Careprost (Bimatoprost) – Patient Information (Australia)

Careprost is a brand of bimatoprost, a medicine used to lower increased eye pressure and to improve the appearance of eyelashes. This page explains how Careprost works, how to use it safely, and what to expect. It is written for patients in Australia and covers practical use, interactions, safety, and common questions.

Key Points at a Glance

• What it is: Bimatoprost eye drops (usually a clear, colourless solution).
• Main uses: Management of glaucoma or ocular hypertension, and for eyelash growth in eligible patients.
• How it works: Helps the eye drain fluid more effectively and may increase eyelash length/thickness.
• How to use: Typically once daily in the evening (at the same time each day).
• Common side effects: Redness, itching, dry eye, darkening of eyelids, and eyelash changes.
• Important: Avoid contaminating the dropper tip and use carefully to prevent spread to the other eye or skin.

Basic Product Information

Note: Always check your pack for the exact strength, dosing schedule, expiry date, and storage instructions.

How Careprost Works (Mechanism of Action)

1) Lowering eye pressure

In glaucoma and ocular hypertension, the eye produces fluid (aqueous humour) and normally drains it through specific drainage pathways. When drainage is reduced, intraocular pressure (IOP) can rise, which may damage the optic nerve.

Bimatoprost is a prostaglandin-related medicine. It helps increase outflow of fluid from the eye, thereby reducing intraocular pressure. By lowering IOP, it helps reduce the risk of vision loss associated with glaucoma.

2) Improving eyelash appearance

In some patients, bimatoprost can lengthen, thicken, and darken eyelashes and increase the number of lashes in the growth phase. This effect is related to changes in eyelash follicles over time.

Pharmacokinetics (What the Body Does to the Medicine)

Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a drug.

• Absorption: After eye drop application, bimatoprost is absorbed through the ocular tissues. Systemic absorption is generally low when used correctly.
• Distribution: The medicine can reach ocular tissues where it exerts its effects. Some drug may enter the bloodstream.
• Metabolism: Bimatoprost is processed in the body mainly by metabolic pathways that can include enzymatic conversion.
• Elimination: Metabolites are removed primarily via renal (kidney) and hepatic (liver) processes. The overall systemic exposure is typically limited for ophthalmic use.

Practical implication: Because most of the effect is local to the eye, many people experience eye-related side effects rather than whole-body effects. Nonetheless, it’s still important to follow dosing and precautions, especially if you have other medical conditions.

Typical Use and Indications

Glaucoma and ocular hypertension

Careprost is used to help lower increased intraocular pressure in:

• Open-angle glaucoma
• Ocular hypertension (increased eye pressure without diagnosed glaucoma)

Eyelash growth

Some formulations of bimatoprost are used to enhance the appearance of eyelashes in patients with specific eligibility criteria. Results are gradual and dependent on consistent use.

Important: Only use Careprost for the purpose described in your product information and under Australian medical guidance where applicable.

How and When to Use Careprost

General dosing pattern

For most patients, bimatoprost eye drops are used as:

• Once daily
• In the evening (commonly before going to bed)

Why evening timing matters

Bimatoprost often performs best with consistent daily dosing and is typically scheduled for the evening. This is due to the way the body and eye regulate aqueous humour and the drug’s time-dependent effect.

Tip: Choose an evening time that you can maintain daily (e.g., 9 pm) to keep drug exposure steady.

Step-by-step practical instructions

1. Wash your hands before using the drops.
2. If using for the eye affected by glaucoma/pressure or eyelash growth, tilt your head back and gently pull down the lower eyelid.
3. Hold the bottle above the eye and apply one drop into the lower eyelid area.
4. Avoid touching the eye or eyelids with the bottle tip.
5. Close your eye and gently press a finger on the inner corner of the eye (near the nose) for about 1–2 minutes. This can help reduce drainage into the rest of the body.
6. Wipe away excess liquid from the eyelid with a clean tissue.
7. Replace the cap tightly and store as directed.

If you miss a dose

• If you remember later the same night, use the dose if it’s close to your usual timing.
• If it’s almost time for the next dose, skip the missed dose and continue your regular schedule.
• Do not use a double dose to make up for a missed one.

If you use other eye drops

Many glaucoma patients use multiple treatments. A common rule is to separate drops:

• Use bimatoprost as directed.
• If you must use other eye drops, separate them by at least 5–10 minutes to prevent washing away the previous drop.
• Use the sequence recommended by your eye care professional or pharmacy label (often medicated drops first, lubricating drops last, unless told otherwise).

Food Interactions

Because Careprost is applied to the eye, food interactions are not expected to be significant. The medicine is delivered locally to ocular tissues, and systemic absorption is generally limited when used correctly.

That said, if you experience side effects such as light-headedness or headache, note that other factors (including dehydration or missed meals) may contribute. If you have concerns, speak with your pharmacist or prescriber.

Alcohol and Medicine Interactions

Alcohol

There is no strong reason to expect a direct interaction between alcohol and bimatoprost eye drops. However:

• Alcohol may worsen dry eye symptoms in some people.
• Alcohol can increase irritation or worsen sensitivity for some patients.
• If you feel unwell after use, avoid alcohol and seek advice.

Interactions with other medicines

Ophthalmic medicines can interact indirectly (for example, by affecting eye irritation or by compounding dryness). Direct pharmacological interactions are less likely with eye drops than with tablets, but it’s still important to review your medication list.

Tell your healthcare provider if you use:

• Other glaucoma medicines (e.g., beta-blocker drops, carbonic anhydrase inhibitor drops, alpha agonists)
• Any drops containing preservatives if you have sensitivity
• Medicines that affect the body’s metabolism (always confirm with a clinician if you take complex regimens)

Practical caution: Do not start, stop, or change glaucoma medications without advice. If you experience new or worsening symptoms, review your full eye-care routine.

Safety Profile (Side Effects and When to Seek Help)

Common side effects

Many side effects are mild and improve as your eyes adapt. Possible effects include:

• Eye redness
• Itching or irritation
• Dry eye sensation
• Watery eyes
• Temporary blurred vision right after application (avoid driving until clear)
• Change in eyelash appearance (lengthening, darkening, increased thickness)
• Darkening of the eyelid skin or changes around the eye

Less common but important effects

• Eye discomfort that persists or worsens
• Swelling of eyelids
• Light sensitivity
• Changes in iris colour (more likely with long-term use and in some eye colours)
• Headache or dizziness (uncommon, but possible)

Serious symptoms: seek urgent advice

Contact an eye doctor or seek urgent medical care if you develop:

• Severe eye pain
• Marked redness with worsening symptoms
• Significant vision changes (persistent or rapidly worsening)
• Severe light sensitivity
• Signs of allergy (swelling of face/eyes, hives, difficulty breathing)

Safety tips to reduce risk

• Use only the prescribed/labelled number of drops.
• Keep your drop tip clean—never touch it to your eye.
• Wash hands before and after use.
• Remove contact lenses before instillation (see below).

Practical Use Tips (Often Overlooked)

Contact lenses

Many eye-drop instructions advise removing contact lenses before using bimatoprost and waiting before reinsertion. Follow your product label or ask your pharmacist. A common approach is:

• Remove lenses before drops.
• Wait a suitable interval (often around 15 minutes) before putting lenses back.

Reason: Some drops may contain ingredients that can interact with lens materials or increase irritation.

Preventing spread to skin

Bimatoprost can cause darkening of skin and changes around the application site. To reduce this:

• Apply carefully to the eye (not the skin beyond the lower eyelid).
• Wipe any overflow immediately.
• Wash hands after application.

Managing dryness and irritation

• Use lubricating eye drops if recommended and separate them from bimatoprost by 5–10 minutes.
• Avoid eye rubbing.
• If you wear makeup, consider pausing until symptoms settle.

Driving and operating machinery

Some people experience brief blur after instillation. Wait until vision is clear before driving or operating machinery.

Dosing Guidance (Patient-friendly)

Typical adult dosing (confirm your exact product instructions):

• Once daily in the evening.
• Apply one drop to the affected eye(s) unless your clinician instructs otherwise.

Do not increase frequency to try to speed results. Overuse can increase the risk of side effects and may not provide additional benefit.

Special considerations: Dosing and suitability may differ for children, people with specific eye conditions, or those using multiple eye medications—follow professional advice and your product label.

Alternative Options

For glaucoma and ocular hypertension

Alternative treatments your eye specialist may consider (depending on your condition) include:

• Other prostaglandin analogs (often similar effect profile)
• Beta-blocker eye drops
• Alpha-agonist eye drops
• Carbonic anhydrase inhibitor eye drops
• Combination drops (two medicines in one bottle)

For eyelash enhancement

Alternatives may include:

• Non-medicinal eyelash products (serums, conditioners, or cosmetic options)
• Other medically approved eyelash growth treatments if available and appropriate

Important: Discuss options with an eye care professional. The right choice depends on your eye health, previous treatments, and side-effect tolerance.
