- in users with a shaved scalp
- if occlusive dressings or other topical medical preparations are being used.
4.4. Special warnings and precautions for use
Before using Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam, the user should determine that the scalp is normal and healthy. Topical minoxidil should not be applied to inflamed, infected, irritated or painful scalp skin (see section 4.3).
Topical minoxidil is not indicated when there is no family history of hair loss, hair loss is sudden and/or patchy, hair loss is due to childbirth, or the reason for hair loss is unknown.
The patient should stop using Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam and see a doctor if hypotension is detected or if the patient is experiencing chest pain, rapid heartbeat, faintness or dizziness, sudden unexplained weight gain, swollen hands or feet or persistent redness or irritation of the scalp or other unexpected new symptoms occur (see section 4.8).
Patients with known cardiovascular disease or cardiac arrhythmia should contact a physician before using Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam.
Some patients have experienced changes in hair colour and/or texture with this product use.
Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam is for external use only. Do not apply to areas of the body other than the scalp.
Using more than the recommended dose or more often will not improve results.
Unwanted hair growth may be caused by the transfer of the product to areas other than the scalp.
Hands should be washed thoroughly after applying the foam.
Some consumers reported increased hair shedding upon initiation of therapy with Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam. This is most likely due to minoxidil's action of shifting hairs from the resting telogen phase to the growing anagen phase (old hairs fall out as new hairs grow in their place). This temporary increase in hair shedding generally occurs two to six weeks after beginning treatment and subsides within a couple of weeks. If shedding persists (> 2 weeks), users should stop using Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam and consult their doctor.
Users should be aware that, whilst extensive use of Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam has not revealed evidence that sufficient minoxidil is absorbed to have systemic effects, greater absorption because of misuse, individual variability, unusual sensitivity or decreased integrity of the epidermal barrier caused by inflammation or disease processes in the skin (eg. excoriations of the scalp, or scalp psoriasis) could lead, at least theoretically, to systemic effects.
Accidental ingestion may cause serious cardiac adverse events. Therefore this product has to be kept out of the reach of children.
Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam contains 536.3 mg of alcohol (ethanol) in each 1 g. It may cause burning sensation on damaged skin. Ethanol may cause burning and irritation of the eye. In the event of accidental contact with sensitive surfaces (eye, abraded skin and mucous membranes) the area should be bathed with large amounts of cool tap water.
Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam also contains butylated hydroxytoluene, which may cause local skin reactions (e.g. contact dermatitis), or irritation to the eyes or mucous membranes, and cetyl and stearyl alcohol, which may cause local skin reactions (e.g. contact dermatitis).
Hypertrichosis in children following inadvertent topical exposure to minoxidil:
Cases of hypertrichosis have been reported in infants following skin contact with minoxidil application sites of patients (caregivers) using topical minoxidil. Hypertrichosis was reversible, within months, when infants were no longer exposed to minoxidil. Contact between children and minoxidil application sites should therefore be avoided.
4.5. Interaction with other medicinal products and other forms of interaction
This product should not be used concomitantly with other medications applied topically on the scalp (see section 4.3).
Topical drugs, such as corticosteroids, tretinoin, dithranol or petrolatum, which alter the stratum corneum barrier, could result in increased absorption of minoxidil if applied concurrently. Although it has not been demonstrated clinically, there exists the theoretical possibility of absorbed minoxidil potentiating orthostatic hypotension caused by peripheral vasodilators.
Guanethidine has been reported to interact with oral formulations of minoxidil resulting in rapid and pronounced lowering of blood pressure.
There is a theoretical possibility that topical minoxidil may also interact with guanethidine.
4.6. Fertility, pregnancy and lactation
This product should not be used during pregnancy or lactation.
Pregnancy
There are no adequate and well-controlled studies in pregnant women. Studies in animals have shown a risk to the foetus at exposure levels that are very high compared to those intended for human exposure. There is potentially a risk of foetal harm in humans (see section 5.3).
Lactation
Systemically absorbed minoxidil is secreted in human milk. The effect of minoxidil on newborns/infants is unknown.
4.7. Effects on ability to drive and use machines
This product may cause dizziness or hypotension (see section 4.8). If affected, patients should not drive or operate machinery.
4.8. Undesirable effects
The safety of topical minoxidil from clinical trial data is based on data from 7 placebo-controlled randomised clinical trials in adults evaluating either 2% or 5% minoxidil solution, and two placebo-controlled randomised clinical trials in adults evaluating a 5% foam formulation. Adverse drug reactions (ADRs) identified during clinical trials and post-marketing experience with minoxidil are included in the table below by System Organ Class (SOC).
The frequencies are provided according to the following convention:
Very common (≥1/10); common (≥1/100, <1/10); uncommon (≥1/1,000, <1/100); rare (≥1/10,000, <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data).
ADRs are presented by frequency category based on 1) incidence in adequately designed clinical trials or epidemiology studies, if available, or 2) when incidence cannot be estimated, frequency category is listed as 'Not known'

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
4.9. Overdose
Increased systemic absorption of minoxidil may potentially occur if higher-than-recommended doses of Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam are applied to larger surface areas of the body or areas other than the scalp.
Because of the concentration of minoxidil in Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam, accidental ingestion has the potential of producing systemic effects related to the pharmacological action of the drug (2 g of Regaine for Men Extra Strength Scalp Foam 5% w/w Cutaneous Foam contains 100 mg minoxidil; the maximum recommended adult dose for oral minoxidil administration in the treatment of hypertension). Signs and symptoms of minoxidil overdosage would primarily be cardiovascular effects associated with sodium and water retention. Tachycardia, hypotension, dizziness and lethargy can also occur.
Treatment
Treatment of minoxidil overdosage should be symptomatic and supportive.
Fluid retention can be managed with appropriate diuretic therapy. Clinically significant tachycardia can be controlled by administration of a beta-adrenergic blocking agent.
