Indications of Desolon
Approved Use
Desolon is a combined oral contraceptive (COC) indicated for the prevention of pregnancy in women who choose this method of contraception.
Additional Guideline-Supported / Off-Label Uses
- Menstrual cycle regulation — commonly used off-label to regulate irregular menstrual cycles.
- Management of dysmenorrhea (painful periods) — an off-label, adjunct use in women who also desire contraception.
- Adjunct management of mild-to-moderate acne or hirsutism in some women — an off-label use; combination hormonal therapy alone is not a first-line acne treatment.
These off-label uses should only be undertaken on a physician's advice, since Desolon is primarily approved and studied as a contraceptive.
Composition
Each tablet of Ethinylestradiol + Desogestrel typically contains a low dose of the synthetic estrogen ethinylestradiol (commonly 20–30 micrograms) combined with the third-generation progestin desogestrel (commonly 150 micrograms). Exact strengths and pack sizes (e.g. 21-tablet or 28-tablet packs with placebo tablets) vary by brand and market.
Description
Desolon is a fixed-dose combined hormonal oral contraceptive containing a synthetic estrogen (ethinylestradiol) and a synthetic progestin (desogestrel). It belongs to the class of combined oral contraceptive pills (COCs) that work primarily by preventing ovulation.
Desolon is taken once daily, generally in a cyclical or extended regimen depending on the specific product, and is one of the most widely prescribed methods of reversible hormonal contraception.
Therapeutic Class
Desolon belongs to the therapeutic class of Combined Oral Contraceptives (Estrogen + Progestin), also referred to as combined hormonal contraceptives.
Pharmacology
Mechanism of Action
Ethinylestradiol + Desogestrel prevents pregnancy through several complementary hormonal mechanisms:
- Inhibition of ovulation — the combination suppresses the hypothalamic-pituitary axis, reducing gonadotropin (FSH and LH) secretion and preventing the LH surge needed for ovulation.
- Cervical mucus changes — desogestrel thickens cervical mucus, impeding sperm penetration.
- Endometrial changes — the endometrium becomes less receptive to implantation.
Pharmacokinetics
Ethinylestradiol and desogestrel (converted to its active metabolite etonogestrel) are well absorbed orally, undergo hepatic metabolism, and are excreted mainly in urine and feces. Desogestrel is a third-generation progestin with high progestational selectivity and minimal androgenic activity.
Dosage & Administration of Desolon
Standard Contraceptive Regimen
| Regimen | Dosing Instructions |
|---|---|
| 21-day pack | One tablet daily for 21 days, followed by a 7-day hormone-free interval, then start the next pack. |
| 28-day pack | One active tablet daily for 21 days followed by 7 placebo/inert tablets, taken continuously with no break between packs. |
How to Start
- Day 1 start: Begin on the first day of the menstrual cycle — no backup contraception needed.
- Sunday start or other start: If started later than day 5 of the cycle, use a backup non-hormonal method (e.g., condoms) for the first 7 days.
Missed Pill Guidance
If one active pill is missed, it should be taken as soon as remembered, even if it means taking two pills in one day, and the pack should be continued. If two or more consecutive active pills are missed, backup contraception should be used and a physician or pharmacist consulted, as pregnancy risk increases. Desolon should always be taken at approximately the same time each day to maintain effectiveness.
Administration of Desolon
Desolon tablets are taken orally, with or without food, ideally at the same time each day to maintain steady hormone levels and maximize contraceptive reliability. Tablets should be taken in the order indicated on the blister pack. See "Dosage and Administration" for full start-up and missed-pill instructions.
Interaction of Desolon
Clinically Significant Drug Interactions
| Interacting Drug/Class | Mechanism | Clinical Consequence |
|---|---|---|
| Strong hepatic enzyme inducers (e.g., rifampin, rifabutin, certain anticonvulsants such as phenytoin, carbamazepine, topiramate, barbiturates, and St. John's Wort) | Induction of hepatic CYP3A4 enzymes increases metabolism of estrogen and progestin | Reduced contraceptive efficacy, breakthrough bleeding, and risk of unintended pregnancy; a backup non-hormonal method is recommended during and after use of the interacting drug |
| Lamotrigine | Desolon increases lamotrigine clearance | Reduced lamotrigine plasma levels, potentially reducing seizure control |
| HIV protease inhibitors / certain antiretrovirals | Alter hepatic metabolism of ethinylestradiol | May reduce or increase contraceptive hormone levels; alternative or additional contraception may be advised |
| Certain antibiotics (e.g., broad-spectrum antibiotics affecting gut flora) | Theoretical reduction in enterohepatic recirculation of ethinylestradiol | Uncommon but sometimes advised backup contraception during antibiotic courses |
Always inform your physician about all medicines, herbal products, and supplements being used before starting Desolon.
Contraindications
Ethinylestradiol + Desogestrel is contraindicated in women with any of the following conditions (true absolute contraindications):
- Known hypersensitivity to Ethinylestradiol + Desogestrel or any of its components
- Current or past history of deep vein thrombosis (DVT) or pulmonary embolism (PE)
- Current or past history of cerebrovascular disease (stroke) or coronary artery disease
- Valvular heart disease with thrombogenic complications

- Heavy smoking (15 or more cigarettes per day) in women over 35 years of age
Boxed Warning: Cigarette smoking increases the risk of serious cardiovascular events from combined oral contraceptive use, especially in women over 35 years of age. Women who use Ethinylestradiol + Desogestrel should be strongly advised not to smoke.
Side Effects of Desolon
Common Side Effects of Desolon
- Nausea, especially in early cycles
- Breast tenderness or enlargement
- Headache
- Breakthrough bleeding or spotting
- Mood changes
- Weight changes
- Decreased libido
Serious Side Effects
Serious but uncommon risks of Desolon include venous thromboembolism, stroke, myocardial infarction, hepatic adenoma, and hypertension — see "Precautions and Warnings" and "Contraindications" for full details. Seek urgent medical attention for leg swelling/pain, chest pain, sudden shortness of breath, severe headache, vision changes, or slurred speech.
Pregnancy & Lactation
Pregnancy
Desolon is contraindicated in pregnancy and is not intended for use once pregnancy is confirmed or suspected; it offers no benefit during pregnancy and hormonal exposure should be avoided. If pregnancy occurs while using Desolon, discontinue immediately and consult a physician promptly.
Lactation
Combined hormonal contraceptives containing ethinylestradiol may reduce milk quantity and quality and are generally not recommended until breastfeeding is well established, and are best avoided in the first several weeks postpartum. A progestin-only method is often preferred during lactation. Use Desolon during breastfeeding only if clearly needed and a physician determines the benefit outweighs the potential risk to milk supply and the infant.
Precautions & Warnings
Boxed Warning — Smoking and Cardiovascular Risk
Cigarette smoking increases the risk of serious cardiovascular events (heart attack, stroke, blood clots) from combined oral contraceptive use, and this risk increases with age (particularly over 35 years) and the amount smoked. Women who use Desolon should be strongly advised not to smoke.
Venous Thromboembolism (VTE) Risk
All combined hormonal contraceptives increase the risk of venous thromboembolism (blood clots). Some epidemiological studies suggest that desogestrel-containing pills such as Desolon may carry a somewhat higher VTE risk compared with certain other progestins; this risk should be individually assessed against the risk of unintended pregnancy, especially in women with additional risk factors (obesity, prolonged immobility, family history of VTE, older age).
Other Precautions Requiring Case-by-Case Evaluation
- Migraine without aura, or new-onset/worsening migraine — requires careful re-evaluation of continued use
- Mild hypertension that is well-controlled on medication — requires regular blood pressure monitoring
- Rule out pregnancy before initiating therapy
- Periodic physical examinations and blood pressure checks are recommended during long-term use
- Use with caution in women with a family history of breast cancer, gallbladder disease, or depression
See "Contraindications" for conditions in which Desolon must not be used at all.
Overdose Effects of Desolon
Overdose with Desolon is generally not associated with serious or life-threatening toxicity. Reported effects in adults and children may include nausea, vomiting, and withdrawal-type vaginal bleeding in females. There is no specific antidote. If overdose is suspected, seek immediate medical attention or contact a poison control center; treatment is supportive and symptomatic, and should be directed by a physician or emergency medical service.
Storage Conditions
Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.
Use In Special Populations
Renal Impairment
No specific dose adjustment data are established; use with caution and physician oversight.
Hepatic Impairment
Desolon is contraindicated in women with active liver disease or hepatic tumors (see "Contraindications").
Smokers
Desolon should not be used by women over 35 years who smoke heavily; smoking of any amount is discouraged in all users due to increased cardiovascular risk (see boxed warning).
Obesity
Contraceptive efficacy may be somewhat reduced in women with a higher body weight/BMI; alternative or additional contraceptive measures may be discussed with a physician.
Elderly
Desolon is intended for use during the reproductive years and is not indicated in postmenopausal women.
Duration Of Treatment
Desolon may be used continuously for as long as contraception is desired, provided no contraindications develop. Periodic (at least annual) physician review is recommended to reassess risk factors, blood pressure, and continued suitability of combined hormonal contraception.
Drug Classes
Ethinylestradiol + Desogestrel belongs to the drug classes: Combined hormonal contraceptives; Estrogen-progestin combination oral contraceptive; Third-generation progestin (desogestrel) with a synthetic estrogen (ethinylestradiol).
Mode Of Action
Ethinylestradiol + Desogestrel acts mainly by inhibiting ovulation through suppression of pituitary gonadotropin (FSH/LH) release, with additional contraceptive effects from thickened cervical mucus (impeding sperm transport) and altered endometrial receptivity (impeding implantation). See "Pharmacology" for full mechanistic detail.
Pregnancy
X (FDA legacy pregnancy category — combined hormonal contraceptives are contraindicated in pregnancy)
Pediatric Uses
Desolon is indicated for contraception only after the onset of menses (menarche). Safety and efficacy have not been established in premenarchal females, and Desolon has no indication before menarche. In adolescents after menarche, the same dosing, contraindications, and precautions apply as in adult women, with appropriate counseling regarding compliance and side effects.
