Carbomer
Uses of Carbomer
Carbomer is primarily used as a stabilizing and suspending agent in various pharmaceutical formulations, including ophthalmic formulations for the management of dry eyes and other ocular conditions. It belongs to the class of artificial polymers.
In addition to this primary use, Carbomer is also employed in topical drug delivery systems such as gels, creams, and ointments to enhance viscosity and improve contact time with the skin or mucous membranes, thus enabling better medicine absorption. It is also used in oral mucoadhesive drug delivery systems and in developing controlled release drug delivery systems.
Side effects of Carbomer
Eye irritation or discomfort
Redness of the eyes
Skin irritation or rash
Gastrointestinal discomfort
How Carbomer works
Carbomer is a high molecular weight polymer that is commonly used in pharmaceutical formulations.
It exhibits strong mucoadhesive properties due to its high molecular weight and numerous carboxylic acid groups. As a result, it forms hydrogen bonds and electrostatic interactions with the mucous layer, enhancing the retention of the medication at the site of application.
Carbomer also acts as a thickening agent, increasing the viscosity of the formulation. This property helps to prolong the contact time of the medication with the biological surface, improving medicine absorption and efficacy.
In addition, Carbomer stabilizes suspensions and emulsions by forming a three-dimensional network that prevents particle settling and phase separation. This ensures the homogeneity and stability of the formulation.

Expert Advice
Dosage Forms Available
Carbomer is available in a variety of formulations including eye drops and gels for treating dry eyes and other ocular conditions.
It is used topically in the form of gels, creams, and ointments for dermatological applications.
Carbomer is also available in oral formulations, which are taken orally as part of 'mucoadhesive drug delivery systems'.
Age and Dose Restrictions
This medicine is generally suitable for adults and children, though the specific age range may depend on the formulation type and the condition being managed.
Always follow your doctor's instructions regarding the age appropriateness and dosage of this medicine.
Contraindications
Patients with known allergies to Carbomer or any of its excipients should avoid using products containing this polymer.
Individuals with severe ocular surface disorders or corneal epithelial defects should not use Carbomer-based eye drops without consulting an ophthalmologist.
Other Medications to Avoid
Although no significant interactions between Carbomer and other medications have been reported, it is crucial to consult a doctor before starting any new prescription or over-the-counter medications while using products that contain Carbomer.
Overdose and Missed Dose
Overdosing on Carbomer-based products can lead to discomfort or complications depending on the route of administration (ocular, topical, oral). Consult your doctor promptly if you suspect an overdose.
If you miss a dose, take it as soon as you remember. However, do not double up on doses to make up for the missed one.
Management of Side Effects
Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor.
If you experience eye irritation, redness, or discomfort after using Carbomer eye drops or gels, discontinue use and consult an ophthalmologist.
In case of skin irritation or rash following the application of topical Carbomer formulations, stop using the product and seek medical advice.
For gastrointestinal discomfort from oral Carbomer formulations, drinking plenty of water may help. If the discomfort persists, consult your doctor.
Use in Driving and Operating Machinery
Products containing Carbomer do not typically affect your ability to drive or operate heavy machinery. However, if you experience any dizziness or vision changes after application (particularly relevant for ocular formulations), refrain from these activities until the symptoms subside.
Use in Pregnancy and Lactation
There is limited data on the safety of Carbomer during pregnancy and breastfeeding. Therefore, it is recommended to consult your doctor before using Carbomer-based products during these periods.
Caution in Other Conditions
No specific conditions have been flagged where caution needs to be taken while using Carbomer. However, it's important to consult a doctor if you have any ongoing health conditions prior to starting any new medication.
Special Dietary and Lifestyle Recommendations
To manage dry eye symptoms, consider eating a diet rich in omega-3 fatty acids which can help improve overall eye health.
Regularly clean your eyelids with a warm washcloth to remove debris and reduce symptoms of dry eyes.
For skin conditions, maintain a regular skincare routine that includes gentle cleansing and moisturizing. Avoid harsh soaps or skincare products that could exacerbate irritation.
Frequently asked questions
Is Carbomer a natural or synthetic compound?
Carbomer is a synthetic, high molecular weight polymer of acrylic acid. It is not a natural substance but is produced in laboratories for use in various pharmaceutical formulations and cosmetic products.
Can Carbomer cause allergies?
While Carbomer is generally safe and well-tolerated, there have been rare cases of individuals, with known hypersensitivity to the polymer, experiencing allergic reactions. If you have a known allergy to any of the ingredients in a Carbomer-based product, it is advised that you avoid its use.
Does Carbomer affect the absorption of other medicines?
Carbomer acts as a thickening agent, enhancing the viscosity of the formulation and improving the contact time of the medication with the biological surface. This property can lead to improved absorption and efficacy of the medicine.
Is it safe to use cosmetic products containing Carbomer?
Yes, Carbomer is widely used in various cosmetic products due to its stabilizing and viscosity-enhancing properties. However, as with any product applied to the skin, it is always sensible to perform a patch test first to check for any potential reactions.
How does Carbomer work in dry eye treatments?
In ophthalmic formulations, Carbomer functions as a stabilizing and suspending agent. It helps lubricate and protect the eye surface, providing relief from uncomfortable symptoms like burning sensations and discomfort associated with dry eyes.
Can Carbomer be used in oral drug delivery systems?
Yes, Carbomer is used in oral mucoadhesive drug delivery systems due to its excellent bioadhesive properties. It prolongs the residence time of the medication in the gastrointestinal tract, leading to improved bioavailability and therapeutic efficacy.
How should I store my Carbomer-based medication?
Always store your Carbomer-based medication as advised on the product label or as directed by your doctor. Typically, it should be stored at room temperature, away from heat and moisture.
