Although severe reactions are uncommon, possible serious side effects include itching, hives, and pain. These side effects are usually a result of an allergic reaction. Although scary, such reactions to Tretinoin are very rare. If you are allergic to drugs that contain Vitamin A (such as Isotretinoin), you may be at higher risk for an allergic reaction.

What is tretinoin and what is it used for Tretinoin cream is indicated for the topical treatment of acne vulgaris. The exact mechanism of action of tretinoin gel is unknown although it may have something to do with the fact that tretinoin activates three types of retinoic acid nuclear receptors. Additional evidence indicates that topical tretinoin cream may decrease microcomedone formation with reduced cohesiveness of follicular epithelial cells with the added effect of comedone extrusion. Tretinoin is similar structurally to adapalene.
Tretinoin gel is white to pale yellow in color and opaque in appearance. Tretinoin cream is typically prescribed in the form of all-trans-retinoic acid and is a metabolite of naturally occurring vitamin A. Tretinoin microspheres are available as tretinoin 0.04%, 0.08% and 0.1% gels. Often, the recommended protocol is to administer a thin layer of tretinoin cream once a day at night to places on the skin where lesions occur. Tretinoin prescription medication should generally be kept at 20 to 25 C and the pump should be stored upright. Depending on one's insurance, some or all of the out-of-pocket costs of tretinoin cream may be covered. Tretinoin coupons may also be available online if someone is looking to reduce the costs of the medication. Tretinoin ointment is combined with the drugs fluocinolone and hydroquinone to form Tri-Luma cream (used in melasma treatment).
Generic and branded tretinoin cream are prescription medications. Because of this, one cannot simply buy tretinoin online in the United States and or get tretinoin OTC (over-the-counter) as the first step is consulting a medical provider. However, Push Health can connect people interested in getting a tretinoin prescription, including tretinoin micro, tretinoin cream and tretinoin gel, with an online medical provider who can prescribe tretinoin ointment when appropriate.
Tretinoin cream use can cause side effects. The most common side effects resulting from tretinoin use include skin pain, itching, skin irritation, pharyngitis and erythema. Tretinoin gel should not be used in the setting of unprotected exposure to sunlight including sunlamps or in extreme weather. People with a tretinoin cream known hypersensitivity or allergy should not use the medication. Tretinoin and alcohol should not be used together. Before using tretinoin medication, patients should discuss all concerns and possible side effects with one's medical provider and pharmacist.

Retin-A Cream is a prescription skin cream used to treat acne. Retin-A Cream contains the active ingredient tretinoin and belongs to the retinoid drug class. Retinoids are chemically similar to vitamin A and help support skin health.
Precautions: Exposure to sunlight, including sunlamps, should be minimized during the use of Tretinoin Cream and Gel, and patients with sunburn should be advised not to use the product until fully recovered. Patients who have considerable sun exposure due to occupation and those with inherent sensitivity to the sun should exercise particular caution. Use of sunscreen products and protective clothing over treated areas is recommended when exposure cannot be avoided. Weather extremes, such as wind or cold, also may be irritating to patients using tretinoin. Tretinoin Cream and Gel should be kept away from the eyes, the mouth, angles of the nose, and mucous membranes. Topical use may induce severe local erythema and peeling at the site of application. If the degree of local irritation warrants, patients should be directed to use the medication less frequently, discontinue use temporarily, or discontinue use altogether.
Retinoids, a class of synthetic and naturally occurring Vitamin A compounds and derivatives, are popular and potent treatments for improving skin complexion and texture. Obagi offers a comprehensive portfolio of both cosmetic and prescription retinoid products for a wide range of needs including cosmetic retinol or retinaldehyde, or prescription retinoic acid, or tretinoin.
Thereafter, Bhawan and colleagues (1995) evaluated the changes occurring at the dermal level in Caucasian skin after daily application of 0.05% tretinoin cream for a period of 12 months. Interestingly, no significant changes were observed at 6 months in the papillary dermis in the tretinoin-treated group, which supported the observation made in the initial short-term studies. However, after 12 months, formation of new collagen fibers as well as reduction in nodularly degenerated microfibrillar material was observed in the tretinoin-treated group. This study indicated that for appreciable dermal level improvement, more than 6 months of tretinoin therapy is required. This also provided an explanation why remarkable changes were observed only after 6 months of tretinoin treatment in the study carried out by Green and colleagues (1993). Olsen and colleagues (1997a) evaluated the histological and clinical changes occurring in 298 patients after once daily application of either 0.05% or 0.01% tretinoin emollient cream for a duration of 1 year. Significant improvement in histological and clinical markers was observed in both the 0.05% and the 0.01% tretinoin group as compared with vehicle. In another study, Oslen and colleagues (1997b) evaluated the 6 month effect of once weekly or thrice weekly 0.05% tretinoin emollient or no treatment in 126 individuals who had completed 48 months of 0.05% once daily tretinoin therapy. Thrice weekly tretinoin treatment appeared to be more effective in improving the fine wrinkles than once weekly therapy whereas discontinuation of the therapy resulted in the reversal of beneficial effects to some extent.
Hence, in order to minimize or avoid these disadvantages, Kligman and colleagues (1998) evaluated the potential of high strength tretinoin (0.25% solution in a fast penetrating vehicle) for the treatment of photoaging in 50 females. The treatment regimen consisted of application of highly concentrated tretinoin solution on alternate nights for 2 weeks and then every night thereafter until the end of the treatment. Interestingly, just 4 to 6 week treatment with high strength tretinoin resulted in improvement in fine wrinkling, mottled hyperpigmentation, elasticity, hydration, angiogenesis, and new collagen deposition above the zone of solar elastosis and the extent was similar to the results observed after 6 to 12 months of standard tretinoin therapy (0.05%). Moreover, the high strength tretinoin treatment was well tolerated in all patients. Subsequently, Cuce and colleagues (2001) evaluated efficacy of the 1% tretinoin solution applied twice a week in 15 women with photodamaged skin. Histological studies carried out after 15 days showed compaction of stratum corneum and increased epidermal thickness. Additionally, surface imaging studies showed improvement in skin texture and appearance.
Similarly, Maddin et al (2000) conducted a multicentric, double-blind and placebo-controlled trial of 0.1% isotretinoin cream in 800 patients with moderate-to-severe photodamage. After 36 weeks of continuous daily treatment, the isotretinoin-treated group showed statistically significant (p < 0.01) amelioration exceeding the one in the vehicle treated group in overall appearance, fine wrinkles, texture, coarse wrinkling, and hyperpigmented macules after 12 weeks of treatment which was evident up to 36 weeks. Moreover, histological studies indicated a significant increase in epidermal thickness of skins obtained from the isotretinoin-treated group. However, no significant changes were observed in other histological parameters, such as dermal elastosis, thickness of the dermis, epidermal melanin content, number of fibroblasts, and melanocyte dysplasia or keratinocyte atypia. Although five to ten percent patients experienced severe irritation, particularly on facial skin, most of the other patients experienced only mild irritation. Moreover, the plasma level of isotretinoin did not show sustained increase in its concentration over the period of 36 weeks indicating absence of drug accumulation.
Topical isotretinoin has also been evaluated for the treatment of actinic keratoses. Alirezai and colleagues (1994) conducted a vehicle-controlled study which involved the use of 0.1% isotretinoin cream twice daily for 24 weeks. The study resulted in a statistically significant reduction in actinic keratoses and precancerous facial lesions in the isotretinoin group, with 66% of 44 patients achieving a reduction in more than one-third of lesions. However, no significant drug effect was seen for actinic keratoses on the scalp or upper extremities. Mild-to-moderate irritant reactions were observed in the isotretinoin treated group, but symptoms subsided with reduced frequency of the treatment. 59ce067264
