Stromectol 3 mg ratings against off-label viral noise
Severe dizziness, collapse, confusion, or a roaring allergic picture after a microfilaricidal dose needs urgent care. Loa loa co-infection can turn ugly. This is not a home-kit drug.
Review pages that open with a virus waste the first screen. The US Stromectol label names Strongyloides stercoralis in the gut and Onchocerca volvulus in the skin. That is the indication set this board will rate.
A 3 mg tablet is a counting chip. The dose is micrograms per kilogram, then a tablet integer from the table. People who swallow “a few 3 mg” because a thread said so are not following either labeled lane.
Yuki Tanaka stamps weight first, indication second, empty-stomach water third. Viral dosing stories stay in the noise column. FDA’s consumer page is still the plain-language stop sign for COVID use. A 3 mg chip is not a respiratory course.
Adult worms in nodules still sit on the oncho card
Stromectol does not kill adult Onchocerca. Adults live in subcutaneous nodules that you may not even feel. Nodulectomy is still listed as a management option because removing the factory removes new microfilariae. A 150 mcg/kg day is a microfilaria job.
Travelers who want “one strip and done” for river blindness are rating the wrong endpoint. Repeat intervals in mass campaigns are often yearly; individuals may be retreated as soon as three months. That calendar is not a strongyloides calendar.
Eye microfilaria counts can tick up at day 3 and then fall. That labeled wrinkle is why oncho follow-up is not a selfie. Strongyloides patients should not be promised an eye story they do not have.
Quote the parasite when you quote the milligrams. Mixing 150 and 200 because both are “ivermectin doses” is the miss this review exists to catch.
Onchocerciasis sits at 150 mcg/kg on a different table
Onchocerciasis uses about 150 mcg/kg once. The tablet bins differ: 15-25 kg = 1, 26-44 kg = 2, 45-64 kg = 3, 65-84 kg = 4, 85 kg or more = calculate 150 mcg/kg. Copying the strongyloides row onto an oncho patient is a board miss.
Adult Onchocerca in nodules are not killed. The labeled job is microfilariae in skin (and the eye count story that follows). Mass campaigns often repeat yearly; individual retreatment can be considered as soon as three months.
Placebo-controlled work showed an 83.2% drop in skin microfilariae at day 3 and 99.5% at three months after 150 mcg/kg, with a >90% reduction held to twelve months in that adult study. Quote the indication when someone asks for “the ivermectin dose.”
| Body weight | 3 mg tablets (oncho ~150 mcg/kg) |
|---|---|
| 15-25 kg | 1 |
| 26-44 kg | 2 |
| 45-64 kg | 3 |
| 65-84 kg | 4 |
| 85 kg or more | Calculate 150 mcg/kg |
Heat, leftovers, and a weight change after the first count
A 3 mg strip that sat in a glove box is a poor second course. Heat and humidity are ordinary tablet enemies. Cabin-temperature travel is fine; a dashboard is not.
Weight changes rewrite the tablet integer. A count calculated at 64 kg is wrong at 82 kg. Recalculate from the table; do not “add one extra for luck.” Luck is how people invent a viral pack on top of a labeled bin.
Leftover tablets after a correct single day are not a rainy-day COVID stash. They are either a follow-up ID plan or a return-to-pharmacy story. This review will not bless a bathroom stockpile.
Children’s weights sit in the low bins. Do not split adult improvisation onto a 16 kg child. The 15-24 kg strongyloides row is one tablet, empty stomach, water, indication first.
200 mcg/kg is a tablet count, not a meme
Strongyloidiasis: one oral dose aimed at about 200 mcg/kg. The 3 mg table runs 15-24 kg = 1 tablet, 25-35 kg = 2, 36-50 kg = 3, 51-65 kg = 4, 66-79 kg = 5, and 80 kg or more = calculate 200 mcg/kg. Take it on an empty stomach with water.
Follow-up stool exams three to four weeks later check eradication. Extra doses are not routine on the label; immunocompromised patients are a specialist problem, not a second bottle from a forum.
Registration work used 170 to 200 mcg/kg once and beat albendazole 200 mg twice daily for three days on stool-clear criteria. Versus thiabendazole 25 mg/kg twice daily for three days, single-dose ivermectin matched cure with a simpler day.
| Body weight | 3 mg tablets (strongyloides ~200 mcg/kg) |
|---|---|
| 15-24 kg | 1 |
| 25-35 kg | 2 |
| 36-50 kg | 3 |
| 51-65 kg | 4 |
| 66-79 kg | 5 |
| 80 kg or more | Calculate 200 mcg/kg |
Mazzotti numbers and the Loa loa screen
Onchocerciasis treatment can stir Mazzotti-type reactions as microfilariae die: pruritus 27.5%, skin edema or urticarial rash 22.7%, fever 22.6%, inguinal node tenderness 13.9% in the labeled 100-200 mcg/kg adult set. Hydration, recumbency, and clinician-directed steroids have been used for the ugly hypotensive ones.
People with heavy Loa loa and onchocerciasis can develop encephalopathy after a microfilaricide. Pretreat assessment and close follow-up belong on the chart if West or Central African exposure is real. Neurotoxicity reports also exist without Loa loa; they are rare and still a reason not to self-dose.
Strongyloides patients should not be promised an oncho-style eye reaction. They should be promised a stool check. Immunosuppression plus possible Strongyloides is an ID problem, sometimes before steroids, not a 3 mg souvenir.
Chips the viral reviews drop
- Weigh in kilograms. Then count 3 mg tablets.
- Empty stomach, water, one labeled indication.
- Stool follow-up for strongyloides.
- Loa loa history before oncho treatment when exposure fits.
Two labeled parasites. That is the whole US card
Intestinal (nondisseminated) strongyloidiasis and onchocerciasis. Cure rates of 64-100% after a single 200 mcg/kg dose sit in the strongyloides evidence block. That sentence does not license a respiratory self-treat.
FDA consumer material remains explicit: do not use ivermectin to treat or prevent COVID-19. Veterinary pastes are a different concentration and a different disaster. ID consults on Bay Street still triage paste exposures separately from labeled tablet counts.
Scabies and other unlisted uses are guideline or jurisdiction stories, not this US tablet card. If your clinician is treating something else, that plan is theirs. This review will not widen the label to win a comment thread.
Immunosuppression and the extra Strongyloides problem
Steroids, transplant drugs, and HTLV-1 change Strongyloides from a stool story into a dissemination risk. The labeled single 200 mcg/kg day is written for intestinal, nondisseminated disease. Hyperinfection is an ID plan and may need repeated or prolonged ivermectin the label does not fully script.
Screening before high-dose steroids in someone with endemic exposure is a clinic habit, not a 3 mg souvenir in the drawer. Paste from a farm store is still the wrong concentration even if the fear is real.
This board will not publish a home “cover me while I start prednisone” count. If immunosuppression is on the chart, the 3 mg tablets belong to the team that owns the steroid, not to a review thread.
Follow-up stools still matter after a labeled day. A single negative sample is weaker than the two-exam, three-to-four-week standard the trials used.
Scabies protocols versus this US Stromectol card
Some jurisdictions and hospital protocols use ivermectin for scabies. That is a guideline or local-monograph story with its own repeats and contact rules. The US Stromectol PI you can open today still lists strongyloides and onchocerciasis.
This review will not print a scabies calendar to win a search. If your clinician is treating mites, their protocol owns the days. Empty-stomach water and weight math still travel.
Household sharing of leftover 3 mg “so nobody else itches” is how children get an adult bin. Weigh each person. Indication first. Do not run a family campaign from a travel blister.
Crusted scabies is an institutional ID problem, not a five-tablet weekend. Paste and “horse strength” rumors stay in the noise column here too.
No Stromectol coupon on this ledger
Brand Stromectol cash is not a number this board will invent. Nearest published US pair is generic ivermectin 3 mg x 10 at $36.45 / $23.76 on GoodRx.
Have a clerk price Costco, Meijer, H-E-B, or Walgreens for the 3 mg count your script actually names. Weight dose is mcg/kg, not a COVID pack. Sephira does not dispense.
| Pharmacy | Strength / count | How the window works | Official page |
|---|---|---|---|
| Costco | Ask 3 mg brand | US window may only stock generic ivermectin | Costco pharmacy |
| Meijer | Ask 3 mg brand | No invented Stromectol coupon | Meijer pharmacy |
| H-E-B | Ask 3 mg brand | Nearest cash is the generic 3 mg board | H-E-B pharmacy |
| Walgreens | Ask 3 mg brand | Weight dose is mcg/kg, not a COVID pack | Walgreens pharmacy |
Water, empty stomach, Tmax near four hours
Both labeled doses want an empty stomach and water. Food changes the curve; the PI’s PK work used fasting adults. Peak of the major component sits near four hours after a 12 mg fasting dose (mean about 165 mcg/kg in those studies).
Plasma half-life is about 18 hours. Less than 1% of the dose leaves in urine; feces carry drug and metabolites over roughly twelve days. That is why a “flush it out with water” story after a wrong dose is theatre.
Mean Cmax values in those fasting 12 mg studies were 46.6 and 30.6 ng/mL with wide ranges. Do not treat a single plasma number as a home target. The weight-dose signal keeps the arithmetic on the table.
| Absorption | Oral; labeled administration is empty stomach with water; Tmax about 4 hours. |
|---|---|
| Distribution | Widely distributed; highly protein bound. |
| Metabolism | |
| Excretion | Half-life about 18 hours; almost all fecal, <1% urinary. |
Stool timing and what “cured” meant in the albendazole trials
Cure in the comparative work meant no larvae in at least two stools three to four weeks after therapy. That is a slower victory lap than a forum “I feel better tomorrow.” Feeling better at day two does not close the case.
Ivermectin 170-200 mcg/kg once beat albendazole 200 mg twice daily for three days on that stool rule. Versus thiabendazole 25 mg/kg twice daily for three days, the single ivermectin day matched cure and spared a messier three-day regimen.
Open-label series reported 64-100% cure after one 200 mcg/kg day. The spread is why stool checks exist. Quote the range, not a 100% promise, when someone rates the tablet like an antibiotic course.
Oncho “success” is a skin microfilaria drop, not adult-worm death. Do not mix those endpoints when a traveler asks whether one 3 mg strip “cleared everything.”
Weight-dose close, not a COVID close
Rate the kilogram, the indication, and the empty-stomach water. Leave the viral pack in the noise column. 3 mg is a chip, not a course.
Keep the short cards at label lane and weight dose. Yuki Tanaka, 21 August 2026. [email protected].
