blurred vision,
restlessness,

It may increase blood pressure in a small proportion of individuals, and is therefore contraindicated in patients with arterial hypertension, or others in whom a rise in blood pressure would be harmful (e.g. patients with angina). Pulmonary hypertension, a problem in some other anorectics, is not a recognised side-effect.

If Meridia makes you dizzy or lightheaded, avoid driving or engaging in activities requiring alertness. Alcohol can increase unwanted side effects of dizziness. Do not drink alcohol while taking Meridia.
