Health officials urgently have recalled more than 11,000 eye drops due to production problems that the products have made possible that the patients could leave blindly.
British drugs Waakhond The Medicines and Healthcare Products Regulatory Agency (MHRA) made a warning on one batch of Zadites 0.25 mg/ml of eye drops, used to treat seasonal allergies such as hay fever.
It is feared that the drug may be contaminated during production, causing conjunctivitis and inflammation of the cornea and the eyelid possible.
Left untreated, these circumstances can cause permanent eye damage and even blindness.
Bacterial conjunctivitis – more generally known as a pink eye – is extremely contagious.
The infection usually influences both eyes and makes them red, itching and watery and often causes a sandy burning sensation.
In the most serious cases this can lead to the melting and perforation of the cornea and ultimately loss of eyesight if it is not treated immediately with antibiotics.
But the MHRA, who published the alert today, said that it had not yet received complication or reports from damage to patients who had taken the generally prescribed eye drops.
The eye drops work by suppressing the immune system and dampening the experience of the allergic reactions, but this specific batch may cause inflammation and serious infections, resulting in loss of vision
The recall has only a batch of the 5 ml eye drop solution, made by Laboratoires Théa, with the batch number 4V64 and an expiration date of 30 September 2026.
The eye drops are often prescribed to patients with hay fever to help manage seasonal symptoms such as red, itchy, watery and swollen eyes.
The drops can be taken by everyone older than three times a day.
The recall comes at a time when more people probably use eye drops, because the UK experiences high pollen rails, making seasonal conjunctivitis symptoms worse.
The eye drops work by prohibiting the release of natural substances, including histamine, in the body that cause allergic reactions.
Environmental monitoring plays a crucial role in developing sterile medicines, such as eye drops, so that manufacturers can gain insight into the presence of contaminants in the environment where the medicine is processed.
This helps to ensure that life -threatening bacteria may not come into contact with the medicine.
In his recall, the MHRA said that patients who experience side effects or have questions about the recall should have to seek medical help.

The recall comes in the midst of predictions of high pollen levels in the United Kingdom this month
Side effects must also be reported via the yellow card schedule of the MHRA.
The scheme, set up in the 1960s, enables doctors, pharmacists and patients to report side effects caused by recipe and freely available medicines, implants and alternative medicines.
This can lead to them being assessed, warnings have added to the label or even removed from the market.
Medical professionals have long insisted on the millions of Britons who suffer from poor hay fever and seasonal allergies to take precautions, including taking regular medication.
Patients are advised to visit their local pharmacy for fast and safe treatments to relieve their symptoms – with Zadites as a solution for recipe.
The NHS also recommends that people put Vaseline around their nostrils to keep pollen from the fall, wear a wrap-Around sunglasses to prevent pollen from getting in the eyes and showering and changing clothes after they have been outside to wash out pollen.
In contrast to a cold, which normally disappears within a week, hay fever can take weeks or months.
Symptoms start when immune cells wrongly identify pollen proteins as a threat and antibodies that cause chemicals that are called histamine.
These let the blood vessels dilate, causing the release of liquid from capillaries, causing a runny nose, sneezing and crying eyes.
Although they themselves are not life threatening, tens of thousands of patients with hay fever also have asthma, who can flare during pollen bombs. Asthma attacks can be fatal.
