In reality, <strong>saw palmetto side effects<\/strong> are uncommon and mild for most adults, but there are situations and drug interactions worth knowing about. Here are 7 practical points covering reactions, warnings and who should skip this herb.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Stomach_Upset_The_Most_Common_of_Saw_Palmetto_Side_Effects\"><\/span>1. Stomach Upset: The Most Common of Saw Palmetto Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The complaint people report most often is mild stomach pain, nausea, constipation or loose stools. These usually ease when you take the capsule with food and split the dose across the day. If they persist, lower the dose or stop the supplement. Practical timing tips are in our <a href=\"https:\/\/nostylelike.net\/en\/saw-palmetto-dosage\/\">saw palmetto dosage<\/a> guide.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Headache_and_Dizziness_as_Saw_Palmetto_Side_Effects\"><\/span>2. Headache and Dizziness as Saw Palmetto Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Some people get a mild headache, dizziness or tiredness in the first days. These saw palmetto side effects are usually temporary, but if they keep coming back or get worse, stop and talk to your doctor.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Bleeding_Risk_and_Surgery\"><\/span>3. Bleeding Risk and Surgery<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are rare reports of bleeding linked to the herb, and in theory it may affect clotting. So:<\/p>\n<ul>\n<li>Stop it about two weeks before any surgery or dental extraction.<\/li>\n<li>Ask your doctor before combining it with warfarin, aspirin, clopidogrel or any other blood thinner.<\/li>\n<li>Watch for unusual bruising or bleeding gums.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"4_Hormonal_Activity_and_Who_Should_Avoid_It\"><\/span>4. Hormonal Activity and Who Should Avoid It<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The herb may act on hormones, which makes some saw palmetto side effects more relevant for certain groups:<\/p>\n<ul>\n<li>Pregnant and breastfeeding women should not use it, because of a possible effect on fetal hormones.<\/li>\n<li>Children and anyone under 18.<\/li>\n<li>People on birth control pills or hormone therapy, unless their doctor approves.<\/li>\n<\/ul>\n<p>This is why the Nature&#8217;s Way label clearly states it is intended for men and not for women or children.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_PSA_Testing_and_Prostate_Medicines\"><\/span>5. PSA Testing and Prostate Medicines<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you have regular PSA blood tests, tell your doctor you take saw palmetto so the result is read correctly. Do not combine it with finasteride or dutasteride unless your doctor knows, because research on combining them is limited.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6_The_Bigger_Risk_Delayed_Diagnosis\"><\/span>6. The Bigger Risk: Delayed Diagnosis<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the most important indirect saw palmetto side effects is relying on it for urinary symptoms without a check-up. Frequent night-time urination or a weak stream may come from benign enlargement, infection, or less often prostate cancer. Any urinary symptoms should be assessed by a doctor before you start a supplement. The large STEP and CAMUS trials found that saw palmetto did no better than placebo for enlarged prostate symptoms, although older, smaller trials had suggested a modest benefit.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"7_Warning_Signs_to_Stop_Immediately\"><\/span>7. Warning Signs to Stop Immediately<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Yellowing of the eyes or skin, or very dark urine.<\/li>\n<li>Severe abdominal pain.<\/li>\n<li>Unusual bleeding or blood in the urine.<\/li>\n<li>Rash, facial swelling or difficulty breathing.<\/li>\n<\/ul>\n<p>These saw palmetto side effects are rare, but they call for stopping the supplement and seeing a doctor right away.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Who_Is_More_Likely_to_Notice_Saw_Palmetto_Side_Effects\"><\/span>Who Is More Likely to Notice Saw Palmetto Side Effects?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The risk rises in people who take many medicines, such as older adults treated for blood pressure, diabetes or heart disease, because every extra drug adds a chance of interaction. The same applies to people with liver disease or clotting disorders, and anyone preparing for surgery or an endoscopy. Keep a written list of all your medicines and supplements and show it to your doctor or pharmacist, naming the herb clearly, since supplements are often forgotten.
