Amlodipine and Blurred Vision: Is It a Side Effect, and When to Seek Care?

Blurred vision can occur with amlodipine, though it is not among the most common side effects. It has been described in official prescribing information as “abnormal vision” or “visual impairment,” sometimes accompanied by eye pain or double vision. ^{[1] [2]} If you notice new or worsening blurred vision while taking amlodipine, it’s reasonable to treat it as a potential medication-related effect and monitor closely. ^{[1] [2]}

What the official information says

• “Abnormal vision,” “visual impairment,” “diplopia (double vision),” and “eye pain” are listed among reported adverse effects of amlodipine tablets. ^{[1] [2]}
• Some combination products that include amlodipine also list “visual impairment/diplopia.” ^{[3] [4]}
• Guidance recommends contacting a clinician if blurred vision or any change in vision develops during treatment, as it can occasionally signal a more serious eye issue. ^[5]

Why blurred vision can happen

Amlodipine is a calcium channel blocker that relaxes blood vessels to lower blood pressure. In rare situations, calcium channel effects on ocular tissues may contribute to visual symptoms such as pupil changes (mydriasis), eye surface swelling (conjunctival chemosis), or fluid-related swelling, which could alter vision clarity. ^{[6] [7]} While these reactions are uncommon, they illustrate plausible mechanisms for visual disturbance during treatment. ^{[6] [7]}

When to seek medical attention

• Seek prompt medical advice if you develop blurred vision, eye pain, double vision, difficulty reading, or any new change in vision during or after starting amlodipine. This could indicate a significant eye problem that needs evaluation. ^[5]
• Urgent care (same day or emergency) is sensible if blurred vision is sudden and severe, accompanied by headache, nausea, halos around lights, eye redness/pain, or if you have known narrow angles/angle‑closure risk, since pupil changes could, in theory, precipitate angle closure in predisposed individuals. ^[6]
• Routine follow‑up is appropriate if symptoms are mild and short‑lived, but still inform your clinician so they can assess dose, drug interactions, and alternative causes. ^[5]

Practical steps you can take

• Do not stop amlodipine abruptly without guidance; instead, contact your prescriber to discuss symptoms and possible adjustments. ^[5]
• Note the timing of blurred vision relative to doses and any new medications, dehydration, or blood pressure changes, which can help your clinician differentiate causes. (Low blood pressure itself can sometimes make vision feel dim or blurred.)
• If you wear corrective lenses, check for non‑drug causes (dry eye, screen fatigue, new refractive needs), but still report the change since amlodipine can contribute. ^{[1] [2]}

Other eye and visual effects reported with amlodipine

Although rare, additional eye‑related events reported include conjunctivitis, eye pain, and double vision; ocular surface swelling (chemosis) has been described in case reports and resolved after discontinuation. ^{[1] [2] [7]} Topical exposure (not oral use) has been linked to prolonged pupil dilation, underscoring that calcium channel effects can involve the eye. ^[6]

---

Summary

• Yes, blurred vision is a recognized but uncommon side effect of amlodipine. ^{[1] [2]}
• Contact a clinician if blurred vision or any visual change occurs during treatment, because it can occasionally signal a more serious eye issue that needs assessment. ^[5]
• Seek urgent care for sudden, severe vision changes, eye pain, or symptoms suggestive of angle closure, especially if you have risk factors. ^[6]

Quick Reference Table: Visual Effects and Actions

Visual symptom	Known association with amlodipine	What to do
Blurred vision / abnormal vision	Reported in labeling	Contact your clinician to assess; do not stop medication without advice. [1] [2] [5]
Eye pain	Reported in labeling	Seek prompt medical advice; consider urgent evaluation if severe. [1] [2] [5]
Double vision (diplopia)	Reported in labeling and combo products	Notify your clinician; evaluate for neurological/ocular causes. [1] [2] [3] [4]
Conjunctival chemosis (eye surface swelling)	Case reports	Medical review; symptoms may improve after stopping amlodipine under guidance. [7]
Pupil dilation (mydriasis) after topical exposure	Case report	Urgent ophthalmic assessment if vision worsens; risk of angle closure in predisposed individuals. [6]
