Addiction
SUD in females
People may face unique issues when it comes to substance use, as a result of both sex and gender.
-
Sex differences result from biological factors, such as sex chromosomes and hormones
-
While gender differences are based on culturally defined roles for men and women, as well as those who do not identify with either category. Gender roles influence how people perceive themselves and how they interact with others.
-
Sex and gender can also interact with each other to create even more complex differences among people
-
Women and men sometimes use drugs for different reasons and respond to them differently.
For example, women describe unique reasons for using drugs, including controlling weight, fighting exhaustion, coping with pain, and attempts to self-treat mental health problems. -
Women often use substances differently than men, such as using smaller amounts of certain drugs for less time before they become addicted.
-
Women can respond to substances differently. For example, they may have more drug cravings and may be more likely to relapse after treatment.
-
Sex hormones can make women more sensitive than men to the effects of some drugs.
-
Women who use drugs may also experience more physical effects on their heart and blood vessels.
-
Brain changes in women who use drugs can be different from those in men.
-
Women may be more likely to go to the emergency room or die from overdose or other effects of certain substances.
-
Women who are victims of domestic violence are at increased risk of substance use.
-
Divorce, loss of child custody, or the death of a partner or child can trigger women's substance use or other mental health disorders
-
Women who use certain substances may be more likely to have panic attacks, anxiety, or depression.
-
Some of the unique issues women who use drugs face relate to their reproductive cycles. Some substances can increase the likelihood of infertility and early onset of menopause.
-
Substance use during pregnancy can be risky to the woman’s health and that of her children in both the short and long term. Most drugs, including opioids and stimulants, could potentially harm an unborn baby.
-
Use of some substances can increase the risk of miscarriage and can cause migraines, seizures, or high blood pressure in the mother, which may affect her fetus. In addition, the risk of stillbirth is 2 to 3 times greater in women who smoke tobacco or marijuana, take prescription pain relievers, or use illegal drugs during pregnancy.
-
It is important to note that treatment for substance use disorders in women may progress differently than for men.
-
Women report using some substances for a shorter period of time when they enter treatment. However, women's substance use tends to progress more quickly from first use to addiction. Withdrawal may also be more intense for women. In some cases, women respond differently than men to certain treatments. For instance, nicotine replacement (patch or gum) does not work as well for women as for men.
SUD in pregnancy
The number of women misusing drugs has increased considerably and a significant number of women in the UK presenting to drug misuse services for treatment are of child-bearing age.
Every woman suspected of a positive pregnancy test requires appropriate history-taking, assessment and screening for alcohol and other drug use.
Drug and alcohol use during pregnancy is associated with both maternal and fetal/neonatal outcomes. Maternal outcomes include not receiving adequate prenatal care and fetal outcomes relate to a failure to thrive. Women of child-bearing age who smoke, consume more than two standard drinks a day, or use other drugs, should be informed of the potential risks to both themselves and the fetus, and offered advice and if necessary, told where to get help.
Where harmful, hazardous or dependent use is suspected or confirmed by the obstetrician, a specialist Drug and Alcohol service should be involved.
In collaboration with the Antenatal team, the Drug and Alcohol team can provide specific guidance on treatment and will monitor the patient’s alcohol and other drug use during pregnancy, following the birth of the baby, monitoring is continued by the neonatal team and the Drug and Alcohol teams. If the infant, or an older child, is considered to be at risk, involvement with child protection agencies or departments is mandatory.
The development of the fetus will be affected by factors such as quantity and frequency of use, and gestational stage and drug or alcohol use may lead to:
- Prematurity
- Low birth weight
- Withdrawal syndromes
- Perinatal mortality
- Teratogenic effects
- Sudden infant death syndrome: increased 4–5 fold in infants born to pregnant drug users
- Respiratory distress
- Convulsions
General complications of SUD during pregnancy
Effects on the mother:
Pharmacological effects of the drug:
Chaotic use may lead to:
- Overdose/intoxication
- Withdrawal syndromes (alcohol, benzodiazepines, stimulants, cannabis).
If injecting drugs, complications of injecting
- Bacterial infections:
As Septicemia
- Subacute bacterial endocarditis, septic thrombophlebitis
As Viral infections: Hepatitis B, C, HIV
- Fungal infections: As Candidiasis.
Emotional/Psychiatric complications
- Anxiety
- Depression
- Insomnia.
Psychosocial issues
- Involvement with Child Protection Agencies
- Domestic violence
- Financial problems
- Prostitution
- Criminal activity.
Obstetric complications
- Placental insufficiency, abruptio placentae, placenta previa
- Intrauterine growth retardation/death
- Premature rupture of membranes/premature labor
- Pre-eclampsia/eclampsia
- Chorioamnionitis
- Premature delivery
- Postpartum hemorrhage
Other medical complications
- Poor nutrition
- Vitamin deficiencies
- Anemia
Women who use substance during pregnancy should receive education and advice about safe sex and harm reduction strategies, and be screened for blood-borne viruses and sexually transmitted infections that are spread by vertical transmission.
It is advisable that tests are conducted for blood-borne viruses (hepatitis C, B, and HIV) early in pregnancy. All testing should be conducted in conjunction with pre and post-test counseling. Patient confidentiality must be maintained at all times.
- Hepatitis C: Up to 10% of mothers with chronic hepatitis C infection who are HCV RNA (PCR) positive can transmit hepatitis C virus to the fetus. The infant should be tested for HCV RNA PCR at 4–6 months and after 18 months when trans placental antibodies have disappeared. If HCV RNA PCR is positive after 6–18 months—refer to Pediatric Hepatologist or Infectious Disease Specialist.
- Hepatitis B: Women who are HBs Ab negative should be offered hepatitis B vaccination after birth, babies of HBs Ag positive mothers are given immunoglobulin within 12 h and a total of four doses of hepatitis B vaccination-at birth, 2, 4, and 6 months.
- HIV: The risk of vertical transmission of HIV is greatest during the last week of pregnancy and during birth. The risk can be reduced by elective caesarean section and intravenous antiretroviral therapy before birth. Zidovudine therapy reduces the risk of vertical transmission from 25% to 8%.
Effects of specific drugs in the pregnant women:
Nicotine
The vasoconstrictor effects of nicotine impair placental blood supply, while carbon monoxide reduces availability of oxygen to the fetus. The risk of harmful effects is greater in older mothers who smoke. Smoking cessation in early pregnancy will give the greatest benefit, although quitting smoking at any time during pregnancy is beneficial for both the mother and fetus.
Maternal risks: Higher risks of complications during pregnancy.
Fetal/infant risks:
-Low birth weight (the risk increases in mothers who continue to smoke during pregnancy)
-Congenital malformation (cleft palate, microcephalus and club foot)
- Increased risk of perinatal mortality
- Sudden infant death syndrome
Heroin
Pregnant intravenous drug users often have poor antenatal attendance, chaotic lifestyles and poor nutrition, and detoxification of pregnant heroin dependent women is risky. Maternal abstinence may result in fetal distress that may be more harmful than passive dependence, and induce abortion or premature labor. The highest risk period is before the 14th week and after the 32nd week of gestation.
Methadone maintenance treatment in conjunction with a comprehensive drug and alcohol and prenatal program is the treatment of choice to maintain the patient in a comfortable state
Babies born to opioid dependent mothers should be monitored for the neonatal abstinence syndrome, this is not life threatening and can be managed easily in Special Care Baby Units.
neonatal abstinence syndrome
Neonatal heroin abstinence syndrome
- Onset: following last illicit use: 24–36 h after delivery.
- Duration: >1–2 weeks.
Signs and symptoms :
- CNS: high pitched cry, tremor, sleep disturbance, increased muscle tone, myoclonic jerks, convulsions
- Respiratory: sneezing, yawning, nasal flaring and stuffiness, tachypnea, respiratory distress.
- Gastrointestinal tract: poor feeding, excessive sucking, regurgitation, projectile vomiting, diarrhea.
Neonatal benzodiazepine withdrawal syndrome
The use of benzodiazepines, particularly during the first trimester of pregnancy, is thought to be associated with decreased fetal growth, CNS abnormalities and dysmorphic features resembling FAS
Examination of pooled data from cohort studies found no association between fetal exposure to benzodiazepines during the first trimester and risk of major malformations or malformations of the oral cleft alone (cleft lip and cleft palate).
However, analysis of pooled data from case control studies showed a small but significant increased risk for major malformations or oral cleft palate alone. Fetal ultrasonography should be used to screen for cleft lip/palate when problematic benzodiazepine use is suspected or when dependent use is observed.
- ‘Floppy infant syndrome’: hypotonia, sucking difficulties, hypothermia or impaired temperature control
- Tremor
- Irritability
- Hyperactivity
- Cyanosis
Neonatal methadone withdrawal syndrome
- Onset: 5–15 days after delivery (i.e., following last dose).
- Duration: >1–2 weeks
Signs and symptoms:
- CNS: high pitched cry, tremor, sleep disturbance, increased muscle tone, myoclonic jerks, convulsions
- Respiratory: sneezing, yawning, nasal flaring and stuffiness, tachypnea, respiratory distress
- Gastrointestinal tract: poor feeding, excessive sucking, regurgitation, projectile vomiting, diarrhea.
Treatment
- Place on neonatal abstinence syndrome scale
- Nurse in a quiet environment and minimize stimuli
- Administer morphine with caution and only after seeking advice from the specialist neonatologist.
- Discharge planning is important
- Consider the safety of the child. In many regions there is an obligation to notify the Child Protection Services
Cocaine/crack cocaine
Cocaine causes vasoconstriction, thus reducing the blood flow to the placenta and increasing the risk of placental abruption. It also increases uterine contractility, thus increasing the risk of spontaneous abortion and premature delivery. The use of cocaine during pregnancy is associated with an increased risk of sudden infant death syndrome in the baby.
Fetal Alcohol Syndrome (FAS)
There are no internationally agreed guidelines regarding safe limits of alcohol consumption during pregnancy. The UK Department of Health recommends not more than 1–2 units of alcohol once or twice a week. Many countries follow similar guidelines as the US which advises total abstinence during pregnancy or in women who are considering pregnancy.
It is the result of harmful exposure to alcohol early in pregnancy and FAS is reported to be the leading preventable cause of mental retardation in western civilization
Drinking during pregnancy results in a 30–50% increased risk of delivering a fetus with FAE, particularly in older women >30 years of age. The detrimental effects of alcohol are greatest during the first trimester of pregnancy, often before the woman knows that she is pregnant. Thus, all women of child-bearing age should also be advised of the risks of drinking and restrict their drinking to a minimum if they are likely to become pregnant
The common pathway of alcohol teratogenesis appears to be its deleterious effects on the developing brain and nervous system. The times of greatest sensitivity of the fetal brain to maternal alcohol consumption are the first and third trimesters.
Sudden cessation of alcohol consumption in pregnant alcohol dependent women is associated with a high risk of seizures. Alcohol detoxification should not be conducted in the community, and needs very careful supervision by obstetricians and alcohol treatment specialists.
The teratogenic effects of alcohol cause developmental delay and birth defects:
- Characteristic facial abnormalities with underdevelopment of the middle of the face—depressed bridge of nose, thin upper lip, absent philtrum, flattened maxilla; also ‘bulls' eyes and low set ears
- Growth retardation (prenatal or postnatal)
- Cardiac abnormalities
- Behavioral disturbances
- Learning disability
- Prematurity, low birth weight; small for gestational age
- Fetal or neonatal death.
Breast feeding
Breast milk is generally regarded as the best nutrition for the child. In general, mothers should not be discouraged from breast feeding but should be given full information of the risks associated with continued use of alcohol and other substances.
Tobacco
- Minimal amounts are excreted into the breast milk.
- Offer the mother nicotine patches to reduce the risks associated with passive smoking
Cannabis
- Some cannabis is excreted in the breast milk, but the effects on the infant are unknown
Opioids
Mothers who are stable on methadone maintenance treatment may breast feed, but those who are unstable should not be encouraged to do so
Psychostimulants
- Advise regular and unstable users against breast feeding
- Inform intermittent users of the risks associated with breast feeding.
Alcohol
passes through the breast milk so drinking during breast feeding is not recommended
