Let&#8217;s talk about jammed pens and how to fix them.<\/p>\n\n\n\n<h2 id=\"h-attaching-mounjaro-needles\" class=\"wp-block-heading\">Attaching Mounjaro Needles<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The needle attachment step is crucial. Here&#8217;s what you need to do &#8211; attach the needle exactly straight. Watch the inner needle pierce the bulb at the pen&#8217;s top. For Mounjaro, the bulb is red, and for <a class=\"wpil_keyword_link\" href=\"https:\/\/www.simpleonlinepharmacy.co.uk\/online-doctor\/weight-loss\/wegovy\/\" title=\"Wegovy\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"20\">Wegovy<\/a>, it&#8217;s yellow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Be careful not to hit the rim around the bulb with the inner needle. If you attach the needle incorrectly, here&#8217;s what can happen. The inner needle might not pierce the bulb. The needle will look attached, but the medication won&#8217;t be able to flow.&nbsp; If you press the plunger too hard in this situation, the bulb could expand and burst, ruining the pen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#8217;s <a href=\"https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/weight-loss\/mounjaro\/a-guide-to-mounjaro-injections-sites\/\">recommended that you rotate injection sites weekly<\/a>.<\/p>\n\n\n\n<h2 id=\"h-how-to-use-mounjaro-kwikpen\" class=\"wp-block-heading\">How to use Mounjaro Kwikpen<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Wash your hands with soap and water to ensure cleanliness.<\/strong><\/li>\n\n\n\n<li><strong>Inspect the pen before use:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Check the expiration date<\/li>\n\n\n\n<li>Look for any visible damage<\/li>\n\n\n\n<li>Verify the medication appears clear and colourless<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Attach a new needle to the pen, ensuring it&#8217;s firmly secured.<\/strong><\/li>\n\n\n\n<li><strong>Prime the pen:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Turn the dose knob slowly until you hear 2 clicks<\/li>\n\n\n\n<li>Point the needle upward<\/li>\n\n\n\n<li>Press the dose knob to release any air bubbles and confirm the pen is working<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Set your dose:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Turn the dose knob to your prescribed dosage (typically starting at 2.5 mg, increasing as directed by your healthcare provider)<\/li>\n\n\n\n<li>Listen for clicks to confirm the correct dose is selected<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Choose and prepare the injection site:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Common sites: abdomen, thigh, or upper arm<\/li>\n\n\n\n<li>Rotate sites to avoid irritation<\/li>\n\n\n\n<li>Pinch the skin gently if preferred<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Inject the medication:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Insert the needle at a 90-degree angle into the skin<\/li>\n\n\n\n<li>Press down the dose knob firmly<\/li>\n\n\n\n<li>Count slowly to 5 while keeping the needle in place<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Withdraw and verify:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Pull the needle straight out of the skin<\/li>\n\n\n\n<li>Check that the dose counter returns to 0<\/li>\n\n\n\n<li>Apply gentle pressure with a tissue if needed<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Secure the pen:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Remove the needle from the pen and place in&nbsp;<a href=\"https:\/\/www.simpleonlinepharmacy.co.uk\/medications\/1-litre-sharps-bin\/\" target=\"_blank\" rel=\"noopener\">sharps bin<\/a><\/li>\n\n\n\n<li>Replace the pen cap<\/li>\n\n\n\n<li>Store the pen as directed (typically in the refrigerator)<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\t\t<div data-elementor-type=\"container\" data-elementor-id=\"19015\" class=\"elementor elementor-19015\" data-elementor-post-type=\"elementor_library\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d726aa8 e-con-full e-flex e-con e-parent\" data-id=\"d726aa8\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-38f2150 e-con-full e-flex e-con e-child\" data-id=\"38f2150\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-470d4c4 elementor-widget elementor-widget-heading\" data-id=\"470d4c4\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<div class=\"elementor-heading-title elementor-size-default\"><div><span style=\"font-size: 2rem\">Save on your next Mounjaro order<\/span><\/div><\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3944e14 elementor-widget elementor-widget-heading\" data-id=\"3944e14\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<div class=\"elementor-heading-title elementor-size-default\"><div><span style=\"font-size:1rem\">Starting from<b> \u00a3129<\/b> when you<b> Subscribe &amp;

Priming Mounjaro Pens<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When removing the needle, be cautious. If you catch the bulb, you could dislodge it, making the rest of the pen unusable.&nbsp; In order to avoid these issues, always attach the needle straight and ensure that it pierces the bulb correctly. Don&#8217;t use excessive force on the plunger if you suspect a problem.<\/p>\n\n\n\n<p>Handle the needle carefully when you&#8217;re removing it. Follow the correct priming procedure for your medication. Speaking of priming, for Wegovy, prime only once.&nbsp; Priming more than once can waste your doses. For Mounjaro, prime before every use.<\/p>\n\n\n\n<h2 id=\"h-how-long-mounjaro-lasts\" class=\"wp-block-heading\">How Long Mounjaro Lasts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The product is designed to last for 30 days. Using it longer isn&#8217;t recommended and may affect the effectiveness of it. Always follow your GP&#8217;s instructions about your health. If you have concerns about your dosage, please consult our team.&nbsp; We can adjust your treatment safely if needed.<\/p>\n\n\n\n<h3 id=\"h-authorship\" class=\"wp-block-heading\">Authorship<\/h3>\n\n\n\t\t<div data-elementor-type=\"container\" data-elementor-id=\"14992\" class=\"elementor elementor-14992\" data-elementor-post-type=\"elementor_library\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ec8f702 e-flex e-con-boxed e-con e-parent\" data-id=\"ec8f702\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-73a1dc0 elementor-position-left elementor-vertical-align-middle elementor-widget__width-auto elementor-widget elementor-widget-image-box\" data-id=\"73a1dc0\" data-element_type=\"widget\" data-widget_type=\"image-box.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<div class=\"elementor-image-box-wrapper\"><figure class=\"elementor-image-box-img\"><a href=\"https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/aamina-rafiq\/\" tabindex=\"-1\"><img decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/wp-content\/uploads\/2025\/01\/aamina-rafiq-headshot.jpg\" class=\"attachment-thumbnail size-thumbnail wp-image-13549\" alt=\"Aamina Rafiq - Superintendent Pharmacist (headshot)\" srcset=\"https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/wp-content\/uploads\/2025\/01\/aamina-rafiq-headshot.jpg 150w, https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/wp-content\/uploads\/2025\/01\/aamina-rafiq-headshot-70x70.jpg 70w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/><\/a><\/figure><div class=\"elementor-image-box-content\"><h4 class=\"elementor-image-box-title\"><a href=\"https:\/\/www.simpleonlinepharmacy.co.uk\/health-advice\/aamina-rafiq\/\"><h4>Authored by Aamina Rafiq<\/h4><\/a><\/h4><p class=\"elementor-image-box-description\"><b>Superintendent Pharmacist - GPhC <a href=\"https:\/\/www.pharmacyregulation.org\/registers\/pharmacist\/registrationnumber\/2216332#registers-search\" target=\"_blank\" rel=\"noopener\">2216332<\/a><\/b>\n<br>\nAamina is the Superintendent Pharmacist for Simple Online Pharmacy.
