This can help reduce swelling in the nose, raise blood pressure in hospital settings, or reduce redness and swelling in certain medical situations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In South Africa, phenylephrine may be found in some cold and flu medicines, especially products marketed for a blocked nose. It is also available as an injection, but that form is used by trained healthcare professionals in a hospital or clinic, not at home.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why is phenylephrine used?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Blocked nose and sinus congestion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many people know phenylephrine as a decongestant in oral cold and flu tablets, capsules, or syrups. It is meant to make the blood vessels in the nose smaller, which may reduce swelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, there is debate about whether oral phenylephrine works well for nasal congestion. South African consumers should check the ingredient list on cold and flu products and ask a pharmacist whether phenylephrine is the best option for their symptoms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Low blood pressure in hospital<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Phenylephrine injection may be used in hospitals to raise blood pressure in certain situations, such as during anaesthesia or medical procedures. This is controlled medical use and should only be handled by healthcare professionals.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Eye or specialist medical use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Phenylephrine may also be used in some specialist settings, such as eye care, depending on the registered product and healthcare setting.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Who should be careful with phenylephrine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Speak to a doctor or pharmacist before using phenylephrine-containing products if you have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High blood pressure<\/li>\n\n\n\n<li>Heart disease, angina, heart failure, or an irregular heartbeat<\/li>\n\n\n\n<li>Overactive thyroid<\/li>\n\n\n\n<li>Diabetes<\/li>\n\n\n\n<li>Glaucoma<\/li>\n\n\n\n<li>Enlarged prostate or difficulty passing urine<\/li>\n\n\n\n<li>Poor circulation<\/li>\n\n\n\n<li>A history of stroke<\/li>\n\n\n\n<li>Pregnancy or breastfeeding<\/li>\n\n\n\n<li>Use of antidepressants or other stimulant\/decongestant medicines<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Possible side effects<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Phenylephrine can cause side effects, especially in people who are sensitive to stimulants or who have heart or blood pressure conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible side effects include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increased blood pressure<\/li>\n\n\n\n<li>Fast or irregular heartbeat<\/li>\n\n\n\n<li>Headache<\/li>\n\n\n\n<li>Dizziness<\/li>\n\n\n\n<li>Nervousness or restlessness<\/li>\n\n\n\n<li>Trouble sleeping<\/li>\n\n\n\n<li>Nausea<\/li>\n\n\n\n<li>Cold hands or feet<\/li>\n\n\n\n<li>Difficulty passing urine<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Get medical help urgently if you experience chest pain, severe headache, fainting, severe dizziness, shortness of breath, swelling of the face or throat, or a very fast or irregular heartbeat.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Can children use phenylephrine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Do not give cough, cold, or flu medicines to young children unless a doctor, clinic nurse, or pharmacist says it is safe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many combination cold and flu products contain several ingredients, such as pain relievers, antihistamines, caffeine, or decongestants. This increases the risk of giving too much of one ingredient by mistake.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For children, it is usually safer to ask a pharmacist for advice based on the child\u2019s age, weight, symptoms, and other medicines.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What can you use instead for a blocked nose?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For a common cold or seasonal congestion, ask a South African pharmacist about suitable options. Depending on your symptoms, alternatives may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Saline nose spray or drops<\/li>\n\n\n\n<li>Steam or humidified air<\/li>\n\n\n\n<li>Drinking enough fluids<\/li>\n\n\n\n<li>Paracetamol or ibuprofen for pain or fever, if suitable for you<\/li>\n\n\n\n<li>Allergy treatments, such as antihistamines or nasal corticosteroid sprays, if the cause is allergic rhinitis<\/li>\n\n\n\n<li>Short-term medicated nasal sprays, but only as directed, because overuse can worsen congestion<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid using more than one cold and flu product at the same time unless a healthcare professional confirms it is safe.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Practical tips when buying cold and flu medicine in South Africa<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before buying a product, check:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Active ingredients<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Look for \u201cphenylephrine hydrochloride\u201d or \u201cphenylephrine HCl\u201d on the label.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. What symptom you are treating<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A blocked nose, fever, cough, sore throat, and allergies may need different treatments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Your medical conditions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">High blood pressure, heart disease, pregnancy, and other conditions can affect what is safe.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Other medicines you take<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some combinations can raise blood pressure or increase side effects.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Ask the pharmacist<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pharmacists in South Africa can help you choose a safer and more suitable option.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">When should you see a doctor?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">See a doctor, clinic nurse, or pharmacist urgently if you have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Trouble breathing<\/li>\n\n\n\n<li>Chest pain<\/li>\n\n\n\n<li>Fever lasting more than 3 days<\/li>\n\n\n\n<li>Symptoms lasting more than 10 days<\/li>\n\n\n\n<li>Severe sinus pain or swelling around the eyes<\/li>\n\n\n\n<li>Thick green or yellow discharge with worsening symptoms<\/li>\n\n\n\n<li>A baby or young child who is unwell<\/li>\n\n\n\n<li>Pregnancy with severe cold or flu symptoms<\/li>\n\n\n\n<li>High blood pressure or heart disease and worsening symptoms<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Key takeaway<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Phenylephrine hydrochloride is used in some medicines for blocked noses and in hospital injections for low blood pressure. In South Africa, oral phenylephrine has been reviewed because of concerns that it may not work well as a nasal decongestant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For everyday cold and flu symptoms, check the label, avoid using multiple cold and flu products together, and ask your pharmacist for the safest and most effective option for you.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phenylephrine hydrochloride is a medicine ingredient used to narrow blood vessels.
