What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Lumigan, also known by its generic name Bimatoprost, is an FDA-approved prescription medication developed by Allergan, Inc. Initially, it was introduced as a glaucoma treatment, but its side effects sparked interest in another cosmetic use – enhancing eyelash growth. The active ingredient, Bimatoprost, belongs to the prostaglandin analogs class, which helps in reducing intraocular pressure (IOP) and extending the growth phase of eyelashes.
Lumigan works by increasing the outflow of aqueous humor, the clear fluid inside the eyes, which helps to lower IOP. It achieves this by mimicking the effects of prostamides, natural chemicals found in the body that regulate eye pressure. By enhancing the drainage of fluid from the eyes, Lumigan effectively reduces the risk of optic nerve damage and preserves vision.
Individuals diagnosed with open-angle glaucoma, closed-angle glaucoma, or normal-tension glaucoma can benefit significantly from Lumigan. It helps in reducing IOP and preventing the progression of the disease, safeguarding their vision. People with ocular hypertension, even without glaucoma, may receive Lumigan prescriptions to lower their IOP and decrease the risk of developing glaucoma in the future. In some cases, healthcare professionals may prescribe Lumigan off-label for certain eyelash growth treatments, known as “Latisse.” The active ingredient Bimatoprost is also used in Latisse to enhance eyelash growth.

Initial Dosing of Lumigan
The initial dosing of Lumigan is crucial for patients starting their glaucoma or ocular hypertension treatment journey. Typically, the recommended dosage is one drop of Lumigan 0.01% or 0.03% in the affected eye(s) once daily, preferably in the evening. The concentration prescribed by the healthcare professional may vary based on the severity of the condition and individual patient factors.
Maintenance Dosing of Lumigan
Once the initial dosing period has passed, patients will transition to the maintenance dosing phase. During this phase, the goal is to maintain stable IOP levels while keeping side effects at a minimum. The maintenance dosage is similar to the initial dose – one drop of Lumigan 0.01% or 0.03% in the affected eye(s) once daily in the evening.
If patients are uncertain about what to do after missing a dose, they should contact their healthcare provider for guidance. In the event of a missed dose, patients should take the following steps:
- If the missed dose is noticed within a short time after the regular dosing time, the patient should instill the eye drop immediately.
- If it is close to the next scheduled dose, the missed dose should be skipped, and the patient should resume regular dosing the next day.
- Patients should never double the dose to make up for a missed one, as this may lead to adverse effects.
An overdose of Lumigan can be hazardous and should be avoided at all costs. If someone accidentally ingests Lumigan or uses more than the prescribed dose in the eyes, they should seek immediate medical attention.
Symptoms of Lumigan overdose may include severe eye irritation, eye redness, eye pain, excessive tearing, headache, dizziness, and vision changes. Emergency medical treatment can help mitigate the effects of an overdose and prevent any potential complications.
