This should also include any supplements or recreational\/street drugs. The doctor or pharmacist at the clinic will treat this information in confidence.<\/p>\n<p>Your meds should come with a leaflet that includes the main interactions. If you don&#8217;t get printed information, please talk to your pharmacist when you are collecting your meds.<\/p>\n<h2>Using the Liverpool University website<\/h2>\n<p>It is easy to check for drug interactions using the online checker at Liverpool University HIV website:<br \/>\n<a href=\"https:\/\/www.hiv-druginteractions.org\/checker\">hiv-druginteractions.org\/checker<\/a><\/p>\n<p>This leading resource is easy to use and includes a detailed report if there are any concerns.<\/p>\n<ol>\n<li>Select your HIV meds from the menu in the left column.<\/li>\n<li>Select the interaction meds from the co-medication centre column.<\/li>\n<li>The interaction results are instantly generated in the right column.<\/li>\n<li>Click &#8216;more info&#8217; to get more details about each drug interaction. It also includes details about any research studies and the quality of the evidence.<\/li>\n<li>Click &#8216;Download PDF&#8217; for an individual printout of these results. You can also take this to show your doctor.<\/li>\n<\/ol>\n<p>The results use a traffic light system.<\/p>\n<ul>\n<li>Red means there is a serious interaction.<\/li>\n<li>Orange or amber means there is a potential concern and includes these details.<\/li>\n<li>Green means there is no interaction.<\/li>\n<\/ul>\n<h2>Drug interactions with food<\/h2>\n<p>Most HIV drugs do not interact with food, so it is okay to eat and drink a normal diet.<\/p>\n<p>But food can affect the way the some HIV drugs are absorbed by your body.<\/p>\n<p>Please follow any information about taking your meds with or without food though. This is an important part of adherence.<\/p>\n<p>If you need to take your meds with food, this is needed to get the right drug levels.<\/p>\n<h2>Drug interactions with supplements<\/h2>\n<p>Unless the supplement is widely used and known to cause interactions, there might not be any information of studies with your HIV meds.<\/p>\n<p>This is why i-Base do not recommend using supplements including herbs unless they are prescribed by your HIV doctor.<\/p>\n<p>One important interaction involves supplements that contain calcium, magnesium or aluminium and some <a href=\"https:\/\/i-base.info\/guides\/category\/arvs\/integrase-inhibitors\">HIV integrase inhibitors<\/a>. This involves separating the times you take your meds. Please see the individual information on each drug at links here to see whether this affects your meds: <a href=\"https:\/\/i-base.info\/guides\/8851\">dolutegravir<\/a>, <a href=\"https:\/\/i-base.info\/guides\/13754\">bictegravir<\/a>, <a href=\"https:\/\/i-base.info\/guides\/3567\">raltegravir<\/a>, <a href=\"https:\/\/i-base.info\/guides\/8928\">elvitegravir<\/a> and <a href=\"https:\/\/i-base.info\/guides\/15361\">cabotegravir<\/a>.<\/p>\n<p>Otherwise, most of these products have no evidence that they will do you any good.
