Betagan 0.5% Liquifilm is used to treat elevated intraocular pressure (high pressure inside the eye) in people with ocular hypertension and certain types of glaucoma. It lowers the pressure in the eye by decreasing the production of fluid and reduces the risk of vision loss.
Always wash your hands before using Betagan 0.5% Liquifilm. Use only the number of drops that your doctor has prescribed and wait for about five minutes between each drop. If you wear soft contact lenses, remove them before using the drops and wait for at least 15 minutes before putting them back in. If you are also using another eye medicine, wait for at least 10 minutes before using it. Read the leaflet that comes with the medicine for a full guide on how to use the drops and get the most benefit. Do not touch the tip of the dropper or bottle. This may lead to infection. You should use this medicine regularly to get the most benefit and it is best done at the same time(s) each day. If you want to stop using it, consult your doctor first.
 
The most common side effects are irritation or pain in the eye, watery or dry eyes, inflammation of the eyelid or surface of the eye, headache, and dizziness. There are other less common side effects affecting other parts of the body, some of which may be serious as Betagan 0.5% Liquifilm is absorbed into the systemic circulation. Read the leaflet that comes with the medicine and consult your doctor if you are bothered by any side effects.
 
You should not use this medicine if you have asthma, severe COPD, or a serious heart condition. Inform your doctor if you have, or have had, coronary heart disease, heart failure, diabetes, breathing problems, an overactive thyroid gland or liver, or kidney disease. It is not known if this medicine will harm an unborn baby but tell your doctor if you are pregnant or are planning to become pregnant. Betagan 0.5% Liquifilm should not be used if you are breastfeeding.
