Frequently asked questions
AGOVIRAX® is a medical device for the prevention and supportive treatment of viral upper respiratory tract infections. AGOVIRAX® is available in two forms: AGOVIRAX® nasal spray and AGOVIRAX® lozenges.
AGOVIRAX® helps protect against viral upper respiratory tract infections (reduces the amount of viruses in the nasopharyngeal mucosa by up to 92%¹), including COVID-19 (reduces the risk of contracting COVID-19 by up to 80%²).
The iota-carrageenan in AGOVIRAX® forms a protective layer that prevents viruses from attaching, thus reducing their replication and spread. Detailed information about AGOVIRAX®’s mechanism of action can be found in the “About AGOVIRAX®” section on our website.
Scientific studies show that to achieve the same virus-inhibiting effect, iota-carrageenan requires 10 times lower concentration than kappa or lambda carrageenans. This makes iota-carrageenan more effective in protecting against common cold viruses.¹²
A single spray protects against common cold viruses for up to 3 hours.
AGOVIRAX® works immediately, and its effect lasts up to 3 hours. Therefore, in situations with an increased risk of virus exposure, regular use of AGOVIRAX® is recommended.
To reduce the risk of catching cold viruses, AGOVIRAX® is recommended in high-risk situations, such as crowded places, schools, medical facilities, and during travel. It can also be used at the first signs of a cold (sneezing, sore throat, runny nose).
AGOVIRAX® can be used regularly as needed, as it poses no risk of dependence or overdose.
Standard usage for nasal spray: at the first signs of a common cold (e.g., sore throat, tingling, runny nose), spray once into each nostril at least 3 times a day.
Standard usage for lozenges: use several times a day, typically 3–6 times, depending on individual needs. Do not exceed six lozenges per day to avoid a possible laxative effect.
