Pilocarpine
About Pilocarpine
Pilocarpine is a prescription ophthalmic solution used to lower high pressure inside the eyes. It is primarily prescribed for people with open-angle glaucoma or ocular hypertension, conditions that can damage the optic nerves if left untreated. It may also be used to constrict the pupil before or after certain eye procedures.
To get the best results, you must use Pilocarpine consistently every day exactly as prescribed by your doctor. Since these are eye drops, they can be used without regard to meals, but establishing a regular daily schedule helps you remember your doses. Incorporating a heart-healthy diet, staying active, and reducing caffeine intake can also support your overall eye health.
While using Pilocarpine, you may experience temporary side effects like mild brow ache, headache, or blurry vision, especially in dim light. If you notice severe symptoms such as sudden changes in your vision, flashes of light, or signs of an allergic reaction, contact your doctor immediately.
Do not use Pilocarpine if you have active eye inflammation, such as iritis or uveitis, where pupil constriction should be avoided. Before starting this medication, tell your doctor if you have a history of retinal problems, asthma, or heart conditions.
Inform your doctor of all other eye medications you use, as some drops can counteract Pilocarpine or increase your risk of side effects. If you are pregnant, breastfeeding, or an older adult, consult your healthcare provider to ensure this treatment is safe for you.

Habit Forming
Diet & Lifestyle Advise
- Sleep with your head raised: Keep your head elevated slightly with an extra pillow while sleeping to help reduce eye pressure overnight.
- Limit caffeine: Limit your intake of caffeine, as drinking large amounts of caffeinated beverages in a short period can temporarily raise pressure inside your eyes.
- Stay physically active: Engage in moderate, regular exercise like walking, which may help lower eye pressure, but avoid exercises that involve head-down positions (such as certain yoga poses).
- Protect your eyes: Protect your eyes from bright light and injury by wearing sunglasses when outdoors, especially since your pupils may react differently to light while using this medication.
Special Advise
- Do not wear contact lenses before using Pilocarpine for at least 10 minutes after using Pilocarpine.
- If you have had any eye disorders, your doctor may perform an eye examination before using Pilocarpine and during the treatment.
- Let your doctor know that you are taking Pilocarpine before undergoing any operation or surgery, as this medicine may interact with medications used during anaesthesia.
- Pilocarpine should be used only in the infected eye, and contact with the normal eye should be avoided.
Patients Concern
Disease/Condition Glossary
Ocular hypertension: Ocular hypertension is a condition in which the eye's pressure is higher than normal due to poor drainage of the aqueous humour (fluid inside the eye). Essentially, this means that too much fluid enters the eye without being drained, causing high amounts of pressure to build up. The increased pressure can be due to certain other diseases, an injury, or an adverse effect of certain medications. If left untreated, it can lead to optic nerve damage and permanent vision loss.
Glaucoma: Glaucoma is an eye condition that causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. If it is not treated in time, it may cause blindness. Usually, there are no symptoms of glaucoma initially except for the slow loss of vision. However, some symptoms include visible rainbow-coloured circles around bright lights or blurred vision. Rarely, glaucoma can develop suddenly with intense pain in the eye, visual disturbance, or nausea.
FAQs
Pilocarpine is used to reduce elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. It is used to manage acute angle-closure glaucoma, the prevention of postoperative elevated IOP associated with laser surgery, and the induction of miosis (excessive constriction of the pupil of the eye).
Pilocarpine contains Pilocarpine. It reduces the eye's fluid production and increases the natural flow of fluid from inside the eye into the bloodstream. These effects help to decrease the pressure and swelling inside the eye. It helps to improve vision and prevent the complications of open-angle glaucoma or ocular hypertension.
Yes. If you are using more than one eye medication, wait at least 5–10 minutes between eye drops (or as directed by your doctor) to prevent one medication from washing out the other. Follow your doctor's instructions for the order and timing of each medication.
Please do not stop taking Pilocarpine even if you feel better, as this may worsen your condition. For the best advice, consult your doctor and do as recommended.
Yes, Pilocarpine is good for glaucoma as it helps treat high pressure inside the eye due to glaucoma. Talk to the doctor if you have any concerns.
Lie down and tilt your head backwards. Pull your lower eyelid gently with your index finger to form a pocket. Instil the number of drops advised by the doctor into the pocket of the lower eyelid. Close your eyes for 1-2 minutes.
It is not known if Pilocarpine causes the growth of eyelashes. However, it is used to lower high pressure in the eye and is not indicated for eyelash growth. Consult the doctor if you have any concerns.
The common side-effects of Pilocarpine are headache/brow ache, accommodative change, eye irritation, eye pain, blurred vision, and/or visual impairment. Most of these side effects of Pilocarpine do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
No, you should not apply the drops while wearing soft contact lenses. The preservatives in the solution can absorb into the lenses and discolour them. Remove your lenses before instilling the drops and wait at least 15 minutes before putting them back in. Talk to your doctor or pharmacist if you have questions about lens care.
This medication causes your pupils to shrink, which limits the amount of light that enters your eyes. This can temporarily reduce your ability to see clearly in dim environments or at night. Avoid driving or operating machinery in low light while using this medicine, and talk to your doctor if you experience severe vision changes.
Yes, mild headaches or aching around the brow area are common side effects, especially during the first few weeks of treatment as your eye muscles adjust. These symptoms usually improve over time. If your headaches are severe or do not go away, talk to your doctor.
Swallowing this medication can lead to serious systemic side effects like severe sweating, nausea, slow heart rate, or breathing difficulties. If anyone accidentally swallows the eye drops, seek emergency medical care. Talk to your doctor or pharmacist for further guidance.
Yes, but you must space them out. If your doctor has prescribed multiple eye drops, wait at least 5 to 10 minutes between applying each medication to prevent the first drop from being washed out by the second. Talk to your doctor or pharmacist to establish the best daily schedule.
The safety of this medication during pregnancy is not fully established, as systemic absorption could potentially affect the baby. It should only be used if the potential benefits outweigh the risks. If you are pregnant, planning to become pregnant, or breastfeeding, talk to your doctor.
