Be careful about drinking alcohol as Glytrin may affect you more than usual. Both alcohol and Glytrin may lower your blood pressure and slow down your reactions.

If you are, or think you might be pregnant, ask your doctor for advice before taking this medicine. Glytrin should not be used if you are breastfeeding.

Your reactions may slow down. Therefore, you should avoid driving and using machinery whilst taking Glytrin.

This medicine contains 7.5 mg of alcohol (ethanol) in each spray. The amount in one spray of this medicine is equivalent to less than 1 ml beer or 1 ml wine.

The small amount of alcohol in this medicine will not have any noticeable effects.

Continuous use of Glytrin and other nitrates may reduce effectiveness at relieving your symptoms, so high continuous doses should be avoided.

Special treatment is not normally required. Overdose symptoms are usually the same as the stated side effects. Some people may experience a reaction similar to shock, with nausea, weakness and sweating. If you feel faint sit down and raise your legs. Contact your doctor if your symptoms do not improve. Rarely a bluish colour to lips/fingers may occur (cyanosis or methaemoglobinaemia). If this happens contact your doctor immediately.

• An allergic skin reaction (with or without rash).
• Tongue blistering (may affect up to 1 in 100 people)
• Fainting
• A severe fall in blood pressure on standing up

• Transient hypoxaemia (deprived oxygen supply) (bluish colouration of the lips, hands or feet, may be followed by loss of consciousness)
• Patients with coronary heart disease may experience a restriction in blood supply.

Continuous use may result in a tolerance to Glytrin, reducing its effectiveness. If symptoms are not relieved, medical advice should be sought immediately.
