Before using Combigan, discuss your medical history and all medications you are taking with your healthcare provider. Following proper administration instructions can help maximize the effectiveness of the medication and reduce the risk of side effects.
Follow Your Prescribed Dosage
Use Combigan exactly as prescribed by your healthcare provider. Do not change your dosage, stop treatment, or use the medication more often than directed without first consulting your healthcare provider, even if you believe a different dose may be more appropriate.
Proper Storage
Store Combigan at room temperature and protect it from excessive heat, moisture, and direct light.
To help maintain the quality of the medication:
- Keep the bottle tightly closed when not in use.
- Store it in a safe, dry location.
- Keep it out of the reach of children and pets.
Prevent Contamination
To reduce the risk of eye infections or contamination:
- Do not allow the dropper tip to touch your eye.
- Avoid touching the dropper tip with your fingers.
- Do not let the tip come into contact with any surface.
Always replace the cap securely after each use.
Using Other Eye Medications
If you use other ophthalmic medications, wait at least 10 minutes between applications.
This helps ensure each medication is absorbed properly and prevents one eye drop from washing out another.
Contact Lens Use
If you wear soft contact lenses:
- Remove them before applying Combigan.
- Wait at least 15 minutes after using the drops before reinserting your lenses.
This helps prevent the medication or preservatives from being absorbed into the lenses.
Drug Interactions
Use caution when taking Combigan with certain medications, including:
- Other eye medications
- Blood pressure medications (antihypertensives)
- Cardiac glycosides and certain heart medications
These combinations may increase the risk of side effects or affect how the medications work. Be sure to provide your healthcare provider with a complete list of all prescription medications, over-the-counter products, vitamins, and supplements you use.
Respiratory and Heart-Related Effects
Because Combigan contains timolol, a beta blocker, it may occasionally cause serious respiratory or cardiovascular side effects in susceptible individuals.
Tell your healthcare provider if you have a history of:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Heart failure
- Slow heart rate (bradycardia)
- Other heart rhythm disorders
Seek medical attention if you experience:
- Difficulty breathing
- Wheezing
- Chest pain
- Fainting
- Severe dizziness
- Unusually slow heartbeat
Depression and Mood Disorders
Combigan should be used with caution in people with a history of depression or certain mood disorders. Inform your healthcare provider if you have experienced depression or other mental health conditions in the past.
Use in Children
Combigan must not be used in infants younger than 2 years of age.
In general, Combigan is not routinely recommended for children and adolescents between 2 and 17 years of age, unless specifically prescribed and closely monitored by a healthcare provider.
When to Contact Your Healthcare Provider
Contact your healthcare provider if you experience:
- Eye irritation that does not improve
- Changes in vision
- Difficulty breathing
- Slow or irregular heartbeat
- Severe dizziness or fainting
- Symptoms of depression or mood changes
Any unusual or severe side effects
