK or US prescriptions, so you need a Spanish one. Spanish law allows community pharmacists to dispense prescriptions issued in another EU Member State for authorised medicines, provided the authenticity can be verified (BOE Real Decreto 1718/2010). Because the UK is no longer an EU member, Spanish pharmacists are not legally required to honour British paper or digital prescriptions.
If you are living in Spain or travelling long-term and need continuous treatment, you can secure repeat prescriptions for UK expats in Spain. Patients requiring long-term preventive suppressive therapy who have exhausted their supply can also consult a doctor for a repeat prescription online. If you have misplaced your usual travel supply, read our guide on what to do if you lose your medication in Spain.
How do you stop a cold sore spreading on holiday?
Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which the World Health Organization estimates infects 3.8 billion people under age 50 globally (WHO). Outbreaks on holiday are commonly triggered by factors such as sunburn, travel anxiety, fever, colds, or fatigue (AEMPS CIMA).
The typical cycle begins with a tingling, itching, or stinging sensation on the lip, followed within one to two days by small blisters that burst into open sores before crusting over (AEMPS CIMA). Cold sores remain contagious until a crust has fully formed (AEMPS CIMA).
To prevent spreading the infection to other people or other areas of your body:
- Wash your hands thoroughly after applying any cream (AEMPS CIMA).
- Avoid letting the lip lesion touch other parts of your body or other individuals, especially babies and young children (AEMPS CIMA).
- Do not share bath towels, and use disposable paper tissues to avoid reinfecting yourself (AEMPS CIMA).
- Avoid oral contact with others, including kissing and oral sex, while symptoms are active (WHO).
- Do not share items that have been in contact with saliva, such as cutlery, cups, or lip balms (WHO).
Topical non-prescription creams provide local symptomatic relief but do not prevent future outbreaks (AEMPS CIMA; AEMPS CIMA).
When should you seek urgent or in-person care?
Certain symptoms present medical risks that cannot be managed via telemedicine or over-the-counter creams:
- Eye involvement: Any tingling, blister, redness, or pain near the eye, or changes such as blurred vision, requires immediate in-person medical evaluation. HSV can cause keratitis, an infection of the eye (WHO). If cold sore cream accidentally enters the eye, rinse immediately with plenty of water and seek in-person medical care (AEMPS CIMA). A video consultation cannot examine the eye.
- Signs of severe systemic infection: In rare cases, HSV-1 can lead to severe central nervous system complications such as encephalitis (brain infection) (WHO). If a patient develops confusion, a seizure, unusual drowsiness, or becomes suddenly very unwell, call 112 immediately.
- Infants and young babies: Keep lesions away from babies' skin (AEMPS CIMA). If a baby develops blisters or seems unwell, arrange an in-person medical assessment.
- Compromised immunity: People with advanced HIV, organ transplants, or active cancer therapy should see a doctor promptly rather than self-treating (AEMPS CIMA; WHO).
- Non-healing or spreading sores: If the sore worsens or fails to heal after 10 days of cream application, stop use and be seen in person (AEMPS CIMA).
Frequently Asked Questions
Can you buy Zovirax over the counter in Spain?
No. In Spain, the cream sold under the brand name Zovirax is classified as a prescription-only medicine (AEMPS CIMA). If you want an over-the-counter aciclovir cream for your lips, you must ask the pharmacist for non-prescription options such as Zovicrem Labial, Viruderm, or Lavirk (AEMPS CIMA).
Can you buy aciclovir tablets over the counter in Spain?
No. All oral antiviral medications, including aciclovir, valaciclovir, and famciclovir tablets, require a medical prescription in Spain (AEMPS CIMA). Spanish pharmacies are barred by law from dispensing oral antivirals without a valid prescription from a doctor (BOE Real Decreto Legislativo 1/2015).
What is a cold sore called in Spanish?
A cold sore is most commonly referred to as a calentura or herpes labial in Spain (AEMPS CIMA; AEMPS CIMA). If speaking to a pharmacist, asking for a product for a calentura en el labio will help them locate non-prescription treatments like Zovicrem Labial (AEMPS CIMA).
Can I use my UK prescription for valaciclovir in Spain?
Spain's rule for prescriptions from other EU countries does not cover UK or US prescriptions, so you need a Spanish one (BOE Real Decreto 1718/2010). Pharmacists in Spain are under no obligation to recognise UK prescriptions following Brexit. You must have a doctor licensed in Spain evaluate your case and issue a compliant Spanish prescription.
Can I buy cold sore tablets online from a Spanish pharmacy?
No. Spanish law strictly prohibits the online or mail-order sale of prescription-only medications (BOE Real Decreto Legislativo 1/2015). While licensed pharmacies can sell non-prescription lip products, oral antiviral tablets must be dispensed in person following the presentation of a valid prescription (BOE Real Decreto Legislativo 1/2015).
Is there a cure for cold sores?
No. There is currently no cure that eliminates the herpes simplex virus from the body (WHO). Antiviral medications can decrease how long symptoms last and how severe they are, and daily suppressive therapy can decrease how often outbreaks occur, but they do not eradicate the infection (WHO).
Can I get cold sore treatment online in Spain?
Yes. You can consult a licensed doctor via telemedicine who can clinically assess your outbreak. If the doctor determines that an antiviral medicine is appropriate, they will issue a Spanish private electronic prescription that you can collect at a local pharmacy.
