&#8211; Amlodipine uses, dose and side effects"},"content":{"rendered":"\n<p>5 mg and 10 mg&nbsp;tablets<br>amlodipine<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Norvasc is and what it is used for<\/h2>\n\n\n\n<p>Norvasc contains the active substance amlodipine which belongs to a group of medicines called calcium channel blockers.<\/p>\n\n\n\n<p>Norvasc is used to treat high&nbsp;blood pressure&nbsp;(&nbsp;hypertension&nbsp;) or a special type of chest pain called angina.&nbsp;A rare form of this is Prinzmetal&#8217;s angina or variant angina.<\/p>\n\n\n\n<p>In patients with high\u00a0blood pressure, the drug reduces the resistance in the blood vessels, so that the blood can pass more easily.\u00a0In patients with angina, Norvasc works by increasing blood flow to the heart muscle, which then receives more oxygen.\u00a0That way, chest pain is prevented.\u00a0The drug does not provide immediate relief of chest pain in angina.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What you need to know before using Norvasc<\/h2>\n\n\n\n<h2 class=\"wp-block-heading\">Do not take Norvasc<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>if you are allergic (hypersensitive) to amlodipine or any of the other ingredients of this medicine (listed in section 6), or to any other calcium channel blocker.&nbsp;Symptoms may include&nbsp;itching&nbsp;, redness of the skin or difficulty breathing<\/li><li>if you have very low&nbsp;blood pressure&nbsp;(&nbsp;hypotension&nbsp;)<\/li><li>if you have a narrowing of the aortic valve (aortic stenosis) or&nbsp;cardiogenic&nbsp;shock&nbsp;(a condition in which the heart is unable to supply the body with sufficient amounts of blood)<\/li><li>if you have&nbsp;heart failure&nbsp;after a heart attack.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Warnings and cautions<\/h2>\n\n\n\n<p>Talk to your doctor or pharmacist before taking Norvasc.<\/p>\n\n\n\n<p>Tell your doctor if you have or have had any of the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>recent heart attack<\/li><li>heart failure<\/li><li>very high&nbsp;blood pressure&nbsp;(hypertensive crisis)<\/li><li>liver disease<\/li><li>if you are older and your&nbsp;dose&nbsp;needs to be increased<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Children and young people<\/h2>\n\n\n\n<p>Norvasc has not been studied in children under 6 years of age.&nbsp;Norvasc should only be used to treat&nbsp;hypertension&nbsp;in children and adolescents between 6 and 17 years of age (see section 3).<\/p>\n\n\n\n<p>For more information, talk to your doctor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other medicines and Norvasc<\/h2>\n\n\n\n<p>Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.<\/p>\n\n\n\n<p>Norvasc may affect or be affected by other medicines, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>ketoconazole&nbsp;, itraconazole (antifungal)<\/li><li>ritonavir, indinavir, nelfinavir (so-called&nbsp;protease inhibitors&nbsp;used to treat&nbsp;HIV&nbsp;)<\/li><li>rifampicin, erythromycin, clarithromycin (&nbsp;antibiotics&nbsp;)<\/li><li><em>Hypericum perforatum<\/em>&nbsp;(&nbsp;St. John&#8217;s wort&nbsp;)<\/li><li>verapamil,&nbsp;diltiazem&nbsp;(heart medicine)<\/li><li>dantrolene (&nbsp;infusion&nbsp;for severe disorders of body temperature)<\/li><li>tacrolimus, sirolimus, <a href=\"https:\/\/zeepedia.com\/medical\/medicines\/torisel\/\">temsirolimus<\/a> and everolimus (medicines used to change the way the immune system works)<\/li><li>simvastatin&nbsp;(cholesterol lowering drug)<\/li><li>ciclosporin (medicines that suppress the immune system)<\/li><\/ul>\n\n\n\n<p>Norvasc may lower your\u00a0blood pressure\u00a0further if you are already taking other medicines for high\u00a0blood pressure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Norvasc with food, drink and alcohol<\/h2>\n\n\n\n<p>If you are taking Norvasc, do not eat grapefruit or drink grapefruit juice.\u00a0Grapefruit and grapefruit juice can lead to an increase in the amount of the active substance amlodipine in the blood, which can lead to an unpredictable increase in Norvasc&#8217;s blood pressure-lowering effect.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pregnancy, breastfeeding and fertility<\/h2>\n\n\n\n<p><em>Pregnancy<\/em><\/p>\n\n\n\n<p>The safety of amlodipine during pregnancy has not been established.&nbsp;If you think you are pregnant or planning to become pregnant, tell your doctor before taking Norvasc.<\/p>\n\n\n\n<p><em>Breast-feeding<\/em><\/p>\n\n\n\n<p>Amlodipine passes into breast milk in small amounts.\u00a0If you are breastfeeding or about to start breastfeeding, tell your doctor before taking Norvasc.<\/p>\n\n\n\n<p>Ask your doctor or pharmacist for advice before taking any medicine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Driving and using machines<\/h2>\n\n\n\n<p>Norvasc may affect your ability to drive or use machines.\u00a0If you feel unwell, dizzy or tired, or have headaches from the tablets, do not drive or use machines.\u00a0Contact your doctor immediately.<\/p>\n\n\n\n<p>You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened vigilance.\u00a0One of the factors that can affect your ability in these respects is the use of drugs due to their effects and\/or\u00a0side effects.\u00a0Descriptions of these effects and\u00a0side effects\u00a0can be found in other sections.\u00a0Read all the information in this leaflet for guidance.\u00a0If you are not sure, talk to your doctor or pharmacist.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Norvasc contains sodium<\/h2>\n\n\n\n<p>This medicine contains less than 1 mmol&nbsp;sodium&nbsp;(23 mg) per tablet, ie

grapefruit juice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Use for children and adolescents<\/h2>\n\n\n\n<p>The recommended starting dose for children and adolescents (6-17 years) is 2.5 mg daily.&nbsp;The maximum recommended&nbsp;dose&nbsp;is 5 mg daily.&nbsp;Norvasc 5 mg tablets can be divided into halves to obtain a&nbsp;dose&nbsp;of 2.5 mg.<\/p>\n\n\n\n<p>You must take the tablets at all times.\u00a0Do not wait until the tablets run out before going to the doctor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you use more Norvasc than you should&nbsp;<\/h2>\n\n\n\n<p>If you have ingested too much medicine or if e.g.\u00a0If a child has ingested the medicine by mistake, contact a doctor or hospital for risk assessment and advice.<\/p>\n\n\n\n<p>If you take too many tablets,\u00a0your blood pressure\u00a0may be low or even dangerously low.\u00a0You may feel dizzy, unsteady, faint, or weak.\u00a0If the\u00a0blood pressure\u00a0drops low enough, you can

time.<\/p>\n\n\n\n<p>Do not take a double\u00a0dose\u00a0to make up for a forgotten\u00a0dose.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you stop using Norvasc<\/h2>\n\n\n\n<p>Your doctor will tell you how long to take this medicine.&nbsp;Your illness may return if you stop taking the medicine earlier.<\/p>\n\n\n\n<p>If you have any further questions on the use of this product, ask your doctor or pharmacist.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Possible side effects<\/h2>\n\n\n\n<p>Like all medicines, this medicine can cause\u00a0side effects, although not everybody gets
