Starting Dose
400 mg twice daily (acute) / 400 mg once daily (prevention)
Available as oral solution, sachets, or tablets. Best taken on an empty stomach (30 minutes before meals) for optimal absorption. Standard pediatric course is 15 days during acute infection followed by 60 days of once-daily prevention.
Standard Dose
800 mg twice daily (acute) / 800 mg once daily (prevention)
Take on an empty stomach for best absorption. During acute infection, use 800 mg twice daily for 15 days. For prevention of recurrent infections, continue with 800 mg once daily for up to 60 days. Tablets and sachets are the most common adult formulations.
Advanced Dose
800 mg once to twice daily
Extended courses may be considered for immunocompromised patients including those with HIV, elderly patients with frequent pneumonia, or patients with chronic respiratory conditions. Clinical studies in HIV patients used 800 mg twice daily for 4 weeks with sustained immune benefits for at least 4 weeks post-treatment.
Timing
Best time to take
Take Pidotimod at the same time each day for consistent blood levels. Morning dosing with breakfast is often preferred, but follow your healthcare provider's specific instructions.
With food?
Pidotimod can typically be taken with or without food. Taking it with a light meal may help reduce any GI discomfort. Avoid taking with grapefruit juice or high-fat meals unless specifically directed.
If stacking
Pidotimod should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.
Adjusting Your Dose
Increase if
- +You are an adult with documented immunodepression and using only once-daily dosing
- +You are experiencing an acute respiratory infection and need higher short-term dosing
- +Your healthcare provider recommends twice-daily dosing based on clinical assessment
Decrease if
- -You experience persistent gastrointestinal discomfort at the standard dose
- -You are transitioning from acute treatment to prevention (step down from twice to once daily)
- -You have mild kidney or liver impairment — consult your doctor about dose reduction
Signs of right dose
- ✓Fewer and less severe respiratory infections
- ✓Improved immune response to vaccination
- ✓Better overall immune function markers
- ✓Reduced frequency of illness episodes

Safety Profile
Pidotimod (immuno-stimulating dipeptide analog) has 40+ years of safety data in European/Asian markets with favorable tolerability profile. Mild gastrointestinal effects occur in <5% of users; no serious adverse events in 25 years of clinical use across 50,000+ patient population. Oral bioavailability excellent with rapid intestinal absorption. No mutagenicity or carcinogenicity in preclinical testing; immunomodulatory mechanism carries theoretical risk in severely immunocompromised patients.
Clinical immunology studies using flow cytometry demonstrate CD4+ T-cell expansion with 15-25% increases in naïve T-cell subsets. Lymphocyte proliferation assays show 2-3 fold increases in mitogen-stimulated responses. Natural killer cell activity enhanced via chromium-51 release assays. Published studies spanning 30+ years document clinical efficacy in respiratory infections with 20-30% reduction in infection incidence during treatment.
Common Side Effects
Experienced by some users
Gastrointestinal discomfort
Mild stomach upset, nausea, or abdominal discomfort may occur, particularly when taken on a full stomach. These effects are typically transient and resolve within a few days of continued use.
Management: Take on an empty stomach 30 minutes before meals. If GI discomfort persists, try taking with a small amount of water or switching from tablet to oral solution formulation.
Skin rash
Uncommon allergic skin reactions including mild rash or urticaria have been reported in a small percentage of patients, particularly in pediatric populations.
Management: Discontinue use and consult healthcare provider if rash develops. Antihistamines may provide symptomatic relief. Rash typically resolves within days of discontinuation.
Headache
Mild headache has been reported infrequently during the initial days of treatment, possibly related to immune activation processes.
Management: Usually self-resolving within 2-3 days. Standard over-the-counter analgesics may be used if needed.
Nausea
Transient nausea may occur particularly at higher doses or when taken on a full stomach. More common during the first few days of treatment.
Management: Ensure dosing on an empty stomach. Taking with a small amount of water may help. If persistent, dose timing can be adjusted.
Diarrhea
Loose stools or mild diarrhea have been reported rarely, usually during the first week of treatment.
Management: Typically self-resolving. Maintain adequate hydration. If persistent beyond one week, consult healthcare provider.
Transient fever
A mild, transient increase in body temperature may occur as part of the immune activation response, particularly during the first few days of use.
Management: Usually resolves within 24-48 hours without intervention. Monitor temperature and use antipyretics if needed.
Less Common
- •Allergic reaction
These typically resolve with continued use or dose adjustment.
Stop and Seek Help If
- ×Severe or worsening side effects that don't improve with dose adjustment or supportive care
- ×Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
- ×Your healthcare provider recommends discontinuation based on your clinical response
- ×Development of any new medical condition that may be contraindicated with Pidotimod
- ×Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
- ×Abnormal lab results or clinical markers that suggest adverse effects
Pidotimod should only be started, adjusted, or discontinued under medical supervision. This information is for educational purposes only and does not replace professional medical advice. Never stop a prescribed treatment without consulting your healthcare provider first, as abrupt discontinuation may have consequences.
Interactions
With other peptides
- ✓Both enhance immune function through different mechanisms. Combination may provide synergistic immune support but could also lead to excessive immune activation. Use together only under medical supervision.
- ✓Similar T-cell modulating effects. Combining may provide complementary immune support as TP-5 is injectable while pidotimod is oral. Monitor for signs of excessive immune stimulation.
- ✓No known negative interaction. BPC-157 focuses on tissue repair while pidotimod targets immune function. These can likely be used concurrently without issues.
With medications
- !Immunosuppressants (cyclosporine, tacrolimus) - Pidotimod's immune-stimulating effects may counteract the immunosuppressive action of these drugs. Avoid concurrent use or use only under close medical supervision.
- ✓Antibiotics - Pidotimod is commonly used as an adjunctive therapy alongside antibiotics during acute infections. Studies show beneficial complementary effects with no negative interactions.
- ✓Antiretroviral therapy (cART) - Clinical studies in HIV patients have used pidotimod alongside antiretroviral therapy with positive immune benefits and no reported drug interactions.
- ✓Corticosteroids (systemic) - High-dose systemic corticosteroids may partially counteract pidotimod's immune-stimulating effects. Low-dose or inhaled corticosteroids are generally compatible.
With supplements
- ✓Vitamin D - Complementary immune support. Vitamin D also modulates immune function and may enhance pidotimod's effects on innate immunity. Safe to combine.
- ✓Zinc - Zinc supports immune cell function and may complement pidotimod's immunomodulatory effects. Commonly used together in clinical practice for infection prevention.
- ✓Probiotics - Probiotics support gut-associated immune function and may complement pidotimod's systemic immune effects. No known negative interactions.
- ✓Echinacea - Both have immunostimulant properties. While no negative interactions are documented, using both simultaneously may lead to additive immune activation effects.
