How to take enalapril
You may experience side effects such as dizziness and feeling tired or faint after you take your first dosage. You should take your first dose at night as this will make any side effects less noticeable.

There are four different dosages available: 2.5mg, 5mg, 10mg and 20 mg. You should take a tablet at the recommended dosage once per day with a glass of water and with or without food.
Generally, your starting dose will be 2.5mg or 5mg, however, this may be raised depending on your response to the treatment.
Children must not use enalapril.
Over 65’s and anyone with renal impairment should take the lower suggested dose of 2.5mg.

Enalapril is a treatment for hypertension or high blood pressure. Enalapril is one of a group of hypertension treatments called the ACE (angiotensin-converting enzyme) inhibitors. Enalapril can be taken to avoid serious health implications that may occur if your blood pressure rises too high, like heart failure, liver failure, and stroke. Enalapril can also be used to treat patients with heart failure.
Enalapril is an angiotensin-converting enzyme (ACE) inhibitors. It stops your body creating the hormone angiotensin II. Enalapril inhibits the angiotensin-converting enzyme and this action causes the smooth muscle in your blood vessels to relax, thereby opening them to increase blood flow. Enalapril also reduces the amount of water put back into your blood by the kidneys resulting in decreased blood pressure.
There are no specific foods that will change how enalapril works. However, you should be aware that your high blood pressure might be caused by a diet high in salt, cholesterol and fat; the treatment would work better if you change your diet for the better as well to reduce your blood pressure.
Alcohol can exacerbate side effects such as feeling faint or dizzy because the combination can drop your blood pressure. It’s important to be aware of this if you drink any alcohol.
The tablets are round and white with the dosage marked on one side, and a break line marked on the other.
Non-steroidal anti-inflammatory drugs (NSAID’s) such as ibuprofen, diclofenac or high dose aspirin can interact with enalapril. You should use alternative painkillers if and when you need them. Speak to your doctor if you have any concerns.
Enalapril must be prescribed. Enalapril should be taken by people over 18 only, unless otherwise recommended by a doctor.
